According to one implementation, a composite material molding jigincludes a tubular memberand at least one rigid plate member(A,B) so that a composite material structure O (O, O) having a hollow structure can be formed easily. The tubular memberhas flexibility. The at least one rigid plate member(A,B) reinforces strength of the tubular memberpartially. The tube is used in a state where air is introduced inside the tube. Further, according to one implementation, a composite material molding method includes using the above-mentioned composite material molding jigin order to produce a composite material structure O (O, O) so that the composite material structure O (O, O) having a hollow structure can be formed easily.

Composite material molding jig and composite material molding method

A fiber width adjusting apparatus includes a rotary body. The rotary body is configured to rotate around a rotation axis while interposing a sheet-shaped fiber, and cause, by frictional force generated between the rotary body and the sheet-shaped fiber, force to act on the sheet-shaped fiber while feeding the sheet-shaped fiber in a feed direction to vary a width and an orientation angle of the sheet-shaped fiber. The sheet-shaped fiber is impregnated with a resin or is before the impregnation with the resin. The rotation axis is parallel to a thickness direction of the sheet-shaped fiber. The force contains a component that is in a direction perpendicular to the thickness direction and to the feed direction.

There is provided a joint structure for a fiber reinforced resin and a metal. In the joint structure, respective end portions of a fiber reinforced plastic and a metallic material are joined to each other. A large number of projections having a height that enables the projections to contact fibers constituting the fiber reinforced plastic are formed on a joint surface of the metallic material serving as a part of a joint surface between the fiber reinforced plastic and the metallic material.

Joint structure for fiber reinforced resin and metal

There is provided a joint structure for a fiber reinforced resin and a metal. In the structure, multiple single elements are laminated such that the step-shaped structures are superposed in a thickness direction. Each element is constituted by a metallic material including a step-shaped structure having an end portion that gradually becomes thinner towards an end surface thereof so as to form a step-shaped joint surface, and a fiber reinforced plastic laminated such that an end portion thereof covers the step-shaped structure smoothly. A main welding portion is formed on an outer end of the metallic material by welding mating surfaces of adjacent metallic materials. A secondary welding portion is formed on the plastic side of the main welding portion on all the metallic materials by welding them in the thickness direction.

Joint structure for fiber reinforced resin and metal, and joining method for fiber reinforced resin and metal

There are provided a joint structure for a fiber reinforced resin and a metal, and a joining method for a fiber reinforced resin and a metal. In the joint structure, a plurality of single elements each constituted by a metallic material, which includes a step-shaped structure having an end portion that gradually becomes thinner in a direction of an end surface of the end portion so as to form the step-shaped joint surface, and a fiber reinforced plastic, which is laminated such that end portions thereof cover the step-shaped structure smoothly, are laminated such that the step-shaped structures are superposed in a thickness direction, whereupon the metallic material and the fiber reinforced plastic are adhered to each other and adjacent elements are joined to each other by superposed surfaces thereof. The metallic materials are then welded to each other.
