亚麻纤维增强环氧树脂基复合材料拉伸强度的预测模型
Tensile Strength Prediction Model of Flax Fiber Reinforced Epoxy Resin Matrix Composite
摘 要
采用真空辅助树脂传递模塑(VARTM)工艺制备了亚麻纤维增强环氧树脂基复合材料,研究了纤维体积分数对其拉伸强度的影响;通过对Kelly-Tyson拉伸强度预测模型进行修正,建立了亚麻纤维增强树脂基复合材料拉伸强度的预测模型,并计算了模型的预测精度.结果表明:当纤维体积分数为38.6%时,复合材料的拉伸强度最大,约为63.10 MPa;不同纤维含量的复合材料因界面剪切强度不同,其所对应的临界纤维长度、纤维拉伸强度及纤维长度效应因子均有所不同;建立的拉伸强度预测模型的预测精度约为97.8%.

Abstract
The flax fiber reinforced epoxy resin composite was prepared by the vacuum assisted resin transfer molding (VARTM) process,the effect of volume fraction of the fiber on tensile strength was studied.Kelly-Tyson tensile strength prediction model was modified and thus built a new tensile strength prediction model of the composite,and the prediction accuracy of the model was calculated.The results show that the tensile strength of the composite reached a peak (63.10 MPa) when the volume fraction of the fiber was 38.6%.The critical length of the fiber,the tensile strength and the fiber length effect factor were different because of the different shear strength.The prediction accuracy of the tensile strength prediction model was 97.8%.
