Abstract
A traction mat wherein the foam is reinforced with a layer of fabric or fiber between the CLCC foam layer and the substrate or underlying surface. The layering is preferably a first foam layer, a first adhesive layer, a fabric and/or fiber layer, followed by a second adhesive layer. This prevents the CLCC foam from being bonded directly to the substrate which allows the fabric/fiber to support the CLCC foam such that the entire assembly can be removed in one piece without the CLCC foam disintegrating. The introduction of the reinforcing fabric and/or fiber layer eliminates any residual CLCC foam from being bonded to the substrate. Consequently, the traction mat can be easily lifted away and removed.
Claims5
A removable fiber-reinforced traction mat comprising a formed composite capable of adhering to a surface, said composite further comprising:
- (a) a layer of cross-linked-closed-cell foam having an upper surface and a lower surface, said layer of cross-linked-closed-cell foam having a thickness between about 2 and 15 millimeters and constituting between about 30% and 90% by weight of said composite;
- (b) a first adhesive layer comprising a first adhesive bonded to said lower surface, said first adhesive layer having a thickness between about 0.05 and 0.5 millimeters;
- (c) a layer of a synthetic woven textile fiber having a tensile strength of at least 2.8 lbs maximum force at break (direction 1) and 2.5 lbs maximum force at break (direction 2) and a tongue tear strength of at least 1.0 lb-f (tear in warp direction) and 1.0 lb-f (tear in filling direction) and further having an upper fabric face and lower fabric face, said layer of synthetic woven textile fiber having a thickness between 0.1 and 1.0 millimeters and said upper fabric face of said layer of synthetic woven textile fiber bonded to said first adhesive layer;
- and
- (d) a second adhesive layer comprising a second adhesive bonded to said lower fabric face, said second adhesive layer having a thickness between about 0.1 and 1.0 millimeters, thereby forming a composite and attached to a substrate.
