Abstract
A system for providing improved engineered-composite materials, equipment, and manufacturing processes.
Claims25
A waterproof, non-breathable flexible laminate comprising:
- (a) a first unidirectional tape layer comprising monofilaments coated in an adhesive, all of said monofilaments lying in a first predetermined direction;
- (b) a second unidirectional tape layer comprising monofilaments coated in an adhesive, all of said monofilaments lying in a second predetermined direction, said second unidirectional tape layer bonded to said first unidirectional tape layer;
- (c) a third unidirectional tape layer comprising monofilaments coated in an adhesive, all of said monofilaments lying in a third predetermined direction, said third unidirectional tape layer bonded to said second unidirectional tape layer;
- (d) a stretchable non-breathable urethane membrane film bonded to said first unidirectional tape layer opposite said second unidirectional tape layer;
- and
- (e) a stretchable tricot knit layer bonded to said third unidirectional tape layer opposite said second unidirectional tape layer,
- wherein said monofilaments have diameters less than 20 microns;
- and wherein individual monofilaments abut adjacent monofilaments or wherein spacing between individual monofilaments within an adjoining strengthening group of monofilaments is within a gap distance in the range between non-abutting monofilaments up to nine times the monofilament major diameter.
