A thermoforming trim tool which comprises a punch side and a die side. The punch side moves to the die side in order to trim molded articles from a heated thermoforming sheet that is disposed therebetween. While the punch side of the tool comprises a plurality of punches, the die side of the tool comprises a plurality of dies, and both the punches and the dies are engaged with upper mount plates. Each of the upper mount plates is engaged with a lower mount plate via one or more location keys. Each of the location keys is configured to provide that the upper mount plates are shifted a pre-determined distance relative to the lower mount plate, thereby providing trim centers which are adjusted to account for pre-determined shrinkage in the sheet.

In one aspect, there is a method of making a composite skin for a tiltrotor aircraft including providing a first skin in a mold, the first skin having a periphery defined by a forward edge, an aft edge, and outboard ends; providing a plurality of honeycomb panels having an array of large cells onto the first skin, each cell having a width of at least 1 cm; assembling the plurality of honeycomb panels along the longitudinal axis of the first skin to form a honeycomb core having an outer perimeter within the periphery of the first skin; positioning a second skin onto the honeycomb core, the second skin having an outer perimeter within the periphery of the first skin; and curing an adhesive to create a bond between the first skin, the honeycomb core, and the second skin to form a composite skin.

A modular plastic pipe formation apparatus, wherein at least two components of the pipe formation apparatus are disposed with respect to at least one or more respective modules.

A hollow body molding device forming a hollow molded body in a main cavity of a mold having in its one end a pressure port including a floating core by injecting molten resin through an injection gate into the main cavity having an outlet, and then pressure-injecting pressurized fluid through the pressure port into the main cavity to move the core toward the outlet through the resin injected into the main cavity to extrude the resin through the outlet and discharge it into a waste cavity, the device having: a floating core accommodating portion located between the outlet and a communication passage leading to the waste cavity and adjoins the main cavity and accommodates the core moved to the outlet by the fluid, in the device, a floating core accommodating portion inside diameter is smaller than a main cavity outlet diameter and is larger than a floating core outside diameter.

A vehicle running board includes opposing vertical walls extending along a length of a tubular structure and including a carbon-fiber component. Opposing horizontal walls extend between the opposing vertical walls and include a glass component. The opposing vertical and opposing horizontal walls form the tubular structure having a generally rectilinear cross section. A polymer outer covering extends over the opposing vertical and opposing horizontal walls.

A manufacturing method of a polishing layer is provided. First, a mold for which the mold cavity has a contour pattern is provided, and the cross section of the contour pattern along a direction includes a plurality of recessions and at least one concavity portion, wherein the at least one concavity portion is disposed on the bottom of at least one of the recessions. A polymer material is disposed in the mold cavity. The polymer material is cured to form a semifinished product, wherein the cross section of the semifinished product along the direction includes a plurality of polishing portions corresponding to the recessions and at least one protruding portion corresponding to the at least one concavity portion. A flattening process is performed on the semifinished product to remove the at least one protruding portion.

Disclosed herein is a composite piston pin including a pipe-shaped outer layer made of reinforced fibers; an inner layer coupled to the outer layer along an inner surface of the outer layer, and made of reinforced fibers having lower elasticity than the outer layer; and a resin material including an epoxy resin composition and cyanate ester, and impregnated into the reinforced fibers of the outer layer and the inner layer.

A zero-Poisson-ratio honeycomb structure and an interlocking assembly manufacturing method thereof are provided. The honeycomb structure is formed by combining a four-pointed star shaped structure and horizontal and vertical honeycomb wall arrays at star corners. The zero-Poisson-ratio honeycomb structure not only has the zero-Poisson-ratio characteristic, but also can achieve respective design of in-plane and out-of-plane mechanical properties. Meanwhile, due to the existence of the horizontal honeycomb walls and the vertical honeycomb walls, the connection of multiple honeycomb walls at angular points in the honeycomb structure is avoided. Moreover, a novel manufacturing mode is provided for the honeycomb structure in addition to prepare the honeycomb structure by utilizing a 3D printing process. The honeycomb structure can be manufactured by combining an interlocking assembly process with resin matrix composites. The performance of the honeycomb structure is further improved at the material level.

A method for forming an article includes providing a sheet of material, optionally conditioning the sheet with a surface of a roller, forming the sheet to provide a web, and separating an article from the web to provide the article. An apparatus adapted to form the article from a sheet is provided.

There is provided a laminate in which when the protective plate breaks due to an impact, not only the scattering of large broken pieces but the scattering of powdery fine broken pieces can be suppressed. A laminate including an adherend and an adjacent layer, wherein the adherend has a first major surface, a second major surface being a back surface of the first major surface, and a lateral surface connecting an edge of the first major surface and an edge of the second major surface, at least the first major surface and the lateral surface of the adherend are covered with the adjacent layer, the adjacent layer has at least a plastic film and a hard coat layer containing a cured product of a curable resin composition in this order from the adherend side, and a softening point F1 of the plastic film and a softening point F2 of the hard coat layer satisfy a relationship of F1<F2.
