摘要
Abstract
Glass fiber reinforced resin composite materials in service is vulnerable to external impacts,which will cause composite structure damage,and thus severly threaten the safety service life of composite.In this paper,the improvement of impact resistance of glass fiber reinforced resin composite materials through coating a layer of polyurea elastomer was investigated.Charpy impact test machine,and optical microscopy were carried out on the specimens of no coating,front coating and back coating,respectively.The results show that the elastic deformation and fracture failure of polyurea coating can dramatically increase impact energy consumption and improve the impact strength of specimens.With the same thickness of coating,the coating of polyurea elastomer of front coating specimens does not completely fracture and absorb impact energy mainly through the elastic deformation,playing a buffer role.Conversely,the back coating specimens can absorb more impact energy due to fracture failure of polyurea coating,which will lead to lowest impact damage and higher impact strength.关键词
