Kits and methods for fiber composites including partially-cured resinous materials for the reinforcement of physical structures

A composite system for the reinforcement of physical structures includes a plurality of unidirectional fibers arranged with respective longitudinal axes generally parallel to each other over a substantial portion of a length of each unidirectional fiber. The plurality of unidirectional fibers are non-mechanically connected. A resinous material adheres the plurality of unidirectional fibers to each other such that each one of the plurality of unidirectional fiber is adhered to at least one adjacent one of the plurality of unidirectional fibers along a substantial portion of the length of the adjacent one of the plurality unidirectional fibers.

METHOD OF MAKING COEXTRUDED, CROSSLINKED POLYOLEFIN FOAM WITH KEE CAP LAYERS

The present disclosure is directed to a physically crosslinked, closed cell continuous multilayer foam structure comprising at least one foam polypropylene/polyethylene layer with a KEE cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam layer composition layer with at least one cap layer composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

Device for impregnation and curing of continuous fibers with resin

An apparatus for preparation of a continuous composite element formed of reinforcement fibers impregnated with a resin that includes photo-initiators for curing. Reinforcement fibers are pulled through a vacuum chamber (110) and then a vertical impregnation chamber (122) where impregnation with the resin occurs. The elongate composite is then deposited onto a rotating wheel of conformation (140). During rotation, a radiation source (146) such as e.g., LEDs (light emitting diodes) are used to activate the photo-initiators and provide at least partial curing of the resin. From the wheel of conformation, the continuous composite element is passed along a vertical course (148) where additional radiation sources (150) activate the photo-initiators and provided additional curing.

A METHOD FOR MOLD-FREE MANUFACTURING OF NATURAL RUBBER ARTICLES

This invention relates to the method for mold-free manufacturing of natural rubber articles. Specifically, the articles can be fabricated in the stereolithography process which eliminates the need of mold making and reduces the process time significantly. The method comprises the steps of (1) preparing prevulcanized latex compound for sulfur and non-sulfur vulcanization; (2) adding processing aid to make the latex compound curable when exposed to laser irradiation, the processing aid includes heat-sensitive polymer and/or carbon material(s); and (3) fabricating of three-dimensional rubber articles by stereolithography process. The process are capable of fabricating complex shapes and internal features. As the said rubber articles contain more than 95% of natural rubber, they are highly flexible and can be translucent in some embodiments.
