Abstract
A carbon fiber composite material compact contains less of expensive carbon fibers, and the compact can therefore be used for general purposes which do not require highly superior physical properties. The carbon fiber composite material compact is produced by staking a first carbon fiber layer, a core layer, a second carbon fiber layer so as to form a laminate, and then compacting the laminate while impregnating an impregnable resin therein.
Claims3
A compact carbon fiber composite material comprising:
- a first carbon fiber layer;
- a core layer;
- a second carbon fiber layer;
- and
- an impregnable resin,
- wherein the first carbon fiber layer, the core layer, and the second carbon fiber layer are stacked to form a laminate,
- the laminate is compacted while impregnating the impregnable resin therein;
- and
- wherein the core layer is made of at least one of a nonwoven fabric, cut fibers, soft foam, and paper.
