摘要/Abstract

摘要： 为得出铺放成型过程中热风枪温度、铺放速度、压力辊压力、压力辊温度和底板温度五个工艺参数对复合材料板材弯曲强度和层间剪切强度(ILSS)的影响,用自制连续玻璃纤维增强聚苯硫醚预浸带进行铺放成型实验制备复合材料板材,分别用正交试验和单因素实验研究其规律。结果表明,压力辊压力对板材ILSS影响最大,底板温度对ILSS影响最小,铺放速度对弯曲强度影响最大,压力辊温度对弯曲强度影响最小。在合适的范围内,降低铺放速度,升高压力辊压力,选择适中的热风枪温度、底板温度和压力辊温度,有利于材料弯曲性能和ILSS的提升。在铺放小车速度为40 cm/min、压力辊压力为0.4 MPa、压力辊温度为240 ℃、热风枪温度为340 ℃和底板温度为240 ℃的条件下,GF/PPS复合材料板材的层间剪切强度和弯曲强度达到最优值,分别为79.94 MPa和1097.37 MPa。

Abstract: Orthogonal experiments and single-factor experiments were carried out to evaluate the effects of five processing parameters including temperature of hot air, tape laying speed, pressure of roller, temperatures of roller and platform on interlaminar shear strength (ILSS) and flexural strength of the laminates to get optimal parameters in tape placement process. The prepreg made of polyphenylene sulfide as matrix and continuous glass fiber as reinforcement was used. The results show that the pressure of roller has significant impact on ILSS and the temperature of platform has less impact on ILSS, while the tape laying speed has significant impact on flexural strength and the temperature of roller has less impact on flexural strength. Besides, higher ILSS and flexural strength can be achieved by improving the tape laying speed and pressure of roller properly and choosing the temperature of hot air, temperature of platform and temperature of roller in the suitable range for operation. When the optimal condition of the tape laying speed is 40 cm/min, the pressure of roller is 0.4 MPa, the temperature of roller is 240 ℃, the temperature of hot air is 340 ℃ and the temperature of platform is 240 ℃, ILSS and flexural strength of the laminate can reach 79.94 MPa and 1097.37 MPa, respectively.

Key words: continuous glass fiber, polyphenylene sulfide, tape placement, interlaminar shear strength, flexural strength
