摘要: 热塑性双稳态复合材料由于具有质轻、力学性能优越、空间利用率高等优势,在空间可展开结构领域有着良好的应用前景。为探讨支撑杆件用GF/PP双稳态复合材料的力学性能,本文从玻纤规格、铺设角度、曲率半径出发,对试样进行结构设计,对玻纤织物的拉伸、弯曲、剪切性能,以及平板状态下复合材料的拉伸、弯曲性能进行测试和分析,并着重研究了双稳态复合材料在第一稳态下的轴向压缩性能。研究结果显示:玻纤规格和铺设角度对双稳态复合材料的拉伸、弯曲性能均有一定影响,采用面密度分别为200 g·m-2、300 g·m-2的试样进行±30°铺层时,复合材料轴向和横向的拉伸、弯曲性能较好;而双稳态复合材料压缩性能的影响因素由强到弱包括玻纤规格、铺设角度、曲率半径,面密度为300 g·m-2,铺设角度为[±30°/0°/90°/±30°],曲率半径为2.5 in(1 in≈2.54 cm)的双稳态复合材料的轴向压缩性能较为优越。

Abstract: Thermoplastic bistable composites have promising applications in the field of space deployable structures due to their advantages of light weight, superior mechanical properties and high space utilization. The objective of the paper is to discuss the mechanical properties of GF/PP bistable composite material used for supporting rod. The basic mechanical properties of the glass fiber fabric, the tensile and bending properties of the composite material under the condition of flat plate, and the axial compression property of bistable composites under the first steady state are investigated in this paper by designing the area weight of glass fiber fabric, laying angle and curvature radius. The results show that the area weight of glass fiber fabric and laying angle have a certain effect on the tensile and bending properties of bistable composites. The composites with fabric weighing of 200 g·m-2 or 300 g·m-2 and laying angle of ±30° have better tensile and bending properties in axial and transverse direction. The influence factors of the compression properties of bistable composites include the area weight of glass fiber fabric, laying angle and curvature radius from strong to weak. The axial compression properties of bistable composites are superior when with fabric weighing of 300 g·m-2, laying angle of [±30°/0°/90°/±30°] and curvature radius of 2.5 inch.

Key words: bistable, compression performance, laying angle, radius of curvature, composites
