There is provided a carbon fiber laminate structure having a moderate resilience, compression resilience and compression durability which cannot be afforded by carbon fibers as a raw material, to provide a novel material which comprises carbon fibers as a principal constituent thereof and can be used in application fields closely associated with human sensibilities, for example, as a cushioning material for chairs, beds and the like. The novel material is a three dimensional carbon fiber structure which comprises an aggregate of fibers, not less than 50 wt% of which are carbon fibers and 50 to 100 wt% of which are crimped, and a binder essentially consisting of a thermosetting resin and/or thermally bondable fibers, the fibers being bonded to each other at contacts thereof with the binder to form a three dimensional network, the three dimensional carbon fiber structure having a bulk density of 20 to 80 Kg/m<3> and a compression hardness LC of 0.7 to 0.9 with application of the maximum load of 100 gf/cm<2>. <IMAGE> |
