摘要
研制了用于ＵＨＭＰＥ纤维表面处理的连续化学处理装置。将经过处理的ＵＨＭＰＥ纤维与环氧树脂体系制备成复合材料。用复合材料的短梁剪切强度评价纤维处理效果。测定了复合材料的压缩性能、弯曲性能和冲击性能（包括平面冲击、缺口与非缺口冲击）。结果表明，ＵＨＭＰＥ纤维复合材料的韧性极好，虽然其刚度较低，压缩强度与弯曲强度较差。这种复合材料的失效模式主要是纤维与基体的脱粘、分层、纤维屈曲和大变形。
A device for the chemical treatment of fiber surface was designed and installed, with which UHMPE fibers were treated continuously. Unidirectional composites of treated UHMPE fiber/epoxy resin were manufactured. The short beam shear strength of the composites was measured in order to evaluate the effect of fiber treatment. The compressive, flexural and impact properties were also tested and the results show that this type of composites is extremely tough though its stiffnesses and strengths are lower than those of carbon fiber reinforced composites. The main failure modes of this material include debonding and delamination, fiber buckling and bending, instead of fiber breaking usually observed in carbon or glass fiber reinforced composites.
