Method of polymerizing fiber-reinforced resinous materials and product

Claim 1

A METHOD WHICH COMPRISES IMPREGNATING A POROUS FIBROUS BASE WITH A POLYMERIZABLE LIQUID COMPRISING AN OXYGEN-CONVERTIBLE COMPOUND HAVING AT LEAST TWO UNSATURATED, UNCONJUGATED POLYMERIZABLE GROUPS, CAPABLE OF CURING TO A RIGID SOLID RESINOUS STATE, PASSING THE BASE BETWEEN ROLLS WHICH SQUEEZE OUT EXCESS POLYMERIZABLE LIQUID AND ENTRAPPED AIR WHILE APPLYING FLEXIBLE, SUBSTANTIALLY IMPERMEABLE COVERS TO OPPOSITE SIDES OF THE BASE, MINIMIZING INCLUSION OF AIR UNDER THE COVER BY ESTABLISHING AND MAINTAINING A BEAD OF POLYMERIZABLE LIQUID BETWEEN AND IN CONTACT WITH THE COVER AND THE SURFACE OF THE BASE IMMEDIATELY IN FRONT OF THE ROLLS, PARTIALLY POLYMERIZING THE BASE TO FORM AN IMMOBILE, ADHESIVE POLYMER, SLICING A SECTION FROM THE BASE WHILE THE POLYMER REMAINS ADHESIVE AND FURTHER POLYMERIZING THE SECTION UNTIL THE POLYMER IS CURED TO A RIGID SOLID STATE.
