Tailored Fiber Plaplacement cement (TFP) i

📢Time to Get Technical...📢

Tailored Fiber Plaplacement cement (TFP) is an embroidery-based tow-steering process that enables complete control over fiber and directionality in a composite preform. During the process, continuous tow is stitched to a backing material using numerical control. The result is highly engineered composite structures that take full advantage of the anisotropic nature of fiber reinforcement.

Several fibrous materials like carbon, glass, basalt, aramid, natural, thermoplastic, ceramic fibers, or metallic threads can be placed in a near-net shape on a carrier material by TFP. Even the placement of different materials at the same time or one after another can be proceeded by TFP. Especially while using the TFP technology for the placement of carbon rovings to create

preforms for composite parts, a high degree of freedom is an advantage. The rovings can be placed exactly according to the distribution of forces within a structural component. This leads to a higher force absorption with fewer stacked layers. 100% reproducibility speaks for itself and is accomplished by the following:

- Automatic perform production.

- Low mass tolerance.

- High dimensional accuracy.

- Reliable identical laying roving.

This cost-effective process is driven by high stitching speed on one hand and multiple laying heads on a machine. In comparison to other textile technologies, the expensive loss of materials is kept to a minimum because of the near-net-shape production of the product. Accordingly, the problem of waste disposal is very little.

Hexagon Purus receives an order to deliver high-performance hydrogen distribution systems to a leading global industrial gas company

 (Oslo, 20 April 2022) Hexagon Purus, through its wholly-owned subsidiary, Wystrach GmbH (“Wystrach”), a leading hydrogen systems supplier, has received a follow-on order worth approximately EUR 1.5 million (approx. NOK 14 million) to deliver hydrogen distribution systems to a leading global industrial gas company. This order can be viewed in conjunction with the announcement on February 4, 2022, of a separate order with a value of approximately EUR 5.7 million (approx. NOK 58 million). Wystrach’s hydrogen distribution systems with Hexagon Purus’ type 4 cylinders will be used to deliver hydrogen for industrial and mobility applications in the Netherlands.

CST composites targets green hydrogen supply chain

 After 26 years in business, Australia’s CST Composites is positioning itself to be a leading player in the global green hydrogen supply chain through a joint venture with US-based hydrogen storage tank manufacturer Optimum Composite Technologies.

The joint venture will see CST Composites expand its core capabilities to support the growth of Optimum’s business in designing and producing Composite Pressure Vessels (CPVs), which are used to store hydrogen and Renewable Natural Gas (RNG) and have many other applications.

CST has two manufacturing facilities in Australia and the growth plans include establishing Australia’s first hydrogen vessel manufacturing facility, which will service emerging and growing demand from the defence (e.g. VTOL vehicles), space (e.g. rockets), transport and energy sectors.

This manufacturing facility will help advance Australia’s National Hydrogen Strategy, which highlights the need to develop the country’s supply chain infrastructure, including hydrogen storage tanks. High-pressure storage tanks at low cost will be a crucially important part of transport, building backups and many other aspects of hydrogen adoption.

The joint venture will complement both companies’ manufacturing abilities. CST Composites will have access to Optimum’s technical expertise and Intellectual Property (IP) in carbon fibre pressure vessels. CST Composites will also gain greater access to US markets for its high quality, filament-wound composite tubing by leveraging Optimum’s US facilities, customer base and supply chain.

CST Composites managing director, Clive Watts, said “High-pressure gas storage vessels is one of the biggest and fastest-growing markets globally for advanced composites, particularly for filament-wound carbon fibre composites”.

Recent significant corporate developments include South Korean Hanwha Solutions’ acquisition of US hydrogen storage tank manufacturer Cimarron Composites and its plans to invest US$100 million to expand the business.

The Australian Government is investing $1.4 billion to position Australia as a major hydrogen player by 2030. Mr Watts said “we will be applying for the grants and financial support available to advance our projects, which focus on the innovative design and development of hydrogen and CPV products. We are planning to make a significant investment to grow our new joint venture”.

CST Composites is a leader in filament winding technology and 90 per cent of its products are exported to Europe, the US, China and Asia. All of its profiles and tubing are currently manufactured at its high-tech facilities in Sydney. The company was a recent recipient of funding under Round 2 of the Australian Government’s Manufacturing Modernisation Fund.

The main properties of Composite materials

 📢Time to Get Technical...📢

Let's learn more about the main properties of composite materials!

As you may know, the characteristics/properties of composite materials resulting from the combination of reinforcement and matrix depend on the proportions of reinforcements and matrix, the form of the reinforcement, and the fabrication process.

But what are the most remarkable properties of these materials?

- Composite materials generally possess very high specific mechanical properties.

- Composite materials do not yield: their elastic limits correspond to the rupture limit.

- Composite materials have high strength under fatigue loads.

- Composite materials age under the action of moisture and heat.

- Composite materials do not corrode, except in the case of contact aluminum with carbon fibers in which galvanic phenomenon creates rapid corrosion.

- Composite materials are not sensitive to the common chemicals used in engines: grease, oils, hydraulic liquids, paints and solvents, petroleum. However, cleaners for paint attack the epoxy resins.

- Composite materials have medium- to low-level impact resistance (inferior to that of metallic materials).

- Composite materials have excellent fire resistance as compared with the light alloys with identical thicknesses. However, the smoke emitted from the combustion of certain matrices can be toxic.

But how do they fair against each other when it comes to specific strength in different temperatures? Which composites can be used in high-temperature applications?

composites in Aerospace

 2022 Technologies in Aerospace Composite Process

Composites are used in the #aerospaceindustries; those are termed #aerospace composite. The composite materials are light in weight. The lightweight of composite structural aerospace parts helps reduce the overall weight of the aircraft, thereby leading to a better weight ratio. The structural parts manufactured using composites tend to be light in weight and possess high strength. Composites are used to make various parts of #aircraft like engine blades, interiors, and nacelles.

DYNAPIXEL

 📢Saturday Spotlight!📢 DYNAPIXEL tool!

Cikoni is trying to solve a recurrent problem in the composites industry: the high costs of the tools and molds that are necessary for every fiber composite manufacturing technology and for every new geometry to be built.

This is where the reconfigurable DYNAPIXEL tool system comes in. By means of a discretization of the tool surface with actuated pins, rapid prototypes or customer-specific components can be created without recurring tooling costs. An elementary constituent for the efficient use of the tool is a closed digital process chain. The DYNAPIXEL software uses script-based generation of support points directly in CAD and the seamless transfer of this data to the control

software of the DYNAPIXEL tool. This also enables the fast, adaptive production of components.

DYNAPIXEL also uses a silicone membrane, which can be used as a laminating surface and with molding processes up to 180°C. For double-diaphragm forming, you would enter the CAD data, let the software actuate the mold geometry, apply a vacuum to draw down the silicone surface on top, laminate the composite plies, close the matched mold with a second membrane and complete the cure.

Surface finish has not been a driving issue because DYNAPIXEL was developed as a tool to speed R&D. Cikoni's goal was to produce additional molds and design iterations without much additional cost. "Once you freeze the part design, you would then switch to CNC-machined metal molds. You can also use this as a performing tool", says Farbod Nezami, one of CIKONI’s co-founders.
