Abstract
An object of the present invention is to provide a laminated molding having high strength and reduced possibility of layer separation, a multiaxially reinforced laminated molding capable of reducing the production time and the production cost, and a method for producing the same. A multiaxially reinforced laminated molding (F) is formed of fiber-reinforced layers (SR1 to SR3), each including reinforcing fiber sheets stacked on top of each other such that reinforcing fibers of the reinforcing fiber sheets are oriented in three axial directions. Resin layers (TP1 and TP2) are disposed among the fiber-reinforced layers. The resin layers (TP1 and TP2) are formed of many particles of a thermoplastic resin material that are substantially uniformly distributed and heat-sealed together. The distributed thermoplastic resin material is adhered to the adjacent fiber-reinforced layer through heat-sealing. The thermoplastic resin material has many fine gaps and the entirety of the fiber-reinforced layers and the resin layers are thoroughly impregnated with the thermosetting resin material.
