摘要
本文在总结了不连续纤维复合材料在纤维单向分布和随机分布的情况下其弹性模量估算方法的基础上,针对离心浇铸不连续纤维的取向特点,提出了分析离心浇铸纤维复合材料弹性模量的复合层板模型。在确定了离心浇铸纤维方向分布函数g(θ)后,利用由最大能量强度准则建立起来的不连续纤维复合材料强度计算公式预报强度。试验结果与计算结果较为吻合。
Based upon summarizing the calculating methods of the elastic mouldus of unidirectional and random discontinuous fibre RP, this paper analy-sesthe fibre orientation in centrifugally cast discontiauous fibre RP and put forward a mixed modei for calculating the elastic modulus of the composites. Determining the probability density function g (9) respect to fibre orientation, we can predict the values of strength of centrifugally cast discontinuous fibre RP with the method applying the maxmum energy strength criterion. The predicted values are coincided with the experimental results.
