Embodiments of the present invention provide a self-molding composite system for insulation and covering operations. The self-molding composite system may be cured to form any desired shaped for insulation and covering operations. The composite system comprises one or more layers that may create a rigid layered composite when cured. The one or more layers of the composite system may include a base layer that is a braided, knit, or non-woven fiber based substrate, an interstitial matrix layer, and customizable top coat. The customizable top coat may be a solvent based polymer solution that includes various additives that may include color pigments, additives for additional abrasion protection, additives for thermal protection, and/or additives for creating various textures or visible appearances to the composite system.

Provided is a method for producing a fiber reinforced plastic with which the occurrence of wrinkling or bridging in a convex surface or a concave surface having a large curvature can be suppressed at the same time even if the fiber reinforced plastic has a complicated three-dimensional shape, the method for producing a fiber reinforced plastic, including a step of shaping a prepreg sheet in which continuous fibers are impregnated with a resin material into a three-dimensional shape to produce a fiber reinforced plastic(a); wherein at least a portion of the continuous fibers in an area (X) of the prepreg sheet corresponding to an area (X) in which the fiber reinforced plastic (a) is sheared and deformed is bent in an in-plane direction in advance.

A laminate apparatus for engaging a fluid includes a structural medium made from plies bonded together with a resin. The structural medium defines a fluid facing surface. The laminate apparatus further includes a liner membrane bonded to the fluid facing surface of the structural medium with the resin. The liner membrane has one or more of a desired barrier characteristic and a desired chemical compatibility characteristic with respect to the fluid.

The invention relates to an injection mold (4) for manufacturing a rotary part made of a composite material having outer flanges, comprising a mandrel (2) on which a fiber reinforcement is intended to be held (9) and including a central wall (6) the profile of which matches that of the part to be manufactured and two side plates (8), molding wedges (12) for bearing against a non-covered surface of the fiber reinforcement, and two outer bells (14) for covering the molding wedges and the plates of the mandrel with sealing O-rings (24) being inserted between the bells and the plates of the mandrel, the bells each being provided with an attachment flange (20) for bearing against one another with at least one sealing O-ring (26) inserted therebetween, the attachment flanges of the bells being clamped against one another.

An apparatus is provided for forming a composite laminate. The apparatus comprises a mandrel having a surface on which the composite laminate can be formed. The apparatus further comprises an application surface and a conveyor configured to move a composite material piece that has been cut to a desired shape to the application surface. The apparatus also comprises an actuating mechanism for, when actuated, lifting the application surface upward towards the mandrel to apply the composite material piece to the surface of the mandrel to form at least a portion of the composite laminate on the surface of the mandrel.

Stiffened skin panels comprise alternating truss core portions and solid laminate portions sandwiched between inner and outer facesheets, all formed from a fiber reinforced thermoplastic. The components of the panels are co-consolidated using induction heating. The panels are stiffened with spars fastened to the solid laminate portions.

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; andthe 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 thermal, flame protective sleeve for protecting a member therein and method of construction thereof. The sleeve includes a tubular member having a circumferentially continuous wall with a straight cylindrical inner surface bounding an inner cavity extending along a central longitudinal axis between open opposite ends. At least one end cap is fixed to at least one of the opposite ends. The at least one end cap has at least one resilient tine extending radially inwardly from an outer surface of the end cap sufficiently for engagement with an elongate member extending into the inner cavity of the tubular member. The at least one end cap is silicone.

The present disclosure relates to the development of high performance light weight carbon fiber fabric-electrospun carbon nanofibers hybrid polymer composites and a process thereof. In this process continuous carbon nanofiber sheets of diameter in the range of few hundred nanometers are developed from electrospun PAN nanofibers and sandwich between the carbon fiber fabric epoxy resin prepregs to develop hybrid polymer composites by compression molding technique with low content of carbon fibers.

Disclosed embodiments relate to trays typically comprising a composite internal structure, a thermoplastic frame typically located about the composite internal structure, and two cover sheets forming the upper and lower tray surfaces. The composite internal structure may be a corrugated composite structure in some embodiments. In other embodiments, the composite internal structure may comprise a series of composite elements (which might act a beams or struts). The cover sheets may comprise thermoplastic material, and in some embodiments, the cover sheets may comprise composite material (for example the same as for the corrugated composite structure). In some exemplary embodiments, the thermoplastic frame and the composite internal structure may have the same thermoplastic material, and they may be joined together to have a plurality of homogeneous connective attachments.
