PROBLEM TO BE SOLVED: To manufacture a synthetic resin composite plate of uniform performance for manufacturing synthetic resin composite plates of not only rectangular shape, but also of round and other optional shapes, in which foams can be formed into the uniform size in the case sections of not sufficient thickness are formed, and cracks are not generated on a core material. SOLUTION: In a method for manufacturing a synthetic resin composite plate formed of a core material 15 of a thermosetting resin foamed body and fiber reinforced plastic outer face layers 13 and 14 coating the upper and lower, front and rear and left and right of the core material, upper box-shaped sections 13 constituting the upper halves of the outer face layers and lower box-shaped sections 14 constituting the lower halves are formed of the above fiber reinforced plastic separately, and a mixture (foamed resin) 15 of thermosetting resin with compressed gas is filled respectively in the upper and lower box- shaped sections 13 and 14, and then the upper and lower box-shaped sections 13 and 14 are overlapped in the matching mold shape and foamed resin 15 is cured to manufacture the core material. |
