This mold for prepreg lamination includes a first surface only having a surface flat along one direction; second surfaces having a surface flat along the one direction and disposed at a predetermined angle with respect to the first surface; and a third surface with a cross-sectional shape, which is a surface yielded from a cut in an orthogonal direction to the one direction, that is an arc, and with one end side connected to the first surface and the other end side connected to the second surface. First bend sections having a protruding shape are formed on the second surface and the third surface and serve as boundaries, and one of the surfaces is slanted relative to the other surfaces. On the third surface, the diameter of the arc on the other surface becomes gradually smaller as further away from the first bend section along the one direction.

Mold for prepreg lamination and prepreg lamination method

The present invention includes a first weight scale that senses first information necessary when acquiring the residual amount of a first composite material sheet wound on a first support rod; a second weight scale that senses second information necessary when acquiring the residual amount of a second composite material sheet wound on a second support rod; a first cutting part for cutting the first composite material sheet; a second cutting part for cutting the second composite material sheet; a pressure-bonding mechanism that pressure-bonds the first composite material sheet and the second composite material sheet; and a control device that controls the first cutting part, the second cutting part, and the pressure-bonding mechanism.

Splice device, and composite material automated lamination device

This composite material automatic laminating equipment is provided with a lamination stage a composite material winding unit which supplies a composite material sheet, supply rollers which feed the composite material sheet onto the top surface of the lamination stage or onto another composite material sheet arranged on said top surface, a compaction roller which is arranged downstream of the supply rollers and which makes surface contact with the composite material sheet and presses the composite material sheet, and a cutting section which forms composite material sheet pieces by cutting, in the width direction, the portion of the composite material sheet in surface contact with the compaction roller.

Composite material automatic laminating device

Manufacturing structure using a composite material includes: a tapering step for forming a first tapered surface on a first stiffener in an uncured state; a bending step for bending the stiffener such that a second surface is on the inner side; an arranging step for arranging the first stiffener and a skin at prescribed positions; a vacuum suctioning step for vacuum suctioning the first stiffener and the skin; and a bonding step for curing the first stiffener to bond the first stiffener and the skin. In the tapering step, the angle formed between the first tapered surface and the second surface is an acute angle. In the vacuum suctioning step, the first tapered surface is brought into contact with the skin while maintaining contact between the first surface and the skin, and the first stiffener is deformed so that a second tapered surface is formed on the second surface.
