In this paper, an attempt has been made to numerically investigate the transient dynamic response of carbon-basalt/epoxy laminated composites subjected to low velocity impact. Carbon laminates are expensive hence, inclusion of cheaper basalt to obtain an improved, yet economical laminate is necessary. Finite element analysis (FEA) technique has been employed to simulate the laminated models. Loading profiles and test conditions from drop-weight tests have been obtained from literatures and necessary validation of FEA has also been performed. A correlation between impactor mass and velocity on the maximum laminate centre deflection has been established. In addition, the influence of hybrid stacking sequence and carbon position in the hybrid on laminate damage response has been studied. It has been observed from the study that hybrid 3 (H3) with stacking sequence CCBC-2 (best combination) showed the least deflection of all the stacking sequence sets and has the lowest deflection in all the low velocity impact testing conditions.

碳-玄武岩/环氧混杂层压板低速冲击的数值分析

在本文中，已经尝试数值研究碳-玄武岩/环氧层压复合材料在低速冲击下的瞬态动力响应。碳层压板是昂贵的，因此，需要包含更便宜的玄武岩以获得改进的但经济的层压板。有限元分析（FEA）技术已被用来模拟叠层模型。从文献中获得了落锤试验的载荷曲线和试验条件，并对FEA进行了必要的验证。已经建立了冲击器质量与速度在最大层压板中心挠度之间的相关性。此外，研究了混合堆垛顺序和混合物中的碳位置对层压板损伤响应的影响。
