A multi-part compression mold for forming a complex part having a desired fiber alignment, and methods therefor, are disclosed. The multi-part mold comprises at least three sections. Specific arrangements of fiber-bundle-based preforms are introduced to more than one of the mold sections of the multi-part mold, and subjected to compression molding. The arrangements of preforms, in conjunction with the multi-part mold, result in a complex part having fibers that substantially align with anticipated principle stress vectors that arise in the complex part, when in use.

A method for producing a channel-shaped hollow profile component from a nonwoven material includes providing first and second nonwoven material layers arranging the first and second nonwoven material layers in a mold tool having first and second mold tool halves and a core body wherein a formation of the first and second nonwoven material layers and the core body is arranged between the first and second mold tool halves, and wherein the core body is arranged between the first and second nonwoven material layers in the formation, and simultaneously forming the first and second nonwoven material layers in the mold tool to form a first nonwoven partial shell and a second nonwoven partial shell.

A method for manufacturing a thrust reverser blocker door may comprise thermoforming a sandwich panel comprising a facesheet, a backsheet, and a honeycomb core. The method may further comprising overmolding a mounting structure onto the backsheet. The first thermoplastic material may comprise a continuous fiber reinforced thermoplastic composite material. The second thermoplastic material may comprise a discontinuous fiber reinforced thermoplastic composite material.

A rubber tube has an inner surface at least partly roughed so that the ratio (Rz/D) of the maximum height Rz of the inner surface to the inner diameter D of the tube is not less than 0.038. The ratio (Rp/D) of the maximum peak height Rp of the inner surface to the inner diameter D of the tube may be not less than 0.019. The ratio (Rv/D) of the maximum valley depth Rv of the inner surface to the inner diameter D of the tube may be not less than 0.019. The ratio (Ra/D) of the arithmetic average roughness Ra of the inner surface to the inner diameter D of the tube may be not less than 0.0036. The ratio (Rq/D) of the root mean square height Rq of the inner surface to the inner diameter D of the tube maybe not less than 0.0046. Thus, the rubber tube has a reduced adhesiveness.

A matched compression die apparatus comprising an additively manufactured core member and an additively manufactured cavity member may be used to manufacture compression-molded parts, such as thermoset and/or thermoplastic panels for aircraft interiors. The apparatus may include generic frame structures configured to support different additively manufactured core and cavity members configured for molding different panels. The additively manufactured core and cavity members may be made of metal and/or a polymer material. The apparatus may include a heating mechanism (e.g., heat blankets) configured to heat the core and cavity members sufficiently to mold a workpiece into a desired shape.

A thrust reverser blocker door includes a body portion and a mounting structure coupled to the body portion. The body portion includes a facesheet, a backsheet, and a honeycomb core. The facesheet and/or the backsheet comprises a first thermoplastic material and the mounting structure comprises a second thermoplastic material. A method for manufacturing a thrust reverser blocker door may comprise thermoforming a sandwich panel comprising a facesheet, a backsheet, and a honeycomb core. The method may further comprising overmolding a mounting structure onto the backsheet. The first thermoplastic material may comprise a continuous fiber reinforced thermoplastic composite material. The second thermoplastic material may comprise a discontinuous fiber reinforced thermoplastic composite material.

Tooling for use in forming a variable taper component is provided. The tooling includes an inner mandrel and an outer mandrel disposed around the inner mandrel. The inner mandrel includes a master insert defining opposed tapered edge faces, an external surface having a variable taper and a plurality of recesses configured to receive at least a portion of the variable taper component, and a tapered internal surface. The inner mandrel also includes a plurality of interlocking pieces arranged concentrically around the master insert, and a tapered inner sleeve disposed against the tapered internal surfaces of the plurality of interlocking pieces and the master insert. The outer mandrel defines a corresponding plurality of recesses configured to receive at least a portion of the variable taper component, wherein a maximum width of the interlocking pieces and the master insert is smaller than a minimum width of ends of the variable taper component.

The invention relates to a method and a device for manufacturing an articular prosthesis implant using a mould comprising a ceramic imprint (1) moved by a piston (2), the ceramic imprint (1) pressing the thermoplastic material introduced into the mould.

This disclosure is directed to a thermoplastic composite material forming method and tooling used to perform the method. More specifically, this disclosure is directed to a method of fabricating large, complex thermoplastic composite part shapes with a consolidation tool having a conformable tooling bladder that heat thermoplastic material in the tool and provide thermoplastic material consolidation pressure in directions in the tool to form a part shape of thermoplastic composite material. A novel tooling concept is used to fabricate large, complex thermoplastic composite part shapes which are not easily producible using traditional methods. The tooling concept employs a consolidation tool that provides a method to apply thermoplastic material consolidation pressure by a conformable tooling bladder that provides thermoplastic material consolidation pressure in directions in the tool that are not achievable by conventional clamshell type molds where the mold parts move in substantially vertical tool opening and tool closing directions.

The present invention relates to a method and a structure for attaching nonslip members to both sides of a sock, in which nonslip members having a variety of patterns may be firmly attached to an inner side and an outer side of a sock, which need a nonslip member, using a mold, the nonslip member includes air holes to be smoothly ventilated, and a size of the nonslip member is adequately adjusted according to a thickness and an area of the mold.
