Abstract
PURPOSE: To eliminate the need of mold separating film by a method wherein, a prepreg one side thereof is coated with calcium alginate film to make a separation surface is laminated on one side of the outermost surface of a core layer, holding the separation surface of the prepreg toward outside, to make a unit layered object.
CONSTITUTION: After the substrate 5 is rolled out from a roll 6, it is immersed into the immersion tank 7 containing a thermosetting resin varnish, a water solvent of calcium chloride is coated on one side of the substrate at the section A, followed by the coating of a water solvent of sodium alginate at the section B. Because of said coatings, a reaction occurs on the resin immersed substrate surface, resulting in the formation of calcium alginate film, then, the substrate is sent to the second dryer 10 to obtain a prepreg. Said prepregs are laminated to form a core layer 2, and a unit layered object is obtained by laminating on one side of the outermost surface of the core layer 2 holding the separation surface 14 outwardly. The hardened laminated object is separated at the separation surface 14 after the two separation surfaces 14 are abutted closely each other for heat pressing.
