The present invention relates to high quality composite materials from fibrous materials, in which the composite incorporates a polymer matrix embedding individual fibers. The matrix is derived from polymer particles which penetrate into a strand and substantially fill gaps between individual fibers. Such penetration can occur by exposing the strand to a stable emulsion of the polymer particles. The invention also relates to novel composite structures which incorporation of various types of fibrous segments. These composite structures allow the use of inexpensive and readily available scrap materials. The composites of the present invention are lightweight materials displaying enhanced strength and durability.

Hybrid composite articles and methods for their production

The present invention relates to high quality composite materials from fibers such as glass, polyaramid or graphite fibers, where the composite incorporates a polymer matrix embedding individual fibers. The composites are lightweight materials displaying enhanced strength and durability. In one aspect, the polymer matrix is a thermoplastic or other polymer type that cannot easily penetrate gaps between individual fibers by typical methods for thermosets. The invention also relates to methods for forming composite materials, where the fiber is exposed to an emulsion including polymer particles having sufficiently small dimensions to allow impregnation into the fiber gaps. Composite sheets and articles are also described, as well as the formation of new composites for porous articles, e.g., ceramics or wood, where a polymer matrix is embedded within the pores.

A movable barrier wall system includes a housing assembly that has an interior chamber A barrier member is made of a buoyant material having a selected density. The barrier member floats vertically within the chamber when a liquid is present. The barrier member may be made from a closed cell foam core that is clad with a fiberglass mesh material then the assembly is infused with a resin material. Alternatively, the core may be made from a plurality of elongated rods that are individually clad and reinforced with a shear layer. The individual barrier member modules may be assembled in an end to end relationship with an elongated vertical seal member therebetween. The barrier member may be selectively raised prior to and in anticipation of a flood situation of a nearby body of water by a pump and control system that may be automatically or manually controlled. At least one passive backup system is provided for filling the chamber when the pump or control system fails. The system includes a second pump for selective removal of the liquid from the chamber
