Today's KNOWLEDGE Share : Hengshen carbon fibre cables

Today's KNOWLEDGE Share 

Hengshen carbon fibre supports one of the world’s tallest bridges:

The first main cable strand of the Huajiang Canyon Bridge, one of the world’s highest bridges under construction located in China’s Guizhou province, was successfully installed, realizing stress monitoring by using grating optical fibre (composite carbon fibre filament) on the 2,378-metre-long main cable.

The intelligent carbon fibre cables used in the project were jointly designed by Hengshen, China’s major carbon fibre and composite materials producer, and Three Gorges University, and manufactured by Hengshen. The company underlines that “this fully proves Hengshen’s technical strength and product quality, and highlights the company’s competitiveness and influence in the field of intelligent monitoring of carbon fibre composite materials.”

The application of this stress and strain monitoring technology on a long-span suspension bridge is the first of its kind in the world, taking a key step towards innovation and empowerment of intelligent condition monitoring for suspension bridges, according to Hengshen.

The smart cable is a fibre optic array sensing device installed in the main cable strands of the bridge to perform condition monitoring of the main cable. It is equivalent to the “nervous system” of the bridge’s main cable. The safety of the main body of the bridge is monitored through the stress changes of the cable strands. A network fibre is also configured to monitor the temperature and humidity of the cable’s internal environment. The aim is to monitor and understand whether the internal environment of the cable affects the durability of the main cable and whether the outer protection of the main cable is damaged. In addition, the smart cable is also equipped with a dehumidification system to ensure that the internal humidity of the main cable is within a reasonable range, to effectively protect the main cable, preventing corrosion, and extending its service life. 

“With the continuous development of science and technology, Hengshen people will keep on making improvements and breakthroughs to help the rapid development of intelligent health monitoring of suspension bridges in China“, says Hengshen. The company has five thousand-ton carbon fibre production lines with an annual production capacity of 5,000 tons of carbon fibre. The product portfolio covers raw silk, carbon fibre, sizing agents, fabrics, liquid resins, adhesives, prepregs, carbon fibre composite parts, and aviation composite structural parts.

Dentsply Sirona Introduces Adhesive with Moisture Control

Dentsply Sirona has introduced Prime&Bond Active, a universal adhesive designed to enhance the reliability of dental restorations by managing moisture levels during application. The product's adhesive chemistry technology is designed to ensure consistent performance across diverse moisture conditions, supporting strong adhesive bonds without compromising simplicity or predictability.

Prime&Bond Active's blend of hydrophobic and hydrophilic properties help the product overcome the surface tension of water, which allows the adhesive to spread evenly across dentin and into dentinal tubules in a uniform, homogenous layer that leaves a strong, reliable bond after air-drying. This "active spreading" minimizes the risk of dry spots that can lead to postoperative sensitivity or micro leakage. 

To reduce the risk of patient sensitivities, the formula is created without 2-hydroxyethl methacrylate (HEMA), TGDMA or bisphenol.

Researchers to Develop Bio-based Plasticizer for Elastomers and Thermoplastics

 The Fraunhofer Institute for Microstructure of Materials and Systems IMWS is working with partners to develop a non-toxic plasticizer. This plasticizer will also be marketable, completely bio-based, and for use in elastomers and thermoplastics.

Using rapeseed oil as a starting product, more sustainable solutions for tires and packaging should become possible. The project partners also want to design a corresponding pilot plant in central Germany as part of the "Biocerine" project.

Finding Alternatives from Renewable Raw Materials

Plasticizers are used to make plastics more flexible and pliable during the manufacturing process and/or during subsequent use. However, common industrially produced plasticizers such as phthalates are viewed critically because some of them can be potentially harmful to health and/or pollute the environment.

“Such plasticizers are not only frequently used in traditional plastics, but also in biopolymers, whose environmental compatibility they then impair. For this reason, alternatives are being sought worldwide that offer at least comparable quality at affordable prices and can ideally be produced from renewable raw materials,” says Dr. Patrick Hirsch, Group Leader “Sustainable Materials and Processes”, who is leading the project at the Fraunhofer IMWS.

This is precisely the solution the partners want to find within the project, which is being funded by the Federal Ministry of Education and Research as part of the “WIR! - Change through Innovation in the Region” program.

The consortium is relying on the expertise and opportunities already available in Central Germany. In addition to the Fraunhofer IMWS, GLACONCHEMIE GmbH and Polymer Service GmbH from Merseburg are also involved, while Folienwerk Wolfen, Expinos GmbH and Reifenwerk Heidenau GmbH will test the product samples created in the research project as associated partners.

New Plasticizer to Have Improved Migration Behavior:

The project partners are focusing on bio-based glycerin derivatives, which are obtained on an industrial scale from rapeseed oil, for example, and can be specially adapted to the requirements of different polymer materials.

The new type of plasticizer should have improved migration behavior in thermoplastic and elastomeric biopolymers, which has advantages in particular for the processability and long-term use of these materials.

“Specifically, we want to produce alcohols from this bio-based glycerin, which are then esterified with special fatty acids. In the second step of the synthesis, their double bonds are epoxidized,” says Hirsch, describing the approach. The bio-based plasticizers developed are then incorporated into thermoplastic and elastomeric biopolymers, for example for films, packaging, or tire compounds.

Researchers Develop High-strength Composite by Upcycling Common Polymer Foams

A team of researchers led by UCLA chemical engineers has discovered a way to make tough and durable composite materials with strength comparable to that of cement by recycling a common polymer foam found in sofas and mattresses. 

Inspired by Unique Microstructure of Clamshells:

The discovery was inspired by naturally occurring high-strength materials, such as clamshells or nacre the shiny material of which pearls are made. These materials are characterized by their unique microscale structure of interconnected plates, which makes them very resistant to cracking under stress.

Led by Samanvaya Srivastava, an associate professor of chemical and biomolecular engineering at the UCLA Samueli School of Engineering, the research team aimed to create a synthetic composite material composed of both inorganic and organic phases with comparable strength, which has been a longstanding challenge in the field.

Published in ACS Polymers Au and featured on the journal’s February cover, the study highlights the new material’s rock-like nature. The composite has a lighter weight, requires shorter curing time and possesses stronger bend strength than cement — which, mixed with water or sand, makes concrete for building infrastructure. 

“The simplicity of the fabrication approach and the potential of this material for applications in diverse fields really set it apart from other composites.

The composite also creates a new recycling route for polyurethane foam, commonly used in furniture like sofas and mattresses or inside vehicles, due to its cushioning properties and durability. Until now, recycling these materials has been challenging, as the resulting products often have inconsistent properties, such as being chemically unstable and having undesirable colors.

Does Not Require Complicated Processing Conditions:

“These high-strength composites can perform as excellent thermal and acoustic barriers.To make them, we have designed a chemical pathway to upcycle a common polymer into materials with superior mechanical and functional properties as compared to commercially available materials, including cement.” 

Previous attempts to produce similar biologically inspired composite materials predominantly featured metal alloys and minerals, such as aluminum oxide. Unfortunately, these materials require the use of high temperatures and extensive processing. Recent attempts have utilized polymers in combination with inorganic materials, such as graphite and zinc oxide. Polymers are preferable due to their relatively widespread availability, strength and flexibility.

Could be a Sustainable Alternative to Cement:

The new composite material features permanent chemical covalent bonds between recycled organic compound polyols and naturally occurring inorganic materials, which contribute to its strength and durability.

igus Unveils First Recyclable Plastic Bicycle Frame for E-Bikes

igus continues to expand its bicycle component business and presents the first injection-molded polymer bicycle frame for Advanced Bikes.

 igus®, a leader in motion plastics, has developed the first recyclable plastic bicycle frame for the German e-bike manufacturer Advanced Bikes. Building on the success of RCYL, a bicycle made from 50% recycled fishing nets, this new innovation supports sustainable mobility. Leveraging decades of expertise in plastics manufacturing, igus has created a high-performance, injection-molded polymer frame and new bicycle components for Advanced Bikes.

Revolutionizing Bicycle Frame Production

In 2023, e-bike sales in Germany surpassed traditional bicycles for the first time, driven by environmental awareness. However, most bike frames today are made of steel, aluminum, or carbon fiber, materials that are energy-intensive to produce and often end up in landfills. To address this, Advanced Bikes partnered with igus to develop a sustainable composite plastic bicycle frame, now featured in the new Reco Urban trekking e-bike.

“Advanced’s goal was to create an injection-molded composite frame from 100% recyclable plastic,” says Jan Philipp Hollmann, Head of Bike Components at igus. “With over 30 years of experience in developing components like plain bearings, rod ends, gears, and spherical bearings, we embraced the challenge of designing and producing this innovative frame.”

Environmental Benefits and Advanced Design:

To ensure the frame’s strength, rigidity, and low weight, igus uses a composite material of high-performance plastics and carbon fibers in granulate form. The company quickly developed a multi-part injection molding tool to achieve the frame’s complex geometry, resulting in a 3.3 kg lightweight, corrosion-resistant, and durable single-piece frame. Manufacturing in Germany allows for short logistics distances and just-in-time production aligned with demand. Additionally, igus’s “chainge” recycling program can regranulate end-of-life frames for reuse.

“In the future, we plan to produce other recyclable bicycle components such as pannier racks, rims, handlebars, and seat posts using injection molding,” explains Helge von Fugler, founder and Managing Director of Advanced Bikes. “This is essential for creating a fully recyclable e-bike.”

High-Performance Plastic Components:

igus produces bicycle frames using both injection molding and rotomolding at its headquarters in Cologne. Beyond frames, igus’s expertise extends to new bicycle components, including wheels, cranks, handlebars, and planetary gears. These high-performance plastic components are lightweight, lubrication-free, and corrosion-resistant, making them easy to clean and maintain.
