An assembly system includes a fixture configured to support a structure including at least one component to receive a malleable material, and a bladder system coupled to the fixture. The bladder system includes a hollowed frame having sidewalls that support a bladder disposed therein. The hollowed frame has an opening that exposes an outer portion of the bladder and is configured to guide the exposed outer portion externally from the hollowed frame toward a targeted area of the structure. In response to inflating the bladder, the outer portion of the bladder extends through the opening and applies a force against the at least one component so as to form a design feature element from the malleable material.

The present invention is directed to an acoustical baffle that has use in vehicle interiors, such as an interior headliner. In particular, the baffle can provide improved acoustics while maintaining a desired airflow resistance and can be configured to provide for different sound attenuation characteristics at selected locations of the baffle construction.

A method for curing a composite including a thermoset resin, a reinforcement material and a thermoplastic additive, the thermoplastic additive having a melt onset temperature, the method including heating the composite to increase a resin temperature of the thermoset resin and, during the heating, controlling the resin temperature such that the resin temperature exceeds the melt onset temperature prior to the thermoset resin achieving a degree of cure of 98 percent.

A method for preparing a polyurethane composite by a vacuum infusion process, a polyurethane composite prepared by said method and use thereof. The method for preparing a polyurethane composite by a vacuum infusion process of the present invention can reduce raw materials and production costs.

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 shear web mould system for manufacturing a wind turbine component in form of an I-shaped shear web having a web body and a first web foot flange at a first end of the web body and a second web foot flange at a second end of the web body is described. The system comprises a central moulding portion for forming at least a part of the web body, a first moulding plate for forming at least a part of the first web foot flange, and a second moulding plate for forming at least a part of the second web foot flange. The angles of the first moulding plate and the second moulding plate relative to the central moulding portion are adjustable.

An airfoil for a gas turbine engine defining a spanwise direction, a root end, a tip end, a leading edge end, and trailing edge end is provided. The airfoil includes: a body extending along the spanwise direction between the root end and the tip end, the body formed of a composite material; and a sculpted leading edge member attached to the body positioned at the leading edge end of the airfoil, the sculped leading edge member formed at least in part of a metal material and defining a non-linear patterned leading edge of the airfoil.

An assembly system includes a fixture configured to support a structure including at least one component to receive a malleable material, and a bladder system coupled to the fixture. The bladder system includes a hollowed frame having sidewalls that support a bladder disposed therein. The hollowed frame has an opening that exposes an outer portion of the bladder and is configured to guide the exposed outer portion externally from the hollowed frame toward a targeted area of the structure. In response to inflating the bladder, the outer portion of the bladder extends through the opening and applies a force against the at least one component so as to form a design feature element from the malleable material.

A method of manufacturing a foam molded product having a reinforcement layer including a short fiber provided on a surface layer. The method includes the following steps. In a fiber layer formation step, the short fiber is adhered to and deposited on a cavity surface of a mold to form a fiber layer. In a covering step, a silicone rubber sheet is arranged on the mold to cover the fiber layer. In a compression step, air is sucked between the silicone rubber sheet and the cavity surface to compress the fiber layer by the silicone rubber sheet and the cavity surface. In a molding preparation step, the silicone rubber sheet is removed from the fiber layer after compression, a foam material is suppled into a cavity of the mold, and the mold is clamped. In a molding step, the foam material in the cavity is foamed and cured.

The disclosure provides a material layer forming device that can reduce scattering of a raw material blown out from a nozzle to efficiently deposit the raw material on a required portion of a blowout target surface. A fiber layer forming device 1A is a device that blows out short fibers F1 to a blowout target surface (wall surface 4b) and deposits the short fibers F1 on the blowout target surface to form a sheet-like fiber layer F2. The fiber layer forming device 1A includes a nozzle 10 having a blowout region 11c that blows out the short fibers F1. The nozzle 10 further includes a suction region 12c that is close to the blowout region 11c and sucks the short fibers F1 spreading to the outside of the blowout region 11c, among the short fibers F1 blown out from the blowout region 11c.
