Claim 8:
9. The cross-ply laminate according to claim 8,
wherein, in the case where the fiber direction of one of the incised prepregs of the cross-ply laminate is 0°, when, in the 25° C. environment, a tensile strain of 2% is applied to the cross-ply laminate in the 0° direction, a total area of opened incisions relative to an area of the cross-ply laminate (the area ratio of the opened incisions) is greater than or equal to 0% and less than or equal to 1%, and
wherein, in the case where the fiber direction of one of the prepregs of the cross-ply laminate is 0°, when, in the 60° C. environment, a tensile strain of 2% is applied to the cross-ply laminate in the 0° direction, the total area of opened incisions relative to the area of the cross-ply laminate (the area ratio of the opened incisions) is greater than or equal to 0% and less than or equal to 1%.
