To obtain the tensile mechanics of the arrow combination structure with carbon fiber–epoxy resin composite, the quasi-static experiments were carried out in this paper. Firstly, the concave hexagon single-cell structure and star single-cell structure were designed, and the tensile force–displacement characteristics of the two structures were obtained by cyclic loading and single loading experiments. The mechanism of the “step effect” on the force–displacement curve was analyzed, and the failure mode of the two structure was emphatically investigated. Then, the stress–strain relationship of the structures was drawn, and the constitutive model of representative elements was established. The energy absorption and specific energy absorption of the two structures were calculated, too. The results show that the concave hexagonal single-cell structure has a higher stiffness (about 2.2 times of the star single-cell structure), but the star single-cell structure has a better plastic deformation range (about 2.2 times of the concave hexagonal single-cell). On the whole, the concave hexagonal single-cell structure has the linear elastic characteristics, but the star single-cell structure has the elastic–plastic characteristics and the strengthening stage is obvious. The specific energy absorption of concave hexagonal single-cell structure is 5/8 of the star single-cell structure.

为了获得碳纤维-环氧树脂复合材料的箭头组合结构的拉伸力学，本文进行了准静态试验。首先，设计了凹六边形单孔结构和星形单孔结构，并通过循环载荷和单载荷实验获得了两种结构的拉力-位移特性。分析了力-位移曲线上“阶跃效应”的机理，并着重研究了两种结构的破坏模式。然后，绘制了结构的应力-应变关系，并建立了代表单元的本构模型。还计算了两个结构的能量吸收和比能量吸收。结果表明，凹形六边形单孔结构具有较高的刚度（约为星形单孔结构的2.2倍），而星形单孔结构具有较好的塑性变形范围（约为凹形六边形单孔结构的2.2倍）。 -细胞）。总体而言，凹面六角形单孔结构具有线性弹性特征，而星形单孔结构具有弹塑性特征，并且强化阶段明显。凹形六边形单电池结构的比能量吸收为星形单电池结构的5/8。凹面六角形单胞结构具有线性弹性特征，而星形单胞结构具有弹塑性特征，强化阶段明显。凹形六边形单电池结构的比能量吸收为星形单电池结构的5/8。凹面六角形单胞结构具有线性弹性特征，而星形单胞结构具有弹塑性特征，强化阶段明显。凹形六边形单电池结构的比能量吸收为星形单电池结构的5/8。
