摘要：
A GFRP-light wood sandwich beam(GWSB) was designed. A corresponding pultrusion process for the GWSB was proposed. Alkali-free glass fiber, paulownia wood and unsaturated polyester resin were selected to manufacture GWSB. According to three-point bending test, the flexural performance and failure mode of GWSB were investigated. The results show that GWSB has a better elastic property and bearing capacity. Compared with paulownia wood beam and pultruded GFRP pipe, the bearing capacity is increased by 17.4 and 4.1 times, and the bending stiffness is improved by 12.8 and 1.7 times. GWSB can make good use of both GFRP and paulownia wood materials. ©, 2015, Tongji University. All right reserved.
