Problems solved by technology

[0005] The existing technology is such as [International Publication No. 2013 / 081058 pamphlet]. However, in the prior art, because the prepreg is different from the metal material, the cured prepreg is easily attached to the mold during stamping. When the cured prepreg is separated from the mold (demoulding), the mold needs to be cooled first, and the time spent for each cooling will cause a corresponding decrease in production efficiency
The existing mold cooling method is to use time-consuming water cooling or oil cooling, and when it is necessary to continue to make fiber-reinforced composite molded products after cooling, the cooled mold must be heated to the original temperature, so in the continuous production of fiber The entire process of reinforcing composite moldings takes too long

Embodiment Construction

[0023] This embodiment relates to a manufacturing method of a fiber-reinforced composite material molding product. The prepreg obtained by impregnating and drying fiber bundles such as carbon fiber and glass fiber with thermoplastic resin or thermosetting resin is punched and formed to obtain fiber reinforcement. Resin composite material molding products, or fiber-reinforced resin composite material / metal integral molding products formed by bonding the above-mentioned prepregs with metals such as aluminum, iron, and titanium after pressure and heating. Fiber-reinforced composite molded products can be used in parts such as aircraft and automobiles depending on the application and shape.

[0024] The manufacturing method of the present embodiment adopts such as figure 1 The stamping forming device 1 of the shown upper mold 3 and lower mold 4 is realized, the upper mold 3 of the device is movable up and down, and the compression (stamping) object is realized between the upper mo...

Abstract

A method for manufacturing a fiber reinforced composite material molded product using a stamping die in the stamping field comprises: arranging a prepreg between an upper die and a lower die for pressing and heating at the same time; separating the upper die and the lower die; and applying cooled gas to cured prepregs located on stamping surfaces of the upper and lower dies and the stamping surfaces to demould the cured prepregs from the die. Compared with a method in the prior art, the method is better in productbility and less in energy loss.

Description

[0001] The application date of this invention request: January 8, 2016, the application number: Japanese Patent Application No. 2016-2827, the title of the invention: the manufacturing method of the fiber-reinforced composite material molded product and its stamping die, and the priority of the Japanese prior application. technical field [0002] The present invention relates to a technology in the field of stamping molding, in particular to a method for manufacturing a fiber-reinforced composite material molded product after stamping and molding a prepreg, and a stamping mold used in the manufacturing method. Background technique [0003] Fiber-reinforced composite molding products generally use materials such as epoxy resin, so they can be manufactured by impregnating fiber bundles with epoxy resin, drying them to obtain prepregs, and then heating and pressurizing them to cure them. [0004] It is recorded in paragraph [0022] of [International Publication No. 2013 / 081058 pa...
