Abstract A method of protecting the surface of a moulded plastic part made from synthetic resin, fillers and/or fibers by application of a protective film of ceramic, metallic, or metallic-ceramic composition which is sprayed onto the surface of the parent material wherein the adhesion between the parent material and the sprayed-on protective film is improved by application of an intermediate stratum, in the form of a fabric or other mesh-like material made from an organic or inorganic substance, to the surface of the parent material prior to the spraying step. The mesh-like material is resistant to temperatures higher than the curing temperature of the synthetic resin and may be applied either simultaneously with production of the moulded plastic part and afterwards by means of adhesives.
The method as defined in claim 1 wherein the application of said intermediate layer of bonding and heat-absorbing material to the surface portion of the fibre-reinforced synthetic resin component is carried out concurrently with the moulding thereof.
Claim 2
Dependent Claim
71 words
The method as defined in claim 1 wherein the application of said intermediate mesh layer of bonding and heat-absorbing material to the surface portion of the fibre-reinforced synthetic resin component is carried out concurrently with the moulding thereof and which includes the further step of impregnating said intermediate mesh layer with a synthetic resin forming a chemical bond with the fibre-reinforced synthetic resin component when the latter is moulded and cured.
Claim 3
Dependent Claim
26 words
The method as defined in claim 3 and which includes the further step of roughening the intermediate mesh layer prior to impregnation with the synthetic resin.
Claim 4
Dependent Claim
24 words
The method as defined in claim 1 wherein said intermediate layer of a bonding and heat-absorbing material is constituted by a metallic wire mesh.
Claim 5
Dependent Claim
38 words
The method as defined in claim 1 wherein said intermediate layer of a bonding and heat-absorbing material is constituted by a mesh made from fibres selected from the group consisting of polyester, carbon, boron, asbestos, porecelain and glass.
Claim 6
Dependent Claim
44 words
The method as defined in claim 1 wherein the step of applying said layer of a bonding and heat-absorbing material to the surface portion of the moulded synthetic resin component is effected by application of an adhesive therebetween after said component has been moulded.
