Multi-level-architecture multifiber composite yarn

Abstract

A multi-level-architecture multi-fiber composite yarn includes a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial direction, and a matrix material included with the yarn, wherein the matric material has a second anisotropic expansion coefficient that is different from the first anisotropic expansion coefficient in at least one of the axial or radial directions. A method of fabricating a multi-level-architecture multi-fiber composite yarn includes infiltrating a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial directions with a matrix material having a second anisotropic expansion coefficient different from the first anisotropic expansion coefficient in the axial or radial direction. 一种多层结构的多纤维复合纱线，包括具有沿轴向和/或径向方向的第一各向异性膨胀系数的复合纱线和包含在所述纱线中的基质材料，其中所述基质材料具有第二各向异性膨胀系数，第二各向异性膨胀系数在轴向或径向的至少一个方向上与第一各向异性膨胀系数不同。一种制造多层结构的多纤维复合纱线的方法，所述方法包括将具有第二各向异性膨胀系数的基质材料渗透入在轴向和/或径向方向上具有第一各向异性膨胀系数的复合纱线，所述第二各向异性膨胀系数在轴向或径向方向上不同于第一各向异性膨胀系数。
