Abstract: 1. A METHOD OF MANUFACTURING FIBROUS COMPOSITIONS IMPREGNATED WITH SYNTHETIC RESINS COMPRISING THE STEPS OF: (A) IMPREGNATING FROM 10-70 PARTS BY WEIGHT OF REINFORCING FIBERS WITH FROM 90-30 PARTS BY WEIGHT OF A POLYMERIZABLE COMPOSITION WHICH HAS BEEN PREPARED BY (B) MIXING IN PARTS BY WEIGHT 100 PARTS OF A POLYMERIZABLE UNSATURATED POLYESTER OF A CARBOXYLIC ACID, 0.5 TO 2 PARTS OF AN INITIATOR FOR THE POLYMERIZATION OF SAID POLYESTER, 0.5 TO 4 PARTS OF ONE OR MORE ALKALINE EARTH METAL OXIDES, 1 TO 10 PARTS OF A MINERAL OR A COMPOUND COMPRISING IN ITS CHEMICAL STRUCTURE WATER OF CRYSTALLIZATION AND ADAPTED TO RELEASE THE WATER OF CRYSTALLIZATION IN THE COMPOSITION WHEN THE COMPOSITION IS HEATED; AND (C) HEATING THE RESULTING IMPREGNATED PRODUCT AT A TEMPERATURE OF 50* TO 100*C. FOR A PERIOD OF 2-20 MINUTES.
