一种短切碳纤维增强塑料强度的预测方法
A Method of Strength Forecast on the Plastic Reinforced by Short Carbon Fibers
摘 要
高性能纤维增强的先进复合材料中,短切碳纤维增强塑料因在性能上的多面性及较低的制作成本而极具吸引力.综合前人的研究成果推导了短纤维增强复合材料的强度混合法则公式,并用纤维长度效应来修正短纤维复合材料中的轴向应力分布的不均匀性,建立模型来正确估计各种参数对强度的影响规律.以短切碳纤维增强PTFE复合材料为例说明强度预测的正确性,为新材料的应用及新型结构的设计提供了依据.

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.
