Implementation of TP composites - short- and long-fiber compounds

Short-fibre thermoplastic composites (TP) represent a product family at the boundary between plastics, and in particular (non-reinforced) thermoplastics and composites, in that they use mass-produced plastics manufacturing (compounding by extrusion/granulation) and processing (injection) technologies, while at the same time offering high mechanical and thermal properties thanks to the presence of a high level of reinforcement.

Within the family of long-fibre TP compounds and sheets, it is now possible to define three products divided into two families:

• families of reinforced thermoplastic stampable sheets (TRE) ;

• the long-fibre compound (LFT) family, i.e. DLFT (direct LFT) and GLFT (LFT granules).
