Abstract The low velocity impact behavior of basalt/epoxy composites, seen as an eco-friendly replacement of glass-epoxy composites, has not been studied systematically so far. Here, the elastic elasto-plastic properties, strengths, intralaminar and interlaminar fracture energies were determined. The intralaminar energies were determined using compact tension and compression tests. The elasto-plastic properties needed in the plastic potential were determined using off-axis test. These properties are used in Finite Element (FE) code with an elasto-plastic damage model developed earlier to simulate the impact response of cross-ply laminates basalt/epoxy laminates. Low velocity impact (LVI) experiments at 10 J, 20 J and 30 J are performed on these composites. The FE simulation is successful in capturing force, energy, deflection histories and damage zones showing a close match to the experiments. A comparison of impact force history and damage area (ultrasonic C-scan) of basalt-epoxy laminates with glass epoxy laminates having same volume fraction shows nearly similar peak forces but the major axis of the ellipsoidal damage zone was bigger in glass/epoxy laminates.

低速冲击下交叉层玄武岩/环氧树脂层压板的非线性材料表征和数值模拟

摘要 玄武岩/环氧树脂复合材料的低速冲击行为被视为玻璃-环氧树脂复合材料的环保替代品，但迄今为止尚未进行系统研究。在这里，确定了弹性弹塑性特性、强度、层内和层间断裂能。使用紧凑拉伸和压缩测试确定层内能量。使用离轴测试确定塑性势所需的弹塑性特性。这些属性在有限元 (FE) 代码中使用，并使用较早开发的弹塑性损伤模型来模拟交叉层层压玄武岩/环氧树脂层压板的冲击响应。对这些复合材料进行了 10 J、20 J 和 30 J 的低速冲击 (LVI) 实验。有限元模拟成功地捕获了力、能量、偏转历史和损坏区域显示与实验密切匹配。玄武岩环氧树脂层压板与具有相同体积分数的玻璃环氧树脂层压板的冲击力历史和损坏面积（超声波 C 扫描）的比较显示出几乎相似的峰值力，但玻璃/环氧树脂层压板中椭圆形损坏区的主轴更大。
