Abstract
Official abstract text for this publication.
A fiber-reinforced composite material has a fabric base material including laminated obliquely-crossed fabric layers, each of which is configured by weaving first and second reinforced fiber bundles, which obliquely cross each other. In adjacent two of the fabric layers, one of an orientation of the first reinforced fiber bundles and an orientation of the second reinforced fiber bundles in one fabric layer is the same as one of an orientation of the first reinforced fiber bundles and an orientation of the second reinforced fiber bundles of the other fabric layer. A single-orientation layer is placed between the adjacent fabric layers such that an orientation of fiber bundles of the single-orientation layer is the same as an orientation of reinforced fiber bundles having the same orientation as each other in the adjacent fabric layers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fiber-reinforced composite material comprising a fabric base material including laminated obliquely-crossed fabric layers, wherein each of the obliquely-crossed fabric layers is configured by weaving a plurality of first reinforced fiber bundles and a plurality of second reinforced fiber bundles, wherein the first reinforced fiber bundles are arranged in parallel to each other, and the second reinforced fiber bundles obliquely cross the first reinforced fiber bundles and are arranged in parallel to each other, the obliquely-crossed fabric layers are laminated such that, in adjacent two of the obliquely-crossed fabric layers in a lamination direction of the obliquely-crossed fabric layers, one of an orientation of the first reinforced fiber bundles and an orientation of the second reinforced fiber bundles in one obliquely-crossed fabric layer is the same as one of an orientation of the first reinforced fiber bundles and an orientation of the second reinforced fiber bundles of the other obliquely-crossed fabric layer, a single-orientation layer, which includes a plurality of fiber bundles arranged in parallel to each other, is placed between the adjacent obliquely-crossed fabric layers in the lamination direction of the obliquely-crossed fabric layers, and the single-orientation layer is placed between the adjacent obliquely-crossed fabric layers such that an orientation of the fiber bundles of the single-orientation layer is the same as an orientation of reinforced fiber bundles having the same orientation as each other in the adjacent obliquely-crossed fabric layers. 2. The fiber-reinforced composite material according to claim 1 , wherein, in each of the obliquely-crossed fabric layers, the orientation of the second reinforced fiber bundles is at 45 degrees relative to the orientation of the first reinforced fiber bundles. 3. The fiber-reinforced composite material according to claim 1 , wherein the single-orientation layer is one of two single-orientation layers placed between the adjacent obliquely-crossed fabric layers.
