Reinforced and toughened PP/PS composites prepared by Fused Filament Fabrication (FFF) with in-situ microfibril and shish-kebab structure Universiteit Gent
In this work, in-situ microfibrillar composites (MFC) of polypropylene (PP)/polystyrene (PS) were produced by Fused Filament Fabrication (FFF) with a self-designed build platform. Due to the high shearing and stretching effect during the FFF process, PS phase underwent a large deformation. A large number of PS microfibrils could be observed in the samples. Meanwhile the molecular chain of PP was also stretched and arranged along the flow ...
