Chomorat has released two reinforcement fabrics; G-FLOWTM made of glass fibre, and C-PLYTM ULTRA THIN, of carbon fibre.
"G-FLOW is a 100% glass reinforcement fabric for the infusion process. It enables substantial cost savings without sacrificing on mechanical properties. To my knowledge, it is the only one on the market that combines structural and flow properties. This also applies to large parts, thanks to its good permeability and exceptional flow rate over long distances without the addition of an external flow medium," explained the Group’s General Manager, Michel Cognet.
Chomarat explains that the flow function is made possible by G-FLOW’s unusual textile structure. The integration of this function decreases the number of supply networks required, and it reduces the use of consumables and the processing time. It says the tests that were performed show that material costs dropped by 20-30% and that cycle times were 10% shorter compared to a solution requiring an external flow medium. They also demonstrated that the use of G-FLOW preserves the same tensile and flexural properties as for a laminate created using an external flow medium. "This is why it adapts just as well to the boating market as to wind energy or transportation, for example," said Cognet.
Chomarat is also introducing its new intermediate-modulus (IM) carbon fibre product, C-PLY ULTRA THIN. "Chomarat is pushing the technological envelope with this new areal weight of non-crimp fabric (NCF) carbon reinforcements, the most recent in our C-PLY line. The latest developments enabled the production of a biaxial with 50 gsm plies (for a total 100 gsm) made of IM carbon fibre. Besides its excellent mechanical performance and incomparable lightness, this reinforcement can be processed using RTM, infusion or prepregs, just like all the reinforcements in the C-PLY line," said Cognet.
Chomarat says it now supplies a non-crimp fabric in bi-, tri-, quadriaxial or UD, with 70 gsm plies made of IM carbon fibre (24K), and plans to industrialise its new biaxial prototype with ultra-thin plies (50 gsm) made of IM carbon fibre, starting in 2016.
