A fiber-reinforced composite material having at least one reinforcement layer having one or more woven mats, unwoven mats, or bundle of fibers comprising a plurality of reinforcement fibers that has a binder-resin filling at least a portion of the voids of the reinforcement fibers. In some aspects, the binder-resin adheres to the reinforcement fibers and displaces the air voids at the interface between the reinforcement fibers and the binder-resin. The binder-resin has a relatively low viscosity less than at least about 20,000 centipoise at 176° C. and low molecular weight, which allows the reinforcement layer to maintain a low flex modulus while maintaining or increasing tensile modulus. The fiber-reinforced composite material can be utilized in various articles, such as a flexible fiber reinforced hose adapted for conveying fluids under pressure having at least one polymer layer that bonds to the binder-resin of the reinforcement layer, preferably being cross-linkable or cross-linked to the polymer layer.

A flexible fiber reinforced hose adapted for conveying fluids under pressure. The reinforced hose having a core tube having at least one reinforcement layer surrounding an outer core tube surface. Each reinforcement layer having one or more woven mats, unwoven mats, or bundle of fibers comprising a plurality of reinforcement fibers that has a binder-resin filling at least a portion of the voids of the reinforcement fibers. In some aspects, the binder-resin adheres to the reinforcement fibers and displaces the air voids at the interface between the reinforcement fibers and the binder-resin. The binder-resin has a relatively low viscosity less than at least about 20,000 centipoise at 176° C. and low molecular weight, which allows the reinforcement layer to maintain a low flex modulus while maintaining or increasing tensile modulus. The reinforced hose also has at least one polymer layer that bonds to the binder-resin of the reinforcement layer, preferably being cross-linkable or cross-linked to the polymer layer.

A coextruded plastic spring member is disclosed which is bendably disposable between first and second member to create a spring force therebetween. The spring member includes an elongated base formed from a first plastic material which is engageable by the first member. An elongated first spring portion formed from a second plastic material that is resilient and has a predetermined spring characteristic is coextruded with the base member. An elongated second spring portion is coextruded with and extends from the first spring portion and is formed from a third plastic material having a spring characteristic stiffer than that of the first spring portion, with the second spring portion being engageable by the second member. The first and second spring portions are constructed so that the first spring portion is under compressive loading when the second spring portion is bendably engaged by the second member.

Spring member

A jamb liner for a double hung window wherein a length of the jamb liner is mounted to and overlies each of the jamb sides defining the window opening. Each jamb liner has a front profile corresponding to the side of the associated sash to slidably retain and guide the sash. The jamb liner is extruded from a plastic material that is at least semi-rigid. Coextruded on the rear face of the jamb liner is are a pair of longitudinal spring hinge members each having a first portion contiguous with the jamb liner formed from a resilient material having a spring characteristic, and a second portion extending from the first portion formed from a plastic material that is at least semi-rigid. In mounting the window assembly into the jamb opening, the spring hinge members bendably and springably engage the associated jamb sides to generate a uniform biasing force on the sides of the sashes.
