The final crack is only the last chapter of a much longer story.


Before a polymer breaks, invisible events are already happening inside the material:


๐Ÿงฌ Polymer chains begin to move and rearrange

⚠️ Weak points become stress concentration zones

๐Ÿ” Microvoids and small defects start to develop

๐Ÿ“ˆ Damage slowly accumulates under mechanical loading

.

By the time we see a crack…

The material has already been changing for a long time.

This is why understanding polymer failure is not only about observing the fracture surface.

.

It is about understanding what happened before the fracture.

The real question is not: "Where did the polymer break?"

.

The deeper question is: "Why did the material allow the damage to grow?"

.

From product design to failure analysis, polymers always leave clues before they fail.

.

A fracture surface is not just a broken part.

It is a record of the material's history. ๐Ÿงฉ

Today's KNOWLEDGE Share : Robotic 3D printing can compete with traditional boatbuilding

Image
Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...

Today's KNOWLEDGE Share : A BUG IN INJECTION MOLDING

Image
Today's KNOWLEDGE Share A bug in injection molding – an injection-molded part in a bug? Neither! Nature and injection molding have reached similar results. Nature created the first micro-gear long before any human engineering existed. One such example is the Issus coleoptratus (shown in the picture). Furthermore, only now are we reaching the point where injection-molded polymer microgears can approach this level of performance. Looking at the images, which one do you think is the natural gear, and which one is the molded version? It is not that easy to tell, right? Their appearance and operating principles are surprisingly similar. Chitin, a natural linear polymer, forms what nature essentially "molds” into shape. In engineering, we rely on advanced technical polymers to produce similar geometry through actual injection molding. They are not the same material, yet they solve the same issue: Stiffness, dimensional stability, and reliable function at a scale where tolerances...

Lummus Technology announced Vioneo has selected its Novolen®

Image
polypropylene (PP) technology for a new grassroots plant in #Antwerp , Belgium. The plant will be part of Vioneo’s complex that, once complete, will be the world’s first industrial scale fossilfree plastics production complex. The complex, based on green methanol as feedstock, will also be highly electrified using renewableelectricity and use renewable hydrogen as key components to its operations. The first-of-its-kind plant will have a capacity of 200 kta and will use 100pc segregated green #propylene and #ethylene as feedstock to produce a wide range of #PP grades. With high-purity feedstock and proven technology, PP will serve as a direct drop-in replacement for fossil-based alternatives. The plastics produced will be fully traceable and #CO2negative , allowing customers to reduce their #Scope3 #emissions . Earlier this year, Vioneo and Honeywell announced that Honeywell’s advanced (methanol-to-olefin MTO) technology will be used by Vioneo to produce greenolefins for the comple...
