摘要: 在分析单向连续纤维增强复合材料纵向拉伸时细观受力与变形的基础上,对连续纤维的长度和方向进行尺寸和方向性修正,给出了短切纤维增强复合材料的拉伸强度预测公式.使用这个预测公式计算短切碳纤维增强PTFE复合材料的拉伸强度,预测值与实验值吻合得较好

Abstract:Among the advanced composites reinforced by high-performance fibers, the plastic reinforced by short carbon fibers is remarkable by its variety of performance and lower cost. By synthesizing the preceding productions, the strength rule-of-mixture of short fiber reinforced composite is educed, and the modified formula is obtained by using the length coefficient to correct the asymmetry of stress distribution in material. The math model is established to estimate the influence disciplinarian on strength of parameters. By taking carbon fiber reinforced PTFE composite as the example, the strength forecast method is explained, and it will provide the reference to new material usage and new structure design.
