摘　　要：复合材料的不断发展使其在航空航天等各个领域的工程应用越来越广泛,为了满足各领域进一步的发展需求,对复合材料的力学性能要求也逐渐提高。本文研究了碳纤维泡沫夹芯结构(材料牌号:W-3021FF/H60)在不同夹芯厚度和不同冲击能量下的损伤情况,采用超声C扫描对冲击损伤区域的深度与面积进行测量,最后通过试验和测试结果分析冲击能量与泡沫夹芯厚度对冲击损伤情况的影响。结果表明:泡沫夹芯结构的冲击损伤深度与面积和冲击能量正相关,并随着冲击能量的提高,损伤深度与面积的增长速率发生改变;泡沫夹芯的厚度越大,对冲击能量的展向引导能量越强,损伤面积越大,损伤深度越小。With the continuous development of composite materials,it has been widely used in aerospace and other fields.In order to meet the further development needs of various fields,the requirements for the mechanical properties of composite materials have gradually increased.In this paper,the damage of carbon fiber foam sandwich structure(Material designation:W⁃3021FF/H60)under different sandwich thickness and impact energy is studied.Ultrasonic C scanning is used to measure the depth and area of impact damage area.Finally,the impact of impact energy and foam core thickness on impact damage is analyzed by test and test results.The results show that the impact damage depth and area of foam sandwich structure is positively related to the impact energy,and with the increase of impact energy,the growth rate of damage depth and area changed;the larger the thickness of the foam core is,the span⁃direction guiding energy for impact energy,the larger the damage area and the smaller the damage depth.
