摘要
通过二维编织-树脂传递模塑(RTM)成型方法制备得到了复合材料管,并设计制造特殊夹具,参考 GB/T 5350—2005及SY/T 7318.3—2017标准对复合材料管的弯曲及轴向压缩性能进行了研究,并参照实验结果与典型6061铝合金的力学性能进行了对比。结果表明:复合材料管的轴向压缩破坏形式均表现为脆性剪切破坏模式,平均压缩强度为187.6MPa。复合材料管的弯曲破坏形式为脆性破坏,其平均弯曲强度为262.2MPa,弯曲模量为14.0GPa,与6061铝合金管性能相当,而密度仅为其58%,表现出较好的减重潜力。
Abstract
A bismaleimide composite tube was fabricated by 2D braiding and RTM process.A special clamping tool was also designed refer to GB/T 5350—2005 and SY/T 7318.3—2017 to characterize the axial compression and bending properties of the tube.The mechanical properties of the composite and Al alloy 6061 were compared.The results showed the type of compression failure of the tube was brittle-shear mode with average compression strength of 187.6MPa.The bending failure mode of composite tube was brittle failure,with bending strength and modulus of the tube were 262.2MPa and 14.0GPa,respective,as the same level as the Al alloy.However,the density of the tube was only 58% of the Al alloy,which showed good potential of lightening.
