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.
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.
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
