Research on Preparation and Mechanical Properties of Continuous Fiber Reinforced Polyethylene Impregnated Tapes

Abstract

The continuous fiber reinforced polyethylene impregnated tapes were prepared by a continuous fiber impregnated mould and a corresponding assembly line for the tapes, with polyethylene and glass fiber used as the main raw materials. The effects of fiber preheat temperature and the size of die on the tensile strength and content of the glass fibers were studied. The results show that suitable preheating temperature and die size were conducive to the increase of the tensile properties of composites. The crystallization behavior of the composites and their base resin was researched by a differential scanning calorimetry (DSC). The results show that, the crystallization temperature of the composites is significantly higher than that of the matrix resin.
