基于动态高分子基复合材料的一体化T型加筋壁板力学性能仿真研究
Simulation on mechanical performance of integrated T-shaped reinforced wall panel based on carbon fiber reinforced dynamic polymer composites
摘要
Abstract
The prepreg tape with dynamic reversibility and excellent mechanical properties were prepared by using bi-sphenol-A diglycidyl ether as a resin matrix,glutaric anhydride as a curing agent,carbon fiber as a reinforcement.The tensile,compressive,bending,stress relaxation,and creep properties of the composites after hot pressing were investi-gated.According to The mechanical test results,the solid modeling was conducted for the secondary bonding forming and integrated forming structure panel,and a finite element simulation analysis was carried out.The results indicated that compared to the traditional secondary bonding forming structure panel,the maximum deformation of the integrated forming structure panel decreased by 28.57%,28.57%,28.04%and 8.27%under tension,compression,bending,and impact conditions,respectively,at the same external load.When buckling instability occurred,the critical load of the integrated structure panel increased by 84.69%,and its longitudinal strain at the maximum deformation at each an-gle was greatly improved,demonstrating excellent anti-buckling performance.关键词
