Abstract:
1. A method of cutting a carbon fiber substrate comprising: cutting a carbon fiber substrate configured from a fabric material comprising at least carbon fibers with a laser such that the substrate is cut at initial conditions which have been set so that a state of said substrate that is being cut with said laser can be suppressed with or prevented from deviating from a target state wherein, 1) when said carbon fiber substrate is cut with said laser at a condition being placed on a receiving jig, said substrate is partially received by said receiving jig, 2) a cutting position of said substrate is set at a position where said substrate is not brought into contact with said receiving jig, 3) a contact supporting portion of said receiving jig relative to said substrate is set in a strip, linear or dot form, and 4) a contact surface to said substrate of the receiving jig is formed from a material having at least a heat insulation property.
