摘要:
A waterproof breathable material has a higher strength-to-weight ratio and higher tear resistance-to-weight ratio than traditional materials, and may be applied in a wide field of potential uses. A non-woven composite material comprises at least one waterproof breathable (W/B) membrane, a first unidirectional non-woven composite layer having multiple fibers enclosed by adhesive in parallel to each other, a second unidirectional non-woven composite layer having multiple fibers enclosed in adhesive in parallel to each other. The first unidirectional non-woven composite layer is positioned such that the fibers are oriented 90° relative to the fibers of the second unidirectional non-woven composite layer, and a space is formed between the first and second multiple fibers. No adhesive is present in the space.
摘要:
A system for providing improved flexible-composite materials, equipment, and manufacturing processes including improved flexible composite materials is disclosed. In various embodiments, a method of manufacturing a flexible laminate composite can comprise performing surface-energy modification on a low-surface-energy fabric, and coating the low-surface-energy fabric with an adhesive. The method can further include at least partially curing the adhesive to the low-surface-energy fabric. The at least partially curing may use at least one of heated rolls, ovens, vacuum ovens, using light, infrared, autoclaving, or ultraviolet curing. Moreover, the method can produce a flexible laminate composite that is fully or substantially impregnated with adhesive material. A flexible laminate composite can comprise a low-surface-energy fabric subjected to a surface-energy modification, and an adhesive material impregnated within the low-surface-energy fabric. The low-surface-energy fabric can be a polyethylene material, which may or may not be a woven fabric.
