The disclosure provides an interior trim part for a motor vehicle having a sliding or panoramic roof comprising a headliner and a stiffening frame attached to the headliner and enclosing and stabilizing an opening in the headliner enclosing the sliding or panoramic window, the stiffening frame being made of a fiber-reinforced composite material comprising a fiber mat and a textile lattice material, the textile lattice material being applied over a surface of the fiber mat and impregnated together therewith.

A manufacturing method of a long fiber composite material according to an exemplary embodiment of the present invention includes: preparing a main body where inlets and outlets through which a plurality of fiber bundles are respectively charged into and discharged from are formed; adjusting a height of a plurality of first through-hole plates and a height of a second through-hole plate that are disposed in the main body to be the same; having the plurality of fiber bundles penetrated through the first through-hole plate and the second through-hole plate; and adjusting the height of the first through-hole plate and the height of the second through-hole plate to be different from each other after penetrating the plurality of fiber bundles through the first through-hole plate and the second through-hole plate.

A method for manufacturing an alveolar core structure includes at least one cell including a secondary duct having a first end defining a sound wave inlet, and an opposite second end, the secondary duct comprising a sound wave outlet. The method also includes a fastening step in which adhesive tapes transverse to the longitudinal direction of said first plate are applied on a first longitudinal plate. The secondary duct in the form of a flattened element is fastened, on the first plate, by gluing at its sound wave inlet. A second plate is applied. A step of deploying the first and second plates so as to form the peripheral wall of the cells and so that the flattened element is deployed.

A prepreg includes composition elements [A], [B], and [C] described below,

[A] a reinforcing fiber,

[B] a thermosetting resin, and

[C] a thermoplastic resin.

[B] contains a thermoplastic resin having an aromatic ring with an amount of 10% or more by mass, a resin region containing [B] is present on one surface of the prepreg, a resin region containing [C] is present on another surface of the prepreg, and [A] that crosses over a boundary surface between the resin region containing [B] and the resin region containing [C] and that is in contact with both resin regions is present.

A fiber-reinforced resin composite sheet of the present invention contains: a polyamide resin film containing a dicarboxylic acid component (a) and a diamine component (b); and a plurality of reinforcing fibers laminated in a state of being oriented in the same direction on the polyamide resin film, the reinforcing fibers being obtained by opening a reinforcing fiber bundle. The dicarboxylic acid component (a) contains 60 mol % or more and 100 mol % or less of terephthalic acid. The diamine component (b) contains 60 mol % or more and 100 mol % or less of 1,9-nonanediamine and 2-methyl-1,8 octanediamine. The fiber-reinforced resin composite sheet has a volume content rate Vf of the reinforcing fibers of 20% or more and 70% or less and a thickness of 20 μm or more and 70 μm or less.

Provided are methods and devices for supporting of variety of different pre-cured composite stringers after forming and prior to curing. A post-forming processing device comprises a base with a channel for receiving hat portions of different stringers. The device also comprises a support structure, at least partially extending within the channel. The support structure is configured to conform to different hat portions and to retain the shape of these hat portions. For example, the support structure is made from a flexible material, which conforms to any shape variations. In some examples, the support structure is made from a jamming material that is reshaped together with each of the pre-cured composite stringers. A post-forming processing device is used for supporting different pre-cured composite stringers while various operations are performed on these stringers, such as stringer trimming, inspection, installation of bladders and noodles, and the like.

A pulling device is provided for a pultrusion device, having at least one clamping device that can be moved in a pultrusion direction. The clamping device is designed to frictionally seize a pultruded profiled strand to be conveyed, in order to apply a tensile force to the profiled strand. The clamping device has at least three clamping jaws that can be moved in relation to each other, for peripherally clamping the profiled strand.

The present invention provides an apparatus for recycling composite material and a method for recycling composite material by using same, the apparatus including: a mixing tank in which pulverized products of fiber-reinforced waste plastic are dispersed and mixed in water together with a filler, thereby forming a composite material mixture; a fixing agent addition part for forming a recyclable material by supplying, to the composite material mixture, a fixing agent that aggregates the pulverized products of the fiber-reinforced waste plastic and the filler; and a filtering tank in which the recyclable material is supplied such that a recyclable composite sheet is formed.

A method of forming a headliner for a vehicle includes forming the headliner into a desired shape from one or more materials. The headliner includes a headliner cutout portion corresponding to an opening through the headliner. A reinforcement bracket preform is formed into the headliner cutout portion during the step of forming the headliner. The headliner cutout portion is removed from the headliner. The reinforcement bracket preform is removed from the headliner cutout portion and a shaped reinforcement bracket is formed.
