PURPOSE:To enhance the adhesion of a core material with a fiber reinforced synthetic resin layer by a method wherein a thermosetting resin cured at relatively low temp. is supplied to the surface of the core material while the core- material is transferred in one direction and a reinforcing fiber impregnated with a thermosetting resin cured at relatively high temp. is supplied to the outer periphery thereof to perform pultrusion. CONSTITUTION:At first, a core material 1 is continuously transferred in a molding direction to be guided into a liquid tank 2 and the surface of the core material 1 is coated with an unsaturated polyester resin solution 3 cured at a relatively low temp. Glass rovings 5, 5 are delivered to be guided into a liquid tank 7 to be impregnated with an unsaturated polyester resin solution 6 cured at a relatively high temp. and guided to the outer periphery surface of the core material 1 by an arranging apparatus 8 and continuous mats 9, 9 are delivered to be superposed on the glass rovings 5, 5 while arranged in the same way by the arranging apparatus 8. |
