ABSTRACT:
A method of molding fiber-reinforced thermoset resin articles having improved mechanical properties. A thermosettable organic material is injected into a mold containing a fiber web. The molding composition includes (a) a thermosettable organic material containing two or more polymerizable carbon-carbon double bonds, (b) an ethylenically unsaturated monomer which forms a liquid homogeneous mixture with and is copolymerizable with (a) and is different from (a), and (c) an effective amount of an initiator or a mixture of initiators characterized by a ten-hour half life temperature, or in the case of a mixture of initiators, and average ten-hour half life temperature, of greater than about 50.degree. C. and less than 105.degree. C., which produces on decomposition less than 1.0 milliliter of gas per gram of resin as measured at a temperature of 25.degree. C. and a pressure of one atmosphere.
