Hollow HP-RTM Carbon Fiber Parts
Hennecke along with several partners has developed a process to produce high geometry hollow HP-RTM parts with epoxy or PU resin systems along with woven or sheet carbon fiber material. The process uses a sand core that can withstand pressures up to 200 bar and is held together by a binder. This binder is eco-friendly and can be flushed out with regular water and without any use of solvents. Even better the core material is 98% recyclable. The process allows the reduction in both weight and total number of parts needed. This method of process can be implemented into many other integral manufactured fiber composite hollow parts like roof structures, structure leading constructions or even monocoque geometries. All of these benefits with a cycle time of just over to 2 minutes. With multi cavity tools per part cycle times of hollow HP-RTM parts can be well under 1 minute.
