摘　　要：研究了玻纤增强聚丙烯(GFPP)复合材料的超声波焊接工艺,重点探索了焊接能量及超声振幅对GFPP复合材料接头剪切强度的影响。研究表明:随着焊接能量及振幅强度的增加,GFPP复合材料接头剪切强度均出现先增加后降低的趋势,在70%振幅及20J焊接能量下,接头剪切强度可达25MPa,接近母材PP树脂拉伸强度。The ultrasonic welding process of glass fiber reinforced polypropylene(GFPP)composite was studied,the effects of welding energy and ultrasonic amplitude on the shear strength of GFPP composite joints were emphatically explored.The results have shown that with the increase of welding energy and amplitude strength,the shear strength of GFPP composite joints first increases and then decreases.At 70%amplitude and 20J welding energy,the shear strength of the joints can reach 25MPa,which is close to the tensile strength of the PP resin matrix.
