Composite reinforcements specialist Chomarat Group is finalist in the JEC Innovation Awards in the Maritime Transportation & Shipbuilding category. Chomarat developed G-FLOW 980L, a structural flow media with 100% glass fibre for use in boat production using the resin infusion process, in collaboration with Groupe Beneteau.

“The challenge was to develop a fabric with high permeability in all directions that can be integrated into the structure of large composite parts without damaging their mechanical characteristics, while reducing infusion process costs. And we succeeded, thanks to our collaborative work and long-term partnership with Groupe Beneteau team,” explains Claude Chabal, Product Manager at Chomarat.

The result was an innovative design which is said to bring unprecedented flow performance and superior mechanical properties.

Towards greener composite materials

In addition to light weighting, the use of G-FLOWTM reinforcement in the resin infusion process reduces the impact on health and the environment, through a reduction in consumables and waste, Chomarat says - 50% fewer consumables used for resin supply networks compared with previous solutions and a 7% reduction in resin consumption, offering better cycle time as well as labour and material costs savings.

Additionally, G-FLOWTM can replace any flow media in large-scale parts using the resin infusion process for the same mechanical properties, offering two products in one.

“G-FLOWTM 980L meets all our expectations - isotropic permeability, mechanical performance and overall cost savings,” adds Damien Barre, Head of Project for composite materials R&D at Groupe Beneteau.

Increasing the use of the infusion process

With this new solution, Chomarat says it facilitates and reduces the costs of large composite parts using the resin infusion process and thereby helps to develop the use of infusion with these specifications. “Closed mould and particularly infusion process ensure a better part consistency and repeatability and provide better working conditions,” says Vincent Cholvy, Marine Market Manager at Chomarat.

G-FLOWTM, a patented solution by Chomarat, has been used in more than 500 boats (15 models) since 2018 and can be applied to different parts and new ranges.

“We hope to win this award, as it represents true recognition from the profession for our innovation,” Vincent Cholvy concludes.

Meet Chomarat’s teams and discover G-FLOWTM 980L at JEC World 2020 in hall 5 , stand j42 from 3-5 March, Paris Nord Villepinte.
