The invention relates to a method for producing a self-reinforced thermoplastic composite material including: providing strips of a thermoplastic and weaving the plastic strips into a base fabric. The plastic strips for this are produced by at least the following steps: producing pre-stretched fibres from a partially crystalline polyester homopolymer with a melting point by extrusion on at least one spinning nozzle and subsequent stretching and joining a plurality of pre-stretched endless fibres lying next to and/or above one another to a matrix of an amorphous polyester homopolymer at a processing temperature T2<T1, wherein the temperature difference between T1 and T2 is at least ΔT=30° C.

A seat support element has a body that includes at least one portion having a plurality of discrete structural elements and a plurality of connecting fibers, the discrete structural elements being joined together via the connecting fibers to form the portion of the body.

A panel for a vehicle includes a core formed from fibers and a thermoset resin. The panel also includes a first barrier layer positioned on a first side of the core and a second barrier layer positioned on a second side of the core, opposite the first side. Each of the first and second barrier layers is configured to block flow of the thermoset resin from the core during a panel forming process.

A composite includes a heavy Leno weave fabric, a first resin coating, and a second resin coating. The heavy Leno weave fabric has a first side and a second side. The fabric is characterized by yarns having a denier number of at least about 1,300 in both warp and weft directions. The fabric defines a pore structure. The first resin coating is on the first side of the heavy Leno weave fabric. The second resin coating is on the second side of the heavy Leno weave fabric. The first and second resin coatings are bound to each other through the fabric via the pore structure.

The present disclosure relates to a fibre reinforced polymer (FRP) tube, the tube comprising a plurality of concentric layers of an FRP material forming a shell of the tube. At least one blind threaded longitudinal bolt hole is provided from a transverse end surface of the shell. The bolt hole extends in at least three of the plurality of layers, a middle layer encompassing a plane passing through a center of the bolt hole, an inner layer encompassing a plane of an innermost extent of the bolt hole, and an outer layer encompassing a plane of an outermost extent of the bolt hole. The fibre filament of each of the inner and outer layers has been wound at a first angle to the longitudinal axis and the fibre filament of the middle layer has been wound at a second angle to the longitudinal axis.

Certain embodiments described herein are directed to articles that provide less sag. In some examples, the articles can include a fiber reinforced thermoplastic polymer core layer comprising reinforcing fibers and a thermoplastic polymer, and a frim disposed on the fiber reinforced polymer core layer. In certain examples, the frim comprises a film coupled to a scrim comprising an effective basis weight to prevent substantial sag of the article, e.g., during a forming operation.

A blow bottle includes an outer layer and an inner layer, wherein the inner layer has blackness higher than that of the outer layer, and wherein the outer layer has an L* value of 20 or more and 90 or less in an International Commission on Illumination (CIE) L*a*b* color system.

A preform is provided for blow-molding to form a container. The preform includes a finish portion for rotatably engaging a closure to seal pressurized contents within an interior of the container. The finish portion comprises a cylindrical body that begins at an opening to the interior and extends to and includes a tamper evidence ledge. A bevel at a beginning of the opening receives a plug seal of the closure. Multiple mirror polished surfaces beyond the bevel are configured to cooperate with the plug seal to seal the container. Mirror polished transition surfaces are disposed between diameter changes within the finish portion. In some embodiments, wherein the plug seal includes a sidewall profile that mates with the transition surfaces, an interior surface of the preform has a diameter that tightly compresses an end of the plug seal to contain pressurized contents within the container.

A steering wheel sheath includes a carbon fiber-comprising composite element and a leather element. The composite element forms a notch and a receiving space axially. Two ends of the composite element extend to form two connection portions bending by a predetermined angle. Inner walls of openings at two ends of the leather element form two engaging portions corresponding in position to the two connection portions of the composite element. An adhesive is applied to outer walls of the two connection portions of the composite element or inner walls of the two engaging portions of the leather element; hence, the composite element and the leather element are connected, coupled and fixed together. The customized manufacturing process allows the steering wheel sheath to be mounted by users and enhances overall feel.
