Chomarat Unveils Multiaxial Reinforcement for Thermoplastics at JEC World 2018

27 February 2018

Chomarat is launching a new glass multiaxial non-crimp fabric (NCF) for thermoplastic composites at JEC World.

The patented stitching yarn used can withstand processing temperatures to 400°C, making it an industrial solution for thermoplastic composites and an alternative to the woven reinforcements used, especially in the automotive sector. The company is also exhibiting a unidirectional carbon NCF reinforcement that is adapted to the productivity and performance requirements of the wind energy sector.

Reinforcing automotive thermoplastics

Thanks to its patented stitching yarn, the glass NCF reinforcement GPLY offers new possibilities in thermoplastic RTM and organosheet processes.

“This is an especially innovative solution, utilising stitching yarns that are compatible with processing temperatures to 400°C," explains Chomarat's Automotive Market Manager, Francisco De Oliveira. "These multiaxials improve performance and provide a lot of construction freedom in terms of fibre orientation. These new design possibilities contribute to structural optimisation. The quest for more lightweight vehicles, shorter cycle times and lower cost is a major issue for all builders.”

The new heat-stable G-PLY reinforcement can withstand very high processing temperatures without deformation and provides optimal mechanical performance.

Carbon UD for wind turbine structures

Chomarat is exhibiting an infusion-moulded laminate made with 150 plies of its new unidirectional carbon C-PLY. This 600 g/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," says Chomarat Wind Energy Market Manager, Raphaël Pleynet. "Increasing the blade length by incorporating carbon stiffeners increases power, and so it also lowers the cost of the energy.”

The carbon UD provides a solution to optimise the weight/power ratio. The UD’s high permeability reduces cycle times and lowers blade production costs.

Professor Sung Ha from the University of Hanyang will give a conference presentation on composite challenges in the wind energy sector at 11:30 am on Wednesday 7 March 2018 at JEC World.
