<scp>Polypropylene/</scp> poly(ethylene terephthalate) microfibrillar reinforced composites manufactured by fused filament fabrication

In the present work, microfibrillar composites (MFCs) consisting of polypropylene (PP) and poly(ethylene terephthalate) (PET) were successfully produced by melt extrusion cold stretching. The resulting filaments then printed using fused filament fabrication. morphological results demonstrate that highly oriented PET fibrils after stretching are still well preserved in components. Since printing process defines alignment final component fibers can be perfectly adapted to load paths. Comparative analyses mechanical properties reveal act as an effective reinforcement 3D components, superior performance PP/PET MFCs compared a blend neat PP. Due combination material innovative processing, study opens up new way morphology-based enormous potential polymer for lightweight, cost-effective recyclable full solutions compact
