摘要
本文使用碳纤维单向织物与碳纤维、玻璃纤维及碳/玻混杂三向织物,制备了6种不同碳/玻混杂比三向织物复合材料层合板。选用18 J与28 J的冲击能量,对这6种复合材料层合板进行低速冲击试验,通过目视测量得到了冲击正反面的表面损伤,并利用超声C扫设备获取了试样内部的总体损伤面积,再结合冲击响应曲线,分析了碳/玻混杂三向织物复合材料层合板冲击过程的损伤机理。结果表明:在低冲击能量下,U_(C6)(TG)冲击过程中最大位移增长最大,为11.4%,U_(C6)(TC)的吸收能量提升最大,为7.6%;在高冲击能量下,U_(C6)(TG)冲击过程中最大位移增长最大,为15.9%,U_(C6)(TCCG)的吸收能量提升最大,为33.4%。碳/玻混杂三向织物复合材料层合板存在90°方向为长轴的类椭圆形与类圆形两种损伤形态。
In this paper,six types of carbon/glass hybrid triaxial woven fabric composite laminates with different carbon/glass mixing ratios were prepared using carbon fiber unidirectional fabrics and carbon fiber,glass fiber and carbon/glass hybrid triaxial woven fabrics.The impact energies of 18 J and 28 J were chosen to carry out low-velocity impact experiments on these six kinds of composite laminates.The surface damage on the front and back sides of the impact was obtained by visual measurement,and the overall damage area inside the specimen was obtained using ultrasonic C-scanning equipment,which was combined with the impact response curves to analyze the damage mechanism of the impact process of carbon/glass hybrid triaxial woven fabric composite laminates.The results show that at low impact energy,the maximum displacement growth during the impact of U_(C6)(TG)is the largest,with a growth value of 11.4%,and the absorbed energy of U_(C6)(TC)is the largest,with an enhancement of 7.6%;at high impact energy,the maximum displacement growth during the impact of U_(C6)(TG)is the largest,with a growth value of 15.9%,and the absorbed energy of U_(C6)(TCCG)is the largest,with an enhancement of 33.4%.Two damage patterns,ellipsoid-like and circular-like,existed in carbon/glass hybrid triaxial woven fabric composite laminates with 90°direction as the long axis.
