Abstract
PURPOSE: To make it possible to prepare the titled laminate under a low pressure condition by the heat and pressure molding by using a sheet made of a specific semi- solid unsaturated polyester containing calcium oxide.
CONSTITUTION: 100pts.wt. of an unsaturated polyester (wherein an acid value is pref. about 50 or less) obtained by reacting a saturated polybasic acid (e.g.: phthalic anhydride), an unsaturated polybasic acid (e.g.: fumaric acid) and a glycol (e.g.: propylene glycol), about 50W150pts.wt. of a vinyl monomer (wherein styrene is pref.), about 0.5W2pts.wt. of a polymerization initiator and about 0.5W 2pts.wt of a thickening agent containing calcium oxide are compounded to prepare an unsaturated polyester composition. Subsequently, about described unsaturated polyester resin composition containing a reinforcing fiber such as a glass fiber compounded therein is interposed between releasing papers and, after the obtained laminated structure is pressed, cured at about 20W60°C until the viscosity (at 25°C) of said unsaturated polyester is reached to about 20W150 thousands poise.
