Title:
CARBON FIBER COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/195383
Kind Code:
A1
Abstract:
The present invention provides a carbon fiber composite material that is obtained by stacking a plurality of carbon fiber sheets, each of which is composed of carbon fiber bundles aligned parallel to each other, and that is characterized in that: a resin layer which contains a porous resin and an epoxy resin is provided between carbon fiber layers that are adjacent to each other in the thickness direction; and the volume resistivity of the resin layer in the thickness direction is 0.05 Ω∙m to 10 Ω∙m. The present invention provides a carbon fiber composite material which is uniformly enhanced in the electrical conductivity in the plate thickness direction, while being capable of exhibiting favorable mechanical characteristics.
