Potential utilization of recycled PET in comparison with liquid crystalline polymer as an additive for HDPE based composite fibers: Comparative investigation on mechanical performance of cross-ply laminates

Recycled polyethylene terephthalate (rPET) was used as an alternative reinforcing material for in situ microfibrillar-reinforced polyethylene (PE) based composite fibers and compared with liquid crystalline polymer (LCP). The neat PE and its composites reinforced with LCP and rPET microfibrils under...
