In this paper, high-performance thermotropic liquidcrystalline polymer (TLCP)/polypropylene (PP) and glassfiber (GF)/PP composites were prepared by the injectionmolding process. Mechanical recycling of TLCP/PP andGF/PP composites consisted of grinding of the injectionmolded specimens and further injection molding of thegranules. The influence of mechanical recycling onmechanical and thermal properties was investigated. In situTLCP/PP maintains tensile modulus and strength duringthe recycling process, indicating the regeneration ofpolymeric fibrils at each reprocessing stage. GF/PPcomposite exhibits deterioration of mechanical propertiesafter recycling because of fiber breakage during processing,which is a very common issue on reusing glass or carbonfiber reinforced composites. The experimental resultsreveal that the TLCP/PP composite has better recyclabilitythan GF/PP.

Ionic Monomer

The-NH2 groups, as grafting initiators, are introduced to the surface of meta-aramid fibers by treating the fiber surface with dilute sodium hydroxide solution. A kind of new aramid fibers liquid crystalline polymer were synthesized by interfacial polymerization of mesogenic monomer DDBA, main-chain LCI containing sulfonate ionic monomer BY, sebacoyl dichloride and aramid fibers hydrolysed. The structure and properties of aramid fibers before and after modification were characterized by SEM, FTIR, and POM.
