摘　　要：为满足车载深冷高压储氢气瓶对复合材料层的层间性能要求,使用短纤维插层的方法改善树脂基碳纤维复合材料拉伸性能,并通过添加不同种类与含量的短纤维探究短纤维增强拉伸性能机理。试验证明,纤维直径较小的玻璃纤维能够通过桥联作用使碳纤维复合材料拉伸性能有较大提升。In order to meet the interlayer performance requirements of the composite material for vehicle-mounted deep-cooled high-pressure hydrogen storage cylinders,the tensile properties of resin-based carbon fiber composites are improved by means of short fiber intercalation,and the mechanism of tensile properties of short fiber reinforcement is investigated by adding different types and contents of short fibers.It is demonstrated that glass fibers with smaller fiber diameters could improve the tensile properties of the carbon fiber composites through bridging action.
