摘要
针对先进复合材料树脂膜渗透成形技术(RFI)中的树脂膜,分析了其成形的基本过程,在测定树脂体系的基本粘度-温度关系基础上,采用树脂膜/离型纸的拉伸剪切实验方法测定了树脂膜的拉伸剪切强度,研究了树脂膜在不同温度及速度下的剪切载荷-位移关系及内聚破坏及界面破坏的转变温度范围。结果显示,破坏形式的转化是决定剪切强度-温度依赖性的关键。确定了实验树脂体系的成膜工艺区间的下限。
The manufacturing processing of resin film used in resin film infusion technology was briefly analyzed. Based on the measurement of viscosity-temperature relationship of resin systems, tensile sheer test was conducted to investigate the transition temperature range from cohesion failure to interface failure, and shear load-displacement behavior. The results showed that the transition of failure behavior from cohesion to mixture or interface was the key which dominated the relationships between shear strength and test temperature. The temperature lower limit for the resin film manufacturing was determined by results of tensile sheer test.
