Description
上記課題を解決する繊維束は、複数の強化繊維を有するとともに繊維基材を構成し、熱硬化性樹脂であるマトリックス樹脂を前記繊維基材に対して含浸させることにより繊維強化複合材を製造するために用いられる繊維束であって、熱可塑性樹脂からなる靭性強化剤を有し、前記靭性強化剤の少なくとも一部が内部に配置されている。 A fiber bundle that solves the above problems has a plurality of reinforcing fibers and constitutes a fiber base material, and a fiber reinforced composite material is manufactured by impregnating the fiber base material with a matrix resin that is a thermosetting resin. A fiber bundle used for the purpose of manufacturing, having a toughness enhancer comprising a thermoplastic resin, at least a portion of the toughness enhancer being disposed therein.
ここで、繊維束の内部とは、複数の強化繊維のうち、繊維束の最外周に配置される複数の強化繊維により形成される繊維束の表面よりも繊維束の内側の部分である。これによれば、熱可塑性樹脂からなる靭性強化剤の少なくとも一部が繊維束の内部に配置されているため、熱硬化性樹脂であるマトリックス樹脂を繊維基材に対して含浸させる際に、靭性強化剤がマトリックス樹脂によって流れてしまうことを抑制することができる。その結果、繊維強化複合材の靭性を強化することができる。 Here, the inside of the fiber bundle is a portion inside the fiber bundle from the surface of the fiber bundle formed by the plurality of reinforcing fibers arranged at the outermost periphery of the fiber bundle among the plurality of reinforcing fibers. According to this, since at least part of the toughness reinforcing agent made of thermoplastic resin is arranged inside the fiber bundle, when impregnating the fiber base material with the matrix resin, which is a thermosetting resin, It is possible to suppress the flow of the toughness enhancer due to the matrix resin. As a result, the toughness of the fiber-reinforced composite material can be enhanced.
上記課題を解決する繊維基材は、請求項１又は請求項２に記載の繊維束を有する。
これによれば、繊維基材は、熱可塑性樹脂からなる靭性強化剤の少なくとも一部が内部に配置されている繊維束を有するため、繊維強化複合材を製造するために、熱硬化性樹脂であるマトリックス樹脂を繊維基材に対して含浸させる際に、靭性強化剤がマトリックス樹脂によって流れてしまうことを抑制することができる。その結果、繊維強化複合材の靭性を強化することができる。
A fiber base material for solving the above problems has the fiber bundle according to claim 1 or claim 2.
According to this, since the fiber base material has a fiber bundle in which at least a part of the toughness reinforcing agent made of a thermoplastic resin is arranged, a thermosetting resin can be used to produce a fiber-reinforced composite material. When impregnating a fiber base material with a certain matrix resin, it is possible to prevent the toughness enhancer from flowing out due to the matrix resin. As a result, the toughness of the fiber-reinforced composite material can be enhanced.
上記課題を解決する繊維強化複合材は、請求項３に記載の繊維基材に対して熱硬化性樹脂であるマトリックス樹脂を含浸させることにより製造される。
これによれば、繊維強化複合材は、熱可塑性樹脂からなる靭性強化剤の少なくとも一部が内部に配置されている繊維束により構成されている繊維基材に対して熱硬化性樹脂であるマトリックス樹脂を含浸させることにより製造されている。したがって、繊維強化複合材を製造するために、熱硬化性樹脂であるマトリックス樹脂を繊維基材に対して含浸させる際に、靭性強化剤がマトリックス樹脂によって流れてしまうことを抑制することができる。その結果、繊維強化複合材の靭性を強化することができる。
A fiber-reinforced composite material that solves the above problems is produced by impregnating the fiber base material according to claim 3 with a matrix resin that is a thermosetting resin.
According to this, the fiber-reinforced composite material is a matrix made of a thermosetting resin with respect to a fiber base material composed of fiber bundles in which at least part of a toughness reinforcing agent made of a thermoplastic resin is arranged. It is manufactured by impregnating with resin. Therefore, when impregnating a fiber base material with a matrix resin, which is a thermosetting resin, in order to produce a fiber-reinforced composite material, it is possible to prevent the toughness enhancer from flowing out due to the matrix resin. . As a result, the toughness of the fiber-reinforced composite material can be enhanced.
