Demonstrator bonnet panel for a race-bred supercar
Demonstrator bonnet panel for a race-bred supercar
Retrac Group, whose composites division is one of the UK’s most experienced composites engineering companies across motorsports, automotive and aerospace, recently used Evopreg® ampliTex™ + powerRibs™ to produce a demonstrator bonnet panel for a race-bred supercar under an R&D project.
The bonnet demonstrator is a two-part moulding, with both inner and outer produced using Evopreg® ampliTex™ EPC300-F300T 2×2 twill prepreg, backed with powerRibs™. The air duct components were 3D-printed at Retrac, using their Stratasys Fortus 450MC machine. Bonded using polyurethane adhesive to minimise A-surface witnessing, the whole assembly weighs just 4 kg.
Evopreg® ampliTex™ prepregs combine Composites Evolution’s high-performance Evopreg® epoxy resin systems with Bcomp’s award-winning ampliTex™ flax reinforcements, to deliver a family of materials which offer outstanding performance for component applications.
To reach the full performance of natural fibres, Evopreg® ampliTex™ prepregs have been tailored to be compatible with Bcomp’s powerRibs™ reinforcement grid, enabling the same stiffness and weight as thin-walled monolithic carbon fibre parts while decreasing the CO2 footprint by 85% and improving safety thanks to a blunt braking behaviour without dangerous debris or sharp edges.
What our client said...
We’re seeing a growing interest in flax fibre composites, particularly in the motorsports and niche vehicle sectors. It is therefore essential that we have developed an in-depth understanding of the processing requirements and performance capabilities of these materials, and are ready to respond to our customers' requirements. Being able to tap into the combined expertise and experience of both Composites Evolution and Bcomp is proving invaluable. Our laminators found the Evopreg ampliTex™ materials very easy to use, with good drape and tack to the moulds. The finished part looks great, and we shall showcase it later in the year
