混杂复合材料层合板抗冲击性能研究
Research on Impact Resistance of Hybrid Composite Laminates
摘要
Abstract
In order to investigate the structural safety of composite laminates due to impact loads in practical applications,the influence of the impactor shape on the damage mechanism of composite laminate was analyzed simultaneously by experiment and simulation.Subsequently,the variation pattern of the load-bearing capacity and energy absorption of the laminate was further revealed considering different impact energy.The results show that under same impact energy,the damage range and bearing capacity of laminates present incremental change when impacted by conical,hemispherical and flat impactors.The critical penetration energy of laminates increases along using conical,hemispherical and flat impactors.The impactor shape and the impact energy have a greater influence on the energy absorption capacity of laminates.关键词
