Abstract
Abstract The invention relates to a method of fabricating a fiberglass-resin impregnated composite article which has a non porous surface formed by melting and curing a suitable polymeric film thereon. The process further involves coating an adhesive layer having a release sheet thereon over the non-porous melted polymer surface for bonding onto a substrate, and the invention further relates to the particular formed article and a process of forming an air-conditioning frame.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
A method of making an air conditioning frame having an insulating article thereon, comprising coating a resin impregnated, partially cured fiberglass batt on a first surface with a layer of compatible resin; applying a porous non-woven polymeric sheet onto the coated resin layer to form an article; forming and curing the article at elevated temperature and pressure wherein the polymeric sheet melts and forms a non-porous coating on the first surface of the cured article; coating a layer of effective adhesive on the first surface having the non-porous coating; bonding the article in a desired location to an air conditioning frame.
Claim 2
Independent Claim
101 words
A method of making an air conditioning frame having an insulating article thereon, comprising coating a resin impregnated, partially cured fiberglass batt on a first surface with a layer of compatible resin; applying a porous non-woven polymeric sheet onto the coated resin layer to form an article; forming and curing the article at elevated temperature and pressure wherein the polymeric sheet melts and forms a non-porous coating on the first surface of the cured article; coating a layer of effective adhesive on the first surface having the non-porous coating; bonding the article in a desired location to an air conditioning frame.
Claim 3
Dependent Claim
16 words
A method in accordance with claim 1 wherein the adhesive is a high solids content adhesive.
Claim 4
Dependent Claim
32 words
