A method for producing flakes of a resin thin film including: a step (1) of forming a resin thin film on a substrate film to obtain a multilayer film; a step (2) of pressing the multilayer film by a member having a concavo-convex shape to form cracks in the resin thin film; and a step (3) of stripping the resin thin film from the substrate film to obtain flakes. The step (2) is preferably performed with a pressing pressure of 100 MPa or less. The resin thin film is preferably formed of a cured product of a photocurable liquid crystal composition. The resin thin film is preferably a cholesteric resin layer.

An embodiment system for molding a plurality of plastic composite material panels to be assembled on a vehicle body includes a coextrusion unit configured to manufacture a multi-layered sheet in which a plurality of resin layers are laminated, a thermoforming unit configured to manufacture a forming sheet having a plurality of panel forming portions partitioned by a forming connection portion by thermoforming the multi-layered sheet, a reinforcing source spraying unit configured to spray a reinforcing source in which a fiber material and a polyurethane compound are mixed toward a preset region on the forming sheet, and a press-molding unit configured to press-mold the forming sheet applied with the reinforcing source to manufacture a composite material panel sheet in which a reinforcing layer is formed on the forming sheet.

In one aspect, there is a composite skin for a tiltrotor aircraft including a first skin having a periphery defined by a forward edge, an aft edge, and outboard ends; a second skin; and a honeycomb core disposed between the first skin and the second skin, the honeycomb core comprised of a plurality of honeycomb panels positioned along the longitudinal axis of the first skin, the plurality of honeycomb panels having an array of large cells, each cell having a width of at least 1 cm; wherein the second skin and the honeycomb core have an outer perimeter within the periphery of the first skin.

A method for producing components of an outer skin of a vehicle with a film, which is back-molded at least from one a front side or rear side with clear plastics material, includes subjecting the film to a thermoforming process in order to generate the desired three-dimensional form. The film is subjected to further steps for preparation of the back-molding, including providing the film at least partially with a color layer. The film includes regions, through which other colors are intended to show through and be visible from the front side, or electromagnetic waves are intended to pass. The film may be punched-out in the regions to define punched-out portion in which components are inserted. The components are attached to the film by adhesive and/or overmolding on the rear side.

Systems and methods are provided for fabricating composite parts. One embodiment is a method for fabricating a composite part, the method comprising: reducing a bulk factor of chips of chopped fiber while forming the chips into a pre-consolidated charge; shaping portions of the pre-consolidated charge into shaped volumetric charges that fit within a die; and compression molding the shaped volumetric charges within the die.

An additive manufacturing apparatus includes a first vertically-extending support leg, a second vertically-extending support leg, and a gantry supported on the first and second support legs. The additive manufacturing apparatus also includes a work table movably supported beneath the gantry, a print head supported on the gantry, and a trim head supported on the gantry with the print head.

Systems and methods for forming pellets from mixed plastic materials are disclosed. An example method may include a method for forming pellets from mixed plastic materials without needing to screen or filter the mixed plastic materials. The method may include disposing a mixed plastic material into an extrusion apparatus, advancing the mixed plastic material through a die to form strands, and cutting the strands into a plurality of pellets.

A heat seal device for use in a bag making apparatus includes: a first heat seal member; a second heat seal member facing the first heat seal member; a heater for heating at least one of the first heat seal member or the second heat seal member; a drive mechanism configured to move the first heat seal member towards and away from the second heat seal member so as to releasably sandwich a web between the first and second heat seal members; a sensor disposed to detect acceleration of the first heat seal member; and a measurement part configured to measure a sandwiching time during which the web is sandwiched by the first and second heat seal members based on data from the sensor.

The present disclosure provides a VR face mask and a manufacturing method thereof. The VR face mask includes a mask body, and a first PU covering layer arranged on a surface of the mask body to be attached close to a human face. The mask body includes a mask bottom layer arranged away from the first PU covering layer, and a filling layer arranged between the first PU covering layer and the mask bottom layer.

The invention provides a process of producing an interconnecting multi-layered LVT tile for a modular flooring system, the process comprising the steps of: a) forming abase substrate of plastics material with at least one locating guide by injection moulding; b) coating the back of an LVT surface layer with adhesive; c) aligning the LVT surface layer to a top surface of the base substrate such that the LVT surface layer abuts the or each locating guide of the base substrate; d) press rolling the base substrate and LVT surface layer together to form an oversized blank; and e) punching out an interlock shape from the oversized blank using a punch and die tool.
