|Summary||In this paper recent research on the hot compaction process developed at Leeds University is presented. In this process, thick section homogeneous sheets of fibre composites are produced by melting a thin skin on the surface of each fibre, which on cooling recrystallises to bind the structure together to produce a consolidated, single material, composite. For automotive applications, hot compacted sheet based on polypropylene (PP geotextile fabrics) shows an excellent combination of mechanical properties, especially low temperature impact strength. A range of weave styles and cloth weights have been compared and properties such as thermal expansion and high temperature creep studied. A comparison with isotropic random mat short glass fibre reinforced PP and Twintex unidirectional glass fibre will be presented.
