EXPERIMENTAL STUDY ON INTERFACE PERFORMANCE OF GFRP COMPOSITE SANDWICH COLUMN WITH WOOD-PLASTIC COMPOSITE CORE
摘要
Abstract
Fibre reinforced polymer (FRP) composite sandwich column which composed of FRP sheets and wood-plastic composite (WPC) core were manufactured using vacuum infusion molding process with wood-plastic composite,alkali-free glass fiber bundle and unsaturated resin.The effects of the WPC core on load-bearing capacity,the failure mode and load-strain curve were investigated using axial compressive tests.The results showed that a failure of axial strength and transverse cracks occurs in the composite sandwich column under axial pressure.The ultimate bearing capacity of the composite sandwich column under axial pressure is related to section size of the column,which is raised with the size.In addition,the lateral deformations of the composite sandwich column is greatly constrained by FRP,so the ductility can be improved.A formula of ultimate bearing capacity of the composite sandwich column was deduced and the predictions of the formula agree well with the test data when the value is 0.3.关键词
