JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2012 - The University of Applied Sciences and Arts in Dortmund shows a method for constructing CRP moulds that can be electrically heated.
The moulds are preferably intended for small- and medium-sized production runs. Because of their special structure, in which the CRP laminate assumes both the load-bearing and the resistance heating function, considerable energy and cost savings are possible. This system allows high heating and cooling rates, thus reducing cycle times as compared to other heated moulds. Due to the special arrangement of the materials, the moulds exhibit high dimensional stability during the manufacturing process despite the temperature variations. This leads to previously unachieved dimensional reliability, even for large components.
A new feature of these moulds is a nickel coating which provides the chemical and abrasion resistance needed for full production runs. Examples of applications are wind turbine rotors, ship hulls, interior cladding of aircraft and rail vehicles, moulded parts for medical technology, heightened roofs for transporters and trailers, and large-scale primary and secondary structures for a wide variety of applications.
