铺放成型工艺参数对复合材料板材弯曲强度和层间剪切强度的影响
STUDY ON PROCESSING PARAMETERS OF TAPE PLACEMENT FOR CONTINUOUS GF REINFORCED PPS
摘要
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.关键词
