METHOD AND MOLD FOR MANUFACTURING FIBER-REINFORCED PLASTIC STRUCTURE

摘要

In the manufacturing method of the present invention, as preparation for providing a mold 30 with protrusions 31 and 32 to be printed on an FRP material of a skin 1 in co-bold molding, which requires resetting of the skin 1 to the mold 30, a long protrusion 32A and a short protrusion 32B are interchangeable as one protrusion 32. The long protrusion 32A is printed to form a second recessed part 12 in the skin 1, and before the skin 1 is reset, the long protrusion 32A is replaced with the short protrusion 32B. In this way, as the short protrusion 32B is housed in the second recessed part 12 formed during elongation of the mold 30, the skin 1 can be reset in the state of being positioned relative to the mold 30 by the first protrusion 31 and the short protrusion 32B.

1. A method for manufacturing a fiber-reinforced plastic structure, comprising:
as preparation for positioning a first fiber-reinforced plastic member relative to a mold at places apart from one another in a predetermined direction, providing the mold with a first printing part at a reference one of the places, and detachably providing the mold with a second printing part, for which a near printing part and a far printing part at different distances from the first printing part in the predetermined direction are interchangeably arranged; a molding step of molding the first fiber-reinforced plastic member by using the mold; a resetting step of returning the first fiber-reinforced plastic member, which has been removed from the mold, to the mold; and an integrating step of integrating a second fiber-reinforced plastic member into the first fiber-reinforced plastic member, wherein the molding step includes:
a step of providing the mold with the near printing part, which is closer to the first printing part, as the second printing part; anda heating and printing step of heating the material of the first fiber-reinforced plastic member, and printing the first printing part on the material to form a first printed part while printing the near printing part on the material to form a second printed part, the resetting step includes:
a far printing part installing step of providing the mold with the far printing part; anda positioning and resetting step of setting the fiber-reinforced plastic member in a state of being positioned relative to the mold, by using the first printing part, which is housed in the first printed part, and the far printing part, which is located in a region of the near printing part after its elongation during the heating and printing step with reference to the first printing part and which is therefore housed in the second printed part, anda fiber-reinforced plastic structure integrated with the first fiber-reinforced plastic member and the second fiber-reinforced plastic member is obtained by the integrating step.
