In a preferred embodiment, a composite panel with a smooth outer surface, ready for painting with or without addition of primer, may be created by constructing a panel layup assembly upon a mold, the panel layup assembly including a composite panel having a core and a resin formulation, and a release film between the mold and the composite panel, where a smooth release surface of the release film is in contact with the composite panel upon construction; initiating curing of the composite panel at a first temperature within a lowermost ten percent of a curing temperature range of the resin formulation; continuing curing of the composite panel at a second temperature above the lowermost ten percent of the curing temperature range; and completing curing of the composite panel at a third temperature below the second temperature.

A method of manufacturing a garment includes forming a multilayer composition having one or more design elements. The multilayer composition is formed by applying a material that includes the one or more design elements to an elastomeric polymer base layer. The method further includes heating the multilayer composition, and after the multilayer composition has been heated, then aligning each design element with a respective three-dimensional design feature of a three-dimensional mold, and pressing the heated multilayer composition into the three-dimensional mold. The method further includes cooling the pressed heated multilayer composition to form a three-dimensional molded multilayer composition that includes one or more three-dimensional design elements; and forming a three-dimensional garment from the three-dimensional molded multi-layer composition.

A stiffened part formed from at least two members of thermoset composite material including at least one body of a first structure and optionally a second structure. A manufacturing method includes: forming a fibre preform and impregnating each body of the first structure with thermosetting resin or forming a pre-impregnated fibre preform to obtain a body formed from uncured thermosetting composite material supported by a mandrel; optionally partially or fully polymerising at least one body supported by a mandrel; optionally, providing the second structure formed from uncured, partially uncured or fully uncured thermosetting composite material; optionally, depositing a layer of uncured thermosetting adhesive on an area where a fully cured member makes contact with another member of the part; joining the members, each member being juxtaposed with; or stacked upon, at least one other member; fully curing the assembly by heat treatment; removing the mandrel from each fully cured body.

A composite material molded product has a hollow portion, a bent portion, or a curved portion in a transverse section thereof. When the composite material molded product has, for example, a bent portion, a surface on an inside of the bent portion is a pressed surface. A mold includes a pressing body that is thermally expandable and has an outer surface shape corresponding to a shape of a pressed surface, and a mold main body including a cavity accommodating the laminate and the pressing body inside, the cavity including an inner surface shape corresponding to a shape other than the pressed surface. The cavity is sealed in a state that the pressing body is disposed in the cavity. The laminate is accommodated in a molding space formed between an inner surface of the cavity and an outer surface of the pressing body.

A method of fabricating a preform is provided. The method includes disposing a veil over a first mold portion having a three-dimensional shape, the veil including a thermoplastic material and magnetic particles; disposing a fiber tow onto the veil; heating at least a portion of the veil by induction so that the fiber tow becomes coupled to the veil; compressing the fiber tow and the veil toward each other with a second mold portion that has a negative contour relative to the first mold portion; and removing the preform from the first and second mold portions. The preform has the three-dimensional shape and includes the fiber tow coupled to the veil. Preforms prepared by the method are also provided.

Disclosed herein are abrasion resistant flexible hoses and methods for manufacturing such hose. The abrasion resistant elastomeric hose comprises an inner surface and an outer surface, and a abrasion resistant material embedded in the hose at a depth that imparts a three-dimensional pattern at the outer surface of the hose.

An extruded part is formed by extrusion of at least one polymer melt, wherein the polymer melt or polymer melts has/have two melt fronts, which form two material inner edges of the extruded part when the polymer melt or polymer melts is/are in the solidified state; —the two material inner edges are integrally bonded to each other and define a linear binding seam of the extruded part. The binding seam is situated in a connection region of the extruded part; and —the extruded part has at least one fiber grid, which is situated in the connection region of the extruded part and is connected to the extruded part such that the fiber grid bridges the two material inner edges. The extruded part may be a part of a battery housing for a traction battery.

A fender liner that is to be placed in a curved shape along a periphery of a tire of a vehicle includes: a first foam layer that is formed by a first foam body; and a mixed layer that includes a first non-woven fabric and a second foam body that is foamed inside the first non-woven fabric, wherein the first foam body forming the first foam layer is seamless with the second foam body included in the mixed layer.
