Abstract: 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.

Abstract: A continuous forming apparatus of a fiber reinforced composite includes a tension detection mechanism, a drive motor, and a drive control device. The drive control device is configured so that a material roll is rotationally driven in a delivery direction of a reinforced fiber base material during a time period from a time point of end of pressurization in a forming process to a time point of end of a pulling-out process, and is also configured to perform tension control on the reinforced fiber base material based on a detected tension value from the tension detection mechanism and a target tension value, during a time period from a time point of start of the pulling-out process to a time point of end of the pressurization in the forming process in a next forming operation.

The flexible rebar preform includes at least one reinforcement filament, and at least one thermoplastic filament. The at least one reinforcement filament, and the at least one thermoplastic filament are arranged in a selected distribution across a cross-section of the preform. The pultruding machine includes a pulling apparatus, a rebar cutting apparatus, and a bending apparatus. The pultruding machine is configured to heat the flexible rebar preform to a first temperature. The first temperature is greater than or equal to a melt temperature of the thermoplastic filaments. The pulling apparatus is configured to pull the flexible rebar preform through a pultrusion die to form the rebar. The rebar cutting apparatus is configured to cut the rebar at a prespecified length. The bending apparatus is configured to bend the cut rebar to a prespecified bend geometry.

Abstract: A method for producing a reinforcement rod from a fibrous composite material comprising continuous mineral fibers and at least one resin, the resin being mixed with the dry mineral fibers, then wrapped with a strand of material, and the resin then being instantaneous or nearly instantaneously fully cured (e.g., snap cured) to form an optionally round rod with an optionally helical rib. In aspects, a mixture comprising an environmentally friendly and zero or low volatile organic compound (VOC) emitting resin and a resin-curing agent mixture is used. In aspects, helical ribs are added to the surface of the rod in a manner not to disrupt the longitudinal orientation of the core reinforcing mineral fibers. In aspects, ultraviolet irradiators are used to snap cure the reinforcement. When fully cured, corrosion resistant mineral fibers are encapsulated in a corrosion resistant matrix. The process allows for a simplified, condensed, and single operation for producing a corrosion resistant fibrous composite reinforcement rod.

Abstract: Disclosed herein is a transverse tensioning system that comprises a left-side clamping assembly comprising a first left-side clamp element and a second left-side clamp element. The first left-side clamp element and the second left-side clamp element clamp down on the left edge portion of the stack of plies when the stack of plies moves in a feed direction and is shaped between opposing dies. The system also comprises a right-side clamping assembly, spaced apart from the left-side clamping assembly and comprising a first right-side clamp element and a second right-side clamp element. The first right-side clamp element and the second right-side clamp element clamp down on the right edge portion of the stack of plies when the stack of plies moves in the feed direction and is shaped between the opposing dies.
