为了探究单向玻璃纤维复合材料(glass fiber reinforced polymer,GFRP)的性能,采用2种成型工艺制备了GFRP,并进行拉伸强度试验,测定了GFRP的极限强度,研究成型工艺对其拉伸强度的影响。对传统单向纤维复合材料拉伸强度预测模型进行了改进,提出了基于纤维强度服从正态分布的单向纤维复合材料纵向拉伸强度预测模型。试验结果与模型预测结果对比表明,所提出的预测模型具有良好的精度。 In order to investigate the properties of GFRP, GFRP was prepared by two molding processes and tested for tensile strength. The ultimate strength of GFRP was measured and the tensile strength Impact. The prediction model of tensile strength of traditional unidirectional fiber composites was improved, and the prediction model of longitudinal tensile strength of unidirectional fiber composites based on normal distribution of fiber strength was proposed. The comparison between the test results and the model predictions shows that the proposed prediction model has good accuracy.
