Abstract

PURPOSE: To obtain reinforced resin molded goods which are excellent in mechanical strength and dimensional stability, free from camber and deformation and suitable for providing a trimmed material by a method wherein additional materials for improving strength, special resin materials are arranged subsequently in the space between molds and then they are press-molded.
CONSTITUTION: Preferably, in the mold space between molds having steps 4 or grooves 5 which can place or fix an additional material for improving strength on the circumferential parts of the inner bottom or the inner sides of one mold, an additional material 6 (e.g. iron, ceramics, etc.) for improving strength is arranged, then the thermoplastic material (e.g. polyethylene etc.) mixed with long glass fibers (preferable lengths: 10W100mm) heated at molding temperatures is arranged and these molds are closed for press-molding. Additonally, the preferable molding conditions are found at temperatures 150W380°C and pressures 100W300kg/cm2.
