GFRP-槟榔杆复合构件基本力学性能试验研究
Study on basic mechanical properties of GFRP-areca palm stick composite members
摘要
Abstract
To enhance the utilization rate of local materials on tropical island and reduce island project con-struction costs and improve construction efficiency,this paper proposes a low-cost composite members form of GFRP-restrained areca palm stick and studies its basic mechanical properties.Through axial compression and four-point bending tests on 10 GFRP-areca palm stick composite member and 2 control specimens,the effects of differ-ent GFRP wrapping directions and layers on the failure mode,axial compression characteristics,and bending prop-erties of the elements were studied.The test results show that the axial compressive bearing capacity of the GFRP-areca palm stick composite member is increased by 110.28%to 925.18%compared to the control specimen,while the bending bearing capacity is increased by 92.20%to 1 063.42%.The single direction wrapping method makes the composite specimen lack fiber constraint in the uncovered direction,causing some composite specimens to have a failure mode similar to the bare pole.Only wrapping the longitudinal and transverse directions along the entire length can provide sufficient constraint for the GFRP-areca palm stick composite member,thereby changing the failure mode of the specimen and improving its mechanical properties.The research results will provide theoretical basis for the promotion and application of GFRP-areca palm stick composite member.关键词
