玻璃纤维复合材料构件抗压性能研究
Research on compression performance of glass fiber composite material
摘要
Abstract
Glass fiber reinforced plastic material is widely used in the transmission line tower structure,but the factors in determining its performance and quality are complex,and the lack of related structure research brings certain influence.Through the axial compressive test of glass fi-ber reinforced plastic material and steel casing composite member,the axial compressive mechani-cal properties and failure mode of glass fiber composite component are studied in this paper;Based on the strength theory of transversely orthotropic material,finite element method is used to analyze the influence of eccentricity ratio and diameter-thickness ratio on glass fiber composite component.Results show that brittle failure occurs in glass fiber composite component,and the failure mode is oblique fracture in the node,and the maximum stress of glass fiber composite component is less than the compressive strength of material,so that reduction should be consid-ered in engineering design;Steel casing remains in the state of elastic stress.The ultimate bearing capacity of eccentric compression member decreases with an increase in eccentricity ratio,and the decrease extent reduces gradually;The reduction of diameter-thickness ratio can improve the ulti-mate bearing capacity of components;when diameter-thickness ratio decreases by 20%,ultimate bearing capacity will increase by 20%.关键词
