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.
The Fraunhofer Institut introduces a process for automated production of complex dry textile preforms by local adhesive application.
Liquid Composites Moulding (LCM) processes such as RTM require rapid and cost-efficient manufacturing of complex dry textile preforms. In particular, concerning the medium and high volume production required for the automotive and mechanical engineering industry, the preform production is a major issue for manufacturing high-performance composite parts with LCM technologies.This issue has been addressed using chemical stitching approach and combines the advantages of the existing preform technologies such as binding and stitching, therefore offering a high potential for high-volume production of complexe LCM parts.Benefits of chemical stitching include:
