摘要/Abstract

摘要： 纤维增强树脂基复合材料泡沫夹芯管在较少提高承压试件重量的前提下较大地提高了承压试件的稳定性。为进一步了解设计参数对复合材料泡沫夹芯管轴压力学性能的影响,对四组复合材料泡沫夹芯管试件进行了轴压静载试验。结果表明,复合材料内外管纤维铺层组合对夹芯管轴压极限承载力及破坏模式有很大影响;不同的纤维铺层组合可使夹芯管的破坏模式由脆性破坏转为延性破坏;聚氨酯泡沫芯层密度在0.15~0.45g/cm³时对夹芯管轴压极限承载力的影响不大,通过试验得到了不同设计参数对复合材料泡沫夹芯管的轴压极限承载力的影响规律。

Abstract: Fiber-reinforced resin composite-foam sandwich pipe have better local flexural rigidity compared to the composite thin-walled tube. It had improved the local stability of the composite tubes greatly while weight increased less, which was similar to reinforcement ribs, thus giving full play to the strength of the material. In order to investigate the composite foam sandwich tube′s axial compressive performance of the different design parameters, the axial compressive experiment was studied in this paper. The results show that the fiber plies combination of the resin matrix composites foam sandwich tube has greater influence on the axial compressive performance and the different fiber ply combination can lead specimen damage from brittle failure to ductile failure. While the density of foam core layer has little influence on the ultimate axial compressive strength as it from 0.15g/cm³ to 0.45g/cm³. The paper gives the influence law of the different design parameters on the ultimate bearing capacity of the FRP-foam sandwich tube.
