Dynamic mechanical properties and damage characteristics of satin weave carbon fiber fabric resin based composite material
摘要
Abstract
The dynamic mechanical properties of satin weave carbon fiber fabric resin based composite material Q/2AJ1011 in the warp and weft directions are studied using a split Hopkinson pressure bar(SHPB)experimental device at six temperatures ranging from-55℃to 75℃and three strain rates.The damage characteristics are studied using scanning electron microscopy.The results show that the material exhibits significant temperature sensitivity under dynamic compression.The compressive strength of the fiber at three strain rates in the warp direction and at high strain rates of 1250 s-1 in the weft direction is basically affected by temperature changes,with 25℃as the peak point of compressive strength,it decreases with the increase of temperature,and the decrease ratio reaches 18%with the increase of temperature to 75℃.As the temperature decreases to-25℃,the compressive strength of the material shows a decreasing trend,with a decrease ratio of 23%at-25℃.As the temperature further decreases to-55℃,the compressive strength significantly increases;However,the fiber weft direction exhibits a hysteresis phenomenon in the temperature effect at lower strain rates of 850 s-1 and 1100 s-1,with 50℃being the maximum strength.At the same time,it is found that intrinsic brittle materials exhibit certain elastic-plastic deformation at high temperatures.The material strength is not sensitive to changes in strain rate,and the performance changes are within 10%.The damage characteristics are greatly influenced by temperature and strain rate,with an increase in strain rate leading to a significant increase in shear.The influence of temperature results in a clear brittle fracture feature of concentrated through layered cracks at low temperatures,while an increase in debonding at high temperatures indicates a weaker interfacial bonding.关键词
