Method for manufacturing a chassis member
A chassis member capable of improving manufacturing efficiency is disclosed. The chassis member includes a laminate in which an interlayer is provided between a pair of fiber-reinforced resin plates made of reinforced fiber impregnated with thermoplastic resin. A frame body formed of thermoplastic resin is joined to an edge of the laminate. The edge of the laminate is provided with a thin plate portion thinner than the other portion. The frame body is joined to the thin plate portion.
1. A method comprising:
providing an interlayer between a pair of fiber-reinforced resin plates made of reinforced fiber impregnated with thermoplastic resin for manufacturing a laminate;
after said laminate has been disposed inside a mold, injecting thermoplastic resin into a cavity space of said mold;
pressing and heating an edge of said laminate by said injected thermoplastic resin to form a thin plate portion thinner than another portion on said edge of said laminate; and
joining a frame body formed of said injected thermoplastic resin to said thin plate portion.
2. The method of claim 1 , further comprising forming a bent portion on said edge when said edge of said laminate is pressed and heated.
3. A method comprising:
providing an interlayer between a pair of fiber-reinforced resin plates made of reinforced fiber impregnated with thermoplastic resin for manufacturing a laminate;
after said laminate has been disposed inside a first mold, pressing and heating an edge of said laminate to form a thin plate portion thinner than another portion; and
after said laminate formed with said thin plate portion is disposed inside a second mold, injecting thermoplastic resin into a cavity space of said second mold; and
joining a frame body formed of said injected thermoplastic resin to said thin plate portion.
4. The method of claim 3 , wherein said pressing and heating further includes pressing and heating an edge of said laminate to form a thin plate portion, including a thin interlayer portion formed from said interlayer portion, thinner than another portion.
5. The method of claim 1 , wherein said pressing and heating further includes pressing and heating an edge of said laminate to form a thin plate portion, including a thin interlayer portion formed from said interlayer portion, thinner than another portion.
