Problems solved by technology

In the technology of collective bending, although each layer with different directions of reinforcing fibers originally requires an appropriate deformation form individually, it deforms in the same way as a whole, so fiber wrinkles or slack are partially generated

Embodiment Construction

[0059] See attached below Figure 1 Preferred embodiments of the present invention will be described.

[0060] Figure 1 to Figure 5 A manufacturing apparatus and a manufacturing method thereof are shown for carrying out a method of manufacturing a tape-shaped reinforcing fiber base material having an arcuate portion according to one embodiment of the present invention. Figure 1 ~ Figure 4 The shown device is used to bend and deform at least a part of the obtained strip-shaped unidirectional reinforcing fiber substrate 2 into an arc shape (direction Y-Y of the curved shape) in the direction along the direction X-X of the substrate length, The strip-shaped unidirectional reinforcing fiber substrate 2 will be as Figure 5 The illustrated reinforcing fiber tows 1 are arranged in parallel in one direction of the base material longitudinal direction X-X. Figure 5 The illustrated base material 2 is configured as a unidirectional reinforcing fiber base material 2 in which reinfo...

Abstract

A process and an apparatus are provided by which a curved reinforcing-fiber strip base constituted of reinforcing fiber strands laid throughout the whole base can be easily obtained without fail. The process and apparatus for producing a reinforcing-fiber strip base having a circular-arc part are characterized by: bringing one side of a strip-shaped, unidirectionally arranged reinforcing-fiber base comprising reinforcing fiber strands arranged parallel in one direction, into contact with a flexible member; deforming at least some of the flexible member into a circular-arc shape in a direction extending along the plane where the member is in contact with the unidirectionally arranged reinforcing-fiber base and thereby deforming the unidirectionally arranged reinforcing-fiber base, which is in contact therewith, into a circular-arc shape; and thereafter separating the flexible member from the unidirectionally arranged reinforcing-fiber base that has been deformed. A multilayer structure, a perform, and a fiber-reinforced resin composite material are provided which each comprises or has been produced using the base.

Description

technical field [0001] The present invention relates to a method and a manufacturing apparatus for a tape-shaped reinforcing fiber base material having an arc-shaped portion bent along the length direction of the base material, a laminate formed using the tape-shaped reinforcing fiber base material, and a molded product using the laminated body. A preform, and a fiber-reinforced resin composite material molded using the preform. Background technique [0002] As is well known, fiber-reinforced resin composites are lightweight materials with high strength and rigidity. When molding long-distance fiber-reinforced resin composite materials, in order to ensure high strength and rigidity in the target direction, a laminate structure is often used, that is, multiple strips that set the orientation direction of the reinforcing fibers in each predetermined direction. A laminate structure obtained by laminating a reinforced fiber base material. Sometimes a laminate in the form of a ...
