Abstract
Abstract Pretreating a first solid surface consisting of a material selected from the group consisting of unfilled poly(arylene sulfide) and fiberglass-filled poly(arylene sulfide) by mechanically roughening this first surface or, in the alternative, pretreating with flame a first solid surface of unfilled poly(arylene sulfide) greatly increases the lap shear strength of an adhesive bond of such a first poly(arylene sulfide) surface to a second solid surface as compared to the same bond without pretreatment of the poly(arylene sulfide) surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
70 words
A laminate structure comprising three layers, the first layer consisting essentially of unfilled poly(arylene sulfide) having a flame-treated surface facing the second layer, the second layer consisting of an adhesive connected to said flame-treated surface, and said third layer consisting of a solid material connected to said second layer of adhesive, said third layer being selected from the group consisting of metals, plastic materials, wood, ceramic materials, glass and concrete.
Claim 2
Dependent Claim
70 words
A laminate structure comprising three layers, the first layer consisting essentially of unfilled poly(arylene sulfide) having a flame-treated surface facing the second layer, the second layer consisting of an adhesive connected to said flame-treated surface, and said third layer consisting of a solid material connected to said second layer of adhesive, said third layer being selected from the group consisting of metals, plastic materials, wood, ceramic materials, glass and concrete.
Claim 3
Dependent Claim
14 words
A laminate in accordance with claim 1 wherein said poly(arylene sulfide) is poly(p-phenylene sulfide).
Claim 4
Dependent Claim
15 words
A laminate in accordance with claim 1 wherein said third layer is a metal layer.
Claim 5
Dependent Claim
87 words
A laminate structure comprising four layers, the first layer consisting of a solid material being covered with the second layer consisting essentially of poly(arylene sulfide) and having a surface facing the third layer, which surface is a flame-treated or mechanically roughened unfilled poly(arylene sulfide) surface and is connected to the third layer consisting essentially of an adhesive material which in turn is connected to the fourth layer consisting of a solid material selected from the group consisting of metals, plastic materials, wood, ceramic materials, glass and concrete.
Claim 6
Dependent Claim
87 words
A laminate structure comprising four layers, the first layer consisting of a solid material being covered with the second layer consisting essentially of poly(arylene sulfide) and having a surface facing the third layer, which surface is a flame-treated or mechanically roughened unfilled poly(arylene sulfide) surface and is connected to the third layer consisting essentially of an adhesive material which in turn is connected to the fourth layer consisting of a solid material selected from the group consisting of metals, plastic materials, wood, ceramic materials, glass and concrete.
Claim 7
Dependent Claim
15 words
A laminate in accordance with claim 4 wherein said first layer is a metal surface.
Claim 8
Dependent Claim
18 words
A laminate in accordance with claim 4 wherein the surface of said fourth layer is a metal surface.
Claim 9
Dependent Claim
19 words
A laminate structure in accordance with claim 6 wherein said first and said fourth layers consist of a metal.
Claim 10
Dependent Claim
14 words
A laminate in accordance with claim 6 wherein said poly(arylene sulfide) is poly(p-phenylene sulfide).
Claim 11
Dependent Claim
74 words
A laminate structure comprising four layers, the first layer consisting of a solid material being convered with the second layer consisting essentially of fiberglass-filled poly(arylene sulfide) having a mechanically roughened surface facing and being connected to the third layer which consists essentially of an adhesive which in turn is connected to the fourth layer consisting of a solid material selected from the group consisting of metals, plastic materials, wood, ceramic materials, glass and concrete.
Claim 12
Dependent Claim
74 words
A laminate structure comprising four layers, the first layer consisting of a solid material being convered with the second layer consisting essentially of fiberglass-filled poly(arylene sulfide) having a mechanically roughened surface facing and being connected to the third layer which consists essentially of an adhesive which in turn is connected to the fourth layer consisting of a solid material selected from the group consisting of metals, plastic materials, wood, ceramic materials, glass and concrete.
