环氧树脂/蒙脱土纳米复合材料的动态力学性能研究
STUDY ON DYNAMIC MECHANICAL BEHAVIORS OF EPOXY/CLAY NANOCOMPOSITES
【摘要】 利用分离式Hopkinson压杆研究了环氧树脂/蒙脱土纳米复合材料在102~104/s高应变率范围下的动态力学性能。用三点弯曲试样的动态响应得到动态强度因子曲线,由曲线及裂纹起裂时间求出了不同蒙脱土含量试样动态断裂韧度。
【Abstract】 The dynamic mechanical properties of epoxy/clay nanocomposites are investigated at average strain rates of 10~2-10~4/s by the apparatus of SHPB in this paper. Dynamic stress intensity factor of K_id is obtained by the dynamic response of three-point bending specimen under the impact loads.
