摘要:
The invention concerns a process for making a scrim-reinforced prepreg for use in building low-porosity lay-ups, characterized in that a conventional prepreg is formed of a fibrous reinforcement and a heat-curable resin, the prepreg having suitable viscosity and sufficient tackiness to hold a scrim which is adhered to the prepreg by applying light pressure, so that the scrim is impressed onto the prepreg to such a degree, that less than half of the circumference of the scrim strands becomes coated by the prepreg-resin.

In one aspect, the present invention is a thin-layer lignocellulose composite having increased resistance to moisture. The thin-layer lignocellulosic composite includes a mixture of no more than about 95% by weight of a lignocellulosic fiber and at least about 5% by weight of an organic isocyanate resin. The mixture further includes short fibers and a release agent that does not interfere with subsequent processing of the thin-layer lignocellulosic composite. The mixture is pressed between two dies at an elevated temperature and pressure and for a sufficient time to form a thin-layer composite of predetermined thickness, and to allow the isocyanate resin to interact with the lignocellulosic fiber and short fibers such that the resultant thin-layer composite has a predetermined resistance to moisture.

A seaming system for forming a seam is disclosed, wherein the seam consists of at least two opposed sections of high-modulus, high-tenacity, low-elongation fabric sections joined by a tape. The system comprises a seamer head, and a seamer base that includes a topography configured to impart a predetermined pressure gradient to the adhesive layer, tape, and fabric sections of the seam. The resultant seam has a cross-section or thickness profile that generally corresponds to that of the applied pressure gradient. As such, the constructed seam more efficiently distributes stress imparted from any applied load.

Disclosed herein are embodiments of a multi-layer nonwoven fiber material, and related methods of manufacturing the material. In one exemplary embodiment, the fiber material includes a first layer of directionally aligned fibers together with a second layer of randomly dispersed fibers dispersed over the first layer. Consistent with one exemplary method for manufacturing a nonwoven fiber material, the method includes dispersing a first plurality of fibers horizontally in one or more predetermined directions, as well as dispersing a second plurality of fibers horizontally in random directions. In such an embodiment, the second plurality of fibers is dispersed over the first plurality of fibers. Moreover, an exemplary embodiment of a roofing shingle employing a nonwoven fiber material as described herein is as disclosed.

A method for producing a stretch laminate includes forming an intermediate stretch laminate. Forming the intermediate stretch laminate includes providing a first substrate and attaching an elastic film to a surface of the first substrate via an adhesive. The first substrate and the elastic film are in a face to face orientation. The intermediate stretch laminate has a residual energy of greater than or equal to 50% at a predetermined applied strain. The method of forming the stretch laminate further includes mechanically activating the intermediate stretch laminate at a strain rate of at least 100 s−1.
