Laminar structure having an impregnated fibrous web

A method of improving the dimensional and thermal stability of a fibrous web containing substrate is disclosed. A uniformly or randomly spun or bonded fabric or textile support is impregnated with a curable polymer resin, e.g., an epoxy-polyester resin. The impregnated resin is then fully cured wher...

Zusammenfassung:	A method of improving the dimensional and thermal stability of a fibrous web containing substrate is disclosed. A uniformly or randomly spun or bonded fabric or textile support is impregnated with a curable polymer resin, e.g., an epoxy-polyester resin. The impregnated resin is then fully cured whereupon a polymer resin coat is applied thereto. The coat is maintained in a partial cure state whereby a laminate comprising an internal woven or bonded fabric skeleton impregnated with a fully cured polymer resin and coated with a layer of a partially cured polymer resin is obtained.
