At JEC Europe 2015, Chomarat (Le Cheylard, France) announced two new reinforcements: G-FLOW glass fiber fabric for infusion, which combines structural and flow functions, and the latest product in the C-PLY line, C-PLY ULTRA THIN, which the company claims is the first noncrimp fabric (NCF) made with ultra-thin intermediate-modulus (IM) carbon fiber plies at a very low areal weight of 50 g/m2 per ply.

G-FLOW reportedly offers good permeability and resin flow rate over long distances without the addition of an external flow medium. Its flow function is made possible by an unusual textile structure. The integration of this function reduces the number of resin supply lines required, use of consumables and processing time. Testing shows material costs dropped by 20-30% and cycle times were 10% shorter compared to a system using external flow medium. It also demonstrated that use of G-FLOW preserves the same tensile and flexural properties as for a laminate infused using an external flow medium. Chomarat believes the material will adapt equally well to marine, wind energy and transportation applications.

With C-PLY ULTRA THIN, Chomarat claims it is pushing the technological envelope by enabling the production of a biaxial NCF with 50 g/m2 plies (for a total 100 g/m2) made of IM carbon fiber. Reportedly offering excellent mechanical performance and hard to match lightweight, this reinforcement can be processed using RTM, infusion or prepregs, like all products in the C-PLY line. Developed for the sports and leisure sector, C-PLY ULTRA THIN is also suitable for the automotive industry. Chomarat now supplies NCF products in bi-, tri-, quadriaxial or unidirectional (UD), with 70 g/m2 plies made of IM carbon fibre (24K), and plans to industrialize this new biaxial prototype with ultra-thin plies (50 g/m2) made of IM carbon fibre, starting in 2016.
