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。
In order to get the influence of the five process parameters of hot air gun temperature, laying speed, pressure roller pressure, pressure roller temperature and floor temperature on the flexural strength and interlaminar shear strength (ILSS) Continuous glass fiber reinforced polyphenylene sulfide prepreg tape layup molding experiment composite plate, orthogonal experiment and single factor experiment to study the law. The results show that the pressure roller exerts the most significant influence on the sheet metal ILSS, the bottom plate temperature has the least effect on the ILSS, and the placement speed has the greatest effect on the bending strength. The pressure roller temperature has the least effect on the bending strength. In the right range, reduce the laying speed, increase the pressure roller pressure, choose the right hot air gun temperature, floor temperature and pressure roller temperature, conducive to material bending performance and ILSS upgrade. Under the conditions of the car speed of 40 cm / min, the pressure roller pressure of 0.4 MPa, the pressure roller temperature of 240 ℃, the heat gun temperature of 340 ℃ and the floor temperature of 240 ℃, the interlayer of GF / PPS composites The shear strength and flexural strength reached the optimal values of 79.94 MPa and 1097.37 MPa, respectively.
