Hoog performante duurzaamheid met bio-gebaseerde epichlorohydrin.
Dit artikel gaat over de bioresin die twee van onze partners samen ontwikkeld hebben en die zijn eerste toepassing in onze 6e zonnewagen vond. Een resin wordt gebruikt om de vereiste eigenschappen van de carbonvezels te krijgen bij de productie van de wagen.

Success in resins and composites
In 2015, Epicerol®-based epoxy resins were used in the composite matrix of a Belgian solar car (Figure 3). The Punch One car combined the latest bio-based chemistry, solar panel innovation and electronic battery technology. The car competed and finished the Solar Challenge across Australia during October 2015, clearly putting Epicerol® through its paces.
Led by university students and experts, the Punch Powertrain Solar Team used an autoclave cure process to produce the car’s bio-based composites. These were produced using carbon fibre prepregs impregnated with BisA epoxy and cured with a hardener based on cashew nutshell liquid (CNSL), a natural renewable chemical raw material. The final resin matrix was calculated to contain 45% biomaterial.
In addition to a strong, impact-resistant, lightweight carbon fibre-reinforced epoxy car body, the excellent wetting properties of CNSL-based hardeners and the improved interlaminar shear strength of the final composite resulted in an overall bio-based content of 18%.
In light of these successes and its continued commercial development, Epicerol® received the Innovation Award in the Raw Materials category at JEC Asia 2015. The chemical was awarded and recognised as: Bio-based ECH for more sustainable epoxy resins. "
