Thermoplastic pre-preg lines make use of a polymer system that has reoccurring plasticity with heat. The polymer can be heated and reheated multiple times, and typically flows as a liquid when hot. The use of thermoplastics in composites is less wide-spread than thermoset polymers & resins. Thermoplastics are seen as a lower cost, higher production rate alternative to the traditional thermoset pre-pregs, particularly given that thermoset pre-pregs, β-stage materials, have a limited shelf life, require temperature controlled storage, and contain hazardous/noxious materials.
Thermoplastic pre-pregs generally have:
|Product Width||6″ (150mm) wide to 70″ (1780mm) or greater|
|Temperature||Up to 450C (850F)|
|Materials||Fibre Glass, Carbon, Aramid|
|Polymer||PEEK, PPS, Nylon, PP, PES|
|Various forms of polymer (film, pellet, powder, fillet, liquid) can be applied|
Cygnet Texkimp maintains both thermoset and thermoplastic testing lines at its research and development laboratory. This pilot laboratory equipment is available for use by our clientele to enable their process/product developments and process evaluations.
Thermoset is a pre-preg option that is more commonly used in industry and is an alternative Thermoplastic pre-prefs.
