玻璃纤维增强乙酸乙烯酯自然老化寿命预测研究

摘要

The natural aging samples of glass fiber reinforced vinyl acetate were studied to examine their tensile strength's trends.The natural aging life of glass fiber reinforced vinyl acetate samples of six regions was linear regression analysed, the linear regression equation was acquired, and the required time of tensile strength dropped to 50% was calculated.%对玻璃纤维增强乙酸乙烯酯的自然老化样品进行研究,考察了其拉伸强度的变化趋势.并对其自然老化寿命进行了线性回归分析,得到了6个地区的线性回归方程,计算出拉伸强度下降到50％需要的时间.
