A method for forming a preform charge having a complex geometry includes determining a partitioning axis defining first and second portions the preform charge, each portion having a major segment and a minor segment that are not co-planar with each other, creating a fixture having segregable elements that form cavities for partially consolidating the major segments of the first and second portions, and a cavity for partially consolidating the minor segments, separately partially consolidating the major segments, and, while partially consolidating the major segments to one another, forming the minor segments and partially consolidating them to the major segments. And a fixture capable of carrying out the method.

A method useful for forming a composite part having regions in which fibers align with the principle stress vectors as well as regions having a randomized fiber alignment. To form the randomized fiber alignment, a preform cavity is formed in a preform arrangement, and the preform arrangement is molded in accordance with compression molding protocols to form a part.

Multicomposite material (R1, R2) including at least one monofilament (10) made of glass-resin composite including glass filaments (101) embedded in a thermoset polyester resin (102), this monofilament being covered with at least two superposed layers of different materials, a first layer (12) arranged on the surface of the monofilament and a second layer (14) of polyester thermoplastic material sheathing the whole, characterized in that the first layer (12) is a layer of benzoxazine and/or polybenzoxazine; finished articles or semi-finished products made of rubber, such as vehicle tyres, reinforced with such a material.

This specification discloses an article of manufacture. The article of manufacture has at least one structural blank and at least one guide. The structural blank has a plurality of oriented fiber plies in a thermoplastic matrix. The guide has a plurality of random dispersed fibers in a thermoplastic matrix. The guide is affixed to the structural blank by injection molding and over molding the guide onto the structural blank. The article of manufacture can take a number of forms for use in industries such as aircraft, automobiles, motorcycles, bicycles, trains or watercraft.

A reinforced substrate is provided for use in molding a composite material. The reinforced substrate has a reinforcing layer having reinforcing fibers extending in a fiber direction that is aligned in a single direction and auxiliary fibers laminated on only one surface of the reinforcing layer so as to extend in only one direction that intersects with the fiber direction. The auxiliary fibers are joined to the reinforcing fibers to hold the reinforcing layer. The auxiliary fibers have a higher tensile elongation at break than do the reinforcing fibers. The reinforcing layer is arranged with fiber bundles of large tows being aligned in an unopened state. The large tows have a higher fiber count of the reinforcing fibers than does a regular tow.

Disclosed herein a method and equipment for making a unidirectional continuous fiber-reinforced resin composite material. A resin plasticized and molten by an extruder is transported to a coating guide roller through a die head, and a hot-melt resin film layer with uniform thickness is formed on a roller surface of the coating guide roller. Simultaneously, the coating guide roller guides the hot-melt resin to continuously and uniformly coat on a row of flattened unidirectional continuous fibers along the roller surface of the coating guide roller. Subsequently, the coated flattened unidirectional continuous fibers pass through an open dip-coating roller device to effectively combine with the hot-melt resin to obtain a composite material of the hot-melt resin and fibers, which passes through a cooling and forming device to a winder under a driving force of the main traction to obtain the unidirectional continuous fiber-reinforced resin composite material.
