摘要
为探究液体模塑成型过程中合模时碳纤维平纹织物与模具之间的摩擦行为,通过响应面分析法,结合自主设计的摩擦试验装置,研究织物层数、摩擦速度、加载力、磨头曲率及其交互作用对碳纤维织物表面摩擦力的影响。结果表明:织物层数的增加伴随摩擦速度的同步减小,可导致摩擦力逐渐增大,但其增长幅度仅为9%~11%;而磨头曲率的减小伴随加载力的同步增大会引起摩擦力的显著增大,其涨幅可达16%~33%;加载力的增大会导致纬纱损伤程度增加。该结果可为优化液体模塑成型工艺提供参考依据。
In order to explore the friction behavior between carbon plain weave fabric and tool during mold closing of liquid composite molding process,the interaction between fabric layer number,friction speed,normal load and tool curvature on the friction force were studied by response surface analysis.The results show that the interaction between the number of fabric layers and the friction speed,normal load and tool curvature have a certain influence on the friction.As the number of fabric layers increases and the friction speed decreases,the friction force increases gradually,but the increase amplitude is limited.When the tool curvature decreases,and normal load increase synchronously,the friction force increases gradually,and the increase trend of friction force is significant.The increase in loading force causes increased weft damage.The results provide a reference for optimizing the liquid molding process.
