JEC World 2019 preview: Chomarat
Chomarat (Le Cheylard, France) is exhibiting its latest woven and multiaxial carbon fiber reinforcements at JEC World 2019.
According to the company, its C-WEAVE carbon fiber fabrics serve as a benchmark for surface-finish quality and processability for prepregs. The reinforcement, Chomarat says, contributes to productivity and reliability during the prepregging process. Advantages of multiaxial reinforcements include oriented axes, absence of resin-rich areas allowing a high fiber content and improved mechanical tensile and/or bending performance due to non-crimp fibers.
Chomarat’s C-PLY range has been developed to increase prepreg performance and appearance with minimum marking on parts and optimized surface quality through fiber spreading and the use of suitable stitches. C-PLY can also integrate aesthetic functions by using the assembly seam as a graphic design, Chomarat says. These new advantages, aimed at combining quality with productivity, are targeted for applications in the automotive, sports-equipment and consumer electronics markets.
Commercial production of recycled carbon fiber currently outpaces applications for it, but materials characterization and new technology demonstrations promise to close the gap.
Powerhouse manufacturer’s high-pressure compression molding process forms prepregged CFRP components with forged-metal properties.
The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.
