A production method for a fiber reinforced composite material includes heating a preform formed by laminating a prepreg layer (I) including a reinforcement fiber (A) and a thermosetting resin (B-1) with a resin layer (II) including a thermosetting resin (B-2) and a solid additive (C) to cure the thermosetting resin (B-1) and the thermosetting resin (B-2), the cured resin layer (II') formed by curing the resin layer (II) having an average thickness of 35 &#x3bc;m or more and 300 &#x3bc;m or less.

Method of producing fiber-reinforced composite material, resin base material and preform

Provided are the following: a sandwich structure formed from a core component comprising a discontinuous reinforcing fiber, a thermoplastic resin and voids, and a skin component comprising a continuous reinforcing fiber and a matrix resin, wherein in the core component, 30% or more of the discontinuous reinforcing fiber is covered with the thermoplastic resin and monofilaments of the discontinuous reinforcing fiber intersect one another via the thermoplastic resin; an integrally formed article using the sandwich structure; and methods for the production therefor.

Sandwich structure and integrally formed article using the same, and methods for production thereof
