    • An axially stretchable fiber-reinforced composite material, comprising an elastically deformable matrix having a low modulus of elasticity, and a fabric core encapsulated by the matrix. The core comprises first fibers interlaced with second fibers, with the first fibers being in a non-parallel orientation relative to the material's longitudinal axis, and the second fibers are non-parallel relative to the first fibers when the composite material is in a retracted position. The composite material is stretchable between the retracted and extended positions. The fibers have a high modulus of elasticity. The composite material has a non-linear modulus relative to elongation of the composite material between the retraced and extended positions. Movement of the material toward the extended position causes the first and second fibers to rotate relative to each other and in a direction toward alignment with the longitudinal axis, and the matrix material biases the composite material toward the retracted position.
    • 一种轴向可拉伸的纤维增强复合材料,包括具有低弹性模量的可弹性变形的基体和由基体包封的织物芯。 芯包括与第二纤维交织的第一纤维,其中第一纤维相对于材料的纵向轴线处于非平行取向,并且当复合材料处于缩回位置时,第二纤维相对于第一纤维不平行 。 复合材料在缩回位置和延伸位置之间是可拉伸的。 纤维具有高弹性模量。 复合材料具有相对于回卷和延伸位置之间的复合材料的伸长率的非线性模量。 材料朝向延伸位置的运动使得第一和第二纤维相对于彼此旋转并且沿着与纵向轴线对准的方向旋转,并且基体材料朝向缩回位置偏压复合材料。
