摘要/Abstract

摘要： 研究了热老化温度和时间对碳纤维复合材料的拉伸、压缩和弯曲性能的影响,并对热老化的影响过程进行了分析。利用二元回归分析方法建立了碳纤维增强复合材料老化弯曲强度预测模型,并对模型显著性进行了检验。检验结果显示,预测最大相对误差仅为3.61%,预测精准度好,预测模型具有一定可靠性。

Abstract: The aging mechanical properties of composites is very important, so accelerated thermo-aging text on carbon fiber composites is performed at 110℃, 120℃, 130℃ and 140℃ temperatures for 300, 600, 900, 1200, 1600 and 2000 hours in this paper. It examines the influence of aging temperature and aging time on tensile strength, compress strength and bending strength of carbon fiber composites, and analyses the influence process. The experiment result indicates that bending property is more sensitive with the change of aging temperature and aging time than tensile property and compress property. At the last, the prediction model of CFRC bending strength is obtained base on the binary regression analysis, and the conspicuousness of model has been tested. The test result shows that the most relative error is only 3.61%, the prediction precision is very good, the model is credible in certain condition.

Key words: CFRC, aging, binary regression analysis, prediction, mechanical properties
