A set of regions Si are arranged in a movable region M which is set so that the fibers of a fiber bundle can move in the width direction. Each region Si comprises a fiber-spreading region Ai and an expansion region Bi. Each fiber-spreading region Ai moves the fibers in the width direction while bending said fibers by letting a fluid pass through the fiber bundle, thereby spreading the fiber bundle to a width Wi (i = 1, …, n).

A reinforced thermoplastic-resin multilayer sheet material which includes, as a matrix, a thermoplastic resin excellent in suitability for recycling and impact resistance and which has high quality and is excellent in mechanical properties and draping properties. Also provided are: a process for efficiently producing the reinforced thermoplastic-resin multilayer sheet material in a short time; and a reinforced thermoplastic-resin multilayer molding obtained by forming the reinforced thermoplastic-resin multilayer sheet material and retaining the high quality and mechanical properties. The reinforced thermoplastic-resin multilayer sheet material (11) comprises reinforcing thermoplastic-resin sheet materials (21A) to (21D) superposed together which each is composed of a reinforcing fibrous sheet material (31) obtained by paralleling reinforcing fibers (31f) in a given direction and forming them into a sheet and a thermoplastic-resin sheet material (41) adherent to one side of the reinforcing fibrous sheet material (31), the sheet materials (21A) to (21D) having been united together by stitching with a thermoplastic-resin fiber bundle (51) for uniting which is made of the same material as the thermoplastic-resin sheet materials (41). The reinforcing fibrous sheet materials (31) have been superposed so that their reinforcing directions are multi-axial.

The invention provides a multiaxially reinforced laminated molding which has high strength and little suffers from delamination and which brings about shortening in the production time and reduction in the production cost; and a process for the production of the same. The multiaxially reinforced laminated molding (F) comprises fibrous reinforcement layers (SR1 to SR3) which contain reinforcing fiber sheets and are laminated in such a way that the reinforcing fibers of the reinforcing fiber sheets are arranged in three axial directions. Resin layers (TP1 and TP2) are formed among the fibrous reinforcement layers. The resin layers (TP1 and TP2) are each constituted of many granules of a thermoplastic resin material which are distributed nearly uniformly and heat-fused with each other and which also adhere to adjacent fibrous reinforcement layers through the heat fusion of the material. The thermoplastic resin material contains many fine voids, whereby the fibrous reinforcement layers and the resin layers are wholly uniformly impregnated with a thermosetting resin material.
B29C 43/12 - Isostatic pressing, i.e. using non-rigid pressure-exerting members against rigid parts or dies using bags surrounding the moulding material
B29B 11/16 - Making preforms characterised by structure or composition comprising fillers or reinforcements
Fiber composite materials using thin plies with a thickness of less than 0.08 mm provide improved delamination resistance and thinner minimum gauge for laminates. Thin plies may be hybridized with conventional plies, interlaced for strength, and used with adhesives as reinforcement in bonding.
