Chomarat unveils new multiaxial glass NCF

The glass NCF reinforcement (G-Ply) developed by Chomarat is said to offer new possibilities in thermoplastic RTM and organosheet processes. © Chomarat Chomarat, a composite reinforcement specialist group, is launching its multiaxial glass NCF for thermoplastic composites at the upcoming JEC World, which takes place in Paris next week. The patented stitching yarn used can withstand processing temperatures to 400°C, making it an innovative industrial solution for thermoplastic composites and an alternative to the woven reinforcements used especially in the automotive sector, the company reports.

For the first time, Chomarat is also exhibiting a unidirectional carbon NCF reinforcement that is adapted to the productivity and performance requirements in the wind energy sector.

Innovative industrial solution

Thanks to a unique patented stitching yarn, the glass NCF reinforcement (G-Ply) developed by Chomarat is said to offer new possibilities in thermoplastic RTM and organosheet processes. “This is an especially innovative solution, utilizing stitching yarns that are compatible with processing temperatures to 400°C,” explained Francisco De Oliveira, Chomarat Automotive Market Manager.

“These multiaxials improve the performance and provide a lot of construction freedom in terms of fibre orientation. These new design possibilities contribute to structural optimization. The quest for more lightweight vehicles, shorter cycle times and lower cost is a major issue for all builders.”

According to the manufacturer, this new heat-stable G-Ply reinforcement can withstand very high processing temperatures without deformation and provides optimal mechanical performance.

Reinforcing wind turbine structures

For the first time, Chomarat is exhibiting an infusion-moulded laminate made with 150 plies of its new unidirectional carbon C-Ply. This 600g/m², high-permeability NCF can be used to create extra-thick structures, in particular the wind-turbine blade stiffeners, or spar caps.

“Cost reduction is the challenge in the wind energy industry. Increasing the blade length by incorporating carbon stiffeners increases power, and so it also lowers the cost of the energy,” said Raphaël Pleynet, Chomarat Wind Energy Market Manager. The carbon UD developed by Chomarat provides a solution to achieve the goal to optimise the weight/power ratio. The UD’s high permeability is said to reduce cycle times and lower the blade production costs.

Professor Sung Ha from the University of Hanyang will give a conference on composite challenges in the wind energy sector on 7 March 2018 at JEC World.
