桁架结构在航空航天和建筑工业领域有着广泛的应用。复合材料桁架结构在充分发挥复合材料低密度、高比强度、高比模量、耐腐蚀和抗疲劳等优异性能的基础上,不仅可以减轻构件质量,还能够增加有效载荷,因此在研究与应用方面日益得到重视。介绍了组成复合材料桁架的杆件、接头的典型成型工艺方法,比较了复合材料桁架结构中常见连接方式的优缺点。
Truss system has been widely applied in aerospace and construction industries.Based on the excellent performance of low density,high specific strength,high specific modulus,corrosion resistance and fatigue resistance of the composite material,composite truss not only can reduce the component quality,but also increase the payload.Composite truss structures have attracted more and more attention on research and application.Several typical methods for manufacturing composite truss and joint were introduced.Besides,the advantages and disadvantages of the connection methods in composite truss structures were compared.
