RESEARCH ON AXIAL COMPRESSION PERFORMANCE OFFIBER-REINFORCED FOAMED URETHANE SHORT COLUMNS

Abstract

Abstract: Fiber-reinforced Foamed Urethane (FFU) short columns are made of rigid polyurethane resin foam reinforced with glass fiber yarn bundles and manufactured by pultrusion. In order to study the axial compression performance of FFU short columns with different densities, three groups of FFU short columns with different densities were subjected to static axial compression tests and compared with ordinary concrete columns and steel columns. The test results show that the high- and low-density FFU short columns have different axial compression failure modes. As the density increases, the ultimate bearing capacity, initial stiffness and resistance to deformation will increase. However, the ductility of the specimen will decrease. FFU column has the characteristics of light weight and high strength. Under the same bearing capacity, the mass of FFU short columns is only 1/7 of reinforced concrete columns and 1/3 of I-shaped steel columns.

Key words: polyurethane, fiber-reinforced, short column, axial compression performance, composites
