Abstract: A fiber reinforced resin base material is formed by impregnating a continuous reinforcing fiber(s) or a reinforcing fiber material having a discontinuous fiber(s) dispersed therein with a resin composition which exhibits a single glass-transition temperature before and after being heated at 400° C. for one hour, wherein the resin composition is composed of (A) a thermoplastic resin having a glass-transition temperature of 100° C. or more and (B) a thermoplastic resin having a glass-transition temperature of less than 100° C.
The fiber reinforced resin base material has excellent impregnation properties and thermal stability, having fewer voids, and having surface quality and high heat resistance.

Abstract: A stampable sheet includes a resin and carbon fiber sheet including fiber bundles of discontinuous carbon fibers, wherein the carbon fiber sheet includes fiber bundles having a bundle width of 50 μm or greater and opened fibers ranging from fiber bundles having a bundle width less than 50 μm to fibers obtained by opening to the single-fiber level. When the direction along which the opened fibers have been oriented most is a 0° direction and the range of from the 0° to 90° direction is divided into angular zones, the distribution curve showing the proportion of the number of fiber bundles in each angular zone to that in all angular zones and the distribution curve showing the proportion of the number of opened fibers in each angular zone to that in all angular zones are reverse to each other in terms of gradient of the 0° to 90° direction.
