A method of forming a component having grooves formed into an outer surface of a component includes the steps of applying at least one mold to an outer surface of a component preform. The mold is forced into contact with the outer surface to form a detent into the outer surface.

A tooling assembly, including an elongated ceramic member having a distal end and an oppositely disposed proximal end, a plurality of spaced protuberances extending from the elongated proximal end, at least one groove formed in the proximal end, and an elongated polymer member enveloping the distal end. The overlap of the elongated polymer member and the elongated ceramic member defines a joint. The joint has a tensile strength of at least 11121 Newtons.

The present disclosure encompasses three-dimensional articles comprising flexible-composite materials and methods of manufacturing said three-dimensional articles. More particularly, the present system relates to methods for manufacturing seamless three-dimensional-shaped articles usable for such finished products as airbags/inflatable structures, bags, shoes, and similar three-dimensional products. A preferred manufacturing process combines composite molding methods with specific precursor materials to form fiber-reinforced continuous shaped articles that are flexible and collapsible.

The purpose of the present invention is to obtain a fiber-reinforced composite material molded article having high adhesive strength in a boundary portion between an insert portion comprising a fiber-reinforced resin substrate and an integrally molded portion molded integrally with the insert portion. A fiber-reinforced composite material molded article (1) containing reinforcing fibers and a thermoplastic resin and being provided with a first layer (23), a second layer (22), and a third layer (21) in this order, the thickness of each layer, the ratio of the total volume of reinforcing fibers (x2) having a fiber length of 3 mm to less than 100 mm with respect to the total volume of reinforcing fibers present in the layer, the ratio of the total volume of reinforcing fibers (y2) having a fiber length of 0.02 mm to less than 3 mm with respect to the total volume of reinforcing fibers present in the layer, and the volume content of fibers in each layer being controlled so as to be in specific ranges.

Interface for fastening a first component to a second component providing a fastening collar made from composite material intended to be overmoulded at least on a part of the first component and including a bearing surface intended to bear on the second component and a fastening insert extending along an axis of elongation substantially perpendicular to the bearing surface of the collar for fastening to the second component, the fastening collar being overmoulded around the insert.

Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.

The invention relates to a method for preparing a fiber-reinforced article, having attached to at least part of its surface a layer of a material that is not fiber-reinforced, comprising the steps of 1) preparing a shell via an additive manufacturing technique, the shellbeing of a material that is not fiber-reinforced; andhaving a surface that corresponds in negative relief to a surface of the article formed in step 3); thereafter 10 2) applyinglong and/or continuous reinforcement fibers; anda curable resin to the surface of the shell that is in negative relief, to form a mixture of curable resin and long and/or continuous reinforcement fibers on the 1 surface of the shell, so that the surface of the mixture contacting the shell adopts the shape of the surface of the shell that is in negative relief; thereafter 3) curing the curable resin to form the fiber-reinforced article having attached to at least part of its surface a layer of a material that is not 20 fiber-reinforced.

A method of forming a component having grooves formed into an outer surface of a component includes the steps of applying at least one mold to an outer surface of a component preform. The mold is forced into contact with the outer surface to form a detent into the outer surface.

A system and method for forming 3D printed structures includes printing an outer shell portion and filling an interior of the outer shell portion to form an inner portion. The outer shell portion and inner portion may have differing material properties. The outer shell portion may be anchored to the base component.

A molding process and device produce a hybrid composite part. The process includes configuring a mold cavity (102) to receive a prepreg material (116), configuring the mold cavity further to receive an injection of material, and providing a mold core (104) including at least one main core (112). The at least one main core (112) are configured to move with respect to the mold core (104). The process includes moving the mold core (104) with respect to the mold cavity (102) with a first actuator mechanism, moving the mold core to take a first configuration, forming with the mold core in the first configuration a preform from the prepreg material, moving the mold core to take a second configuration, and over molding onto the preform with the injection of the material with the mold core in the second configuration.
