Preparation and properties of polyethylene terephthalate/ polycar- bonate blending fibers through in-situ microfiber
Morphology and tensile properties of in-situ microfiber composite (MFC) based on polyethylene terephthalate (PET)/polycarbonate (PC) were studied in this article. The result showed that PET and PC were immiscible. But this property was beneficial to form PET microfibers. PET particles through “extrusion-hot stretching-quenching could form microfibers in PC matrix so as to improve the tensile properties of materials. The influence of PET mass content (Cm) on the number of PET microfibers and breaking strength of the blending fibers was studied at a fixed take-up speeding. It was found that the distribution of microfibers was homogeneous and the number of microfibers presented the maximum at Cm=30%. Tensile properties of the blending fibers showed similar change to the number of PET microfibers. Breaking strength and elongation at breaking of the blending fibers presented the maximum at Cm=30%.
