Provided is a method for preparing an electrothermal heating sheet from carbon fiber braided fabric scraps, including: cutting clumps of disordered carbon fiber braided fabric scraps into chopped carbon fibers; washing the chopped carbon fibers by separately using acetone and deionized water, and drying; preparing a corresponding dispersion; adding the chopped carbon fibers to the dispersion, and fully dispersing; performing vacuum filtration by using a double-layer metal screen, and drying to obtain a chopped carbon fiber felt; cutting the chopped carbon fiber felt, sticking electrodes to two ends of the chopped carbon fiber felt, and covering thermoplastic polyurethane (TPU) sheets on front and back surfaces of the chopped carbon fiber felt to form a heating sheet product having electrothermal performance and electromagnetic shielding performance. The direct discarding of the carbon fiber braided fabric scraps and the scraps resulting from cutting in the preparation process as wastes may result in not only great wasting of materials but also in environmental pollution. The method fully utilizes the carbon fiber braided fabric scraps and is low in cost, and the prepared product has excellent electrothermal performance and electromagnetic shielding performance.

Disclosed is a set of lining plates made of radial tires to protect pieces of equipment from abrasion and to absorb impacts where said set of lining plates comprises a plurality of lining plates made of radial tires that are laid out next to each other in order to line the surface of a given equipment. The lining plates that make up the set are fitted with tongues and grooves so as to allow them to be joined together and make it possible for a perfect fixation through special hook-type screws in order to secure an effective sealing of the equipment surface on which said plates were installed, thus preventing any material from entering the space between the lining plates. The present invention also relates to a method for manufacturing the lining plates of the set using radial tires.

A method may include pressing a mat including a blend of paper and plastic fragments by applying a pressure to the mat using a heated press such that the mat is compressed to a first thickness, where the pressure is greater than a critical pressure threshold such that at least a portion of a moisture content of the mat is in a super-heated liquid state. The method may include maintaining the pressure on the mat above the critical pressure threshold until at least a portion of the plastic fragments of the mat are melted. The method may include decreasing the pressure on the mat below the critical pressure threshold such that the mat expands to a second thickness greater than or equal to a target thickness, and such that the portion of the moisture content of the mat in the super-heated liquid state is converted to steam.

Disclosed herein is an improved cover board product with a panel comprising a top surface layer comprised of paper or a fiberglass web; a bottom surface layer comprised of paper, a fiberglass web, nylon film, polyester film, polypropene film, or textiles; and a core layer comprised of paper and thermoplastic fragments connected by a thermoplastic bonding resin. The thermoplastic bonding resin is in a random pattern to less than 100% of the paper and thermoplastic fragment surface area.

A method for producing a sandwich component, in particular an inner trim component for a motor vehicle, is disclosed. The method begins with a core layer made from a foamed plastic and a cover layer which includes reinforcing fibers and plastic fibers. The plastic of the core layer has a first melting temperature which is higher than the second melting temperature of the plastic fibers of the cover layer. By the core layer being arranged on the cover layer, a multilayer composite is created. This multilayer composite can be further processed into a semi-finished product. The multilayer composite or the semi-finished product is then heated in a heating device to a temperature which is lower than the first melting temperature but therefore higher than the second melting temperature. Then the heated multilayer composite or the semi-finished product is formed in a forming tool in order to produce the sandwich component.

The present invention can be manufactured a recycled leather sheet treated with waterproof and flame retardant in a form of a sheet having a thickness of 10 to 500 mm, and maintains a weight of 700 to 1200 g/m.sup.2 of a final recycled leather weight. In addition, natural fibers, synthetic fibers, and recycled yarns can be plantation treatment on recycled leather by needle punching process to realize the lightweight and flexibility of recycled leather sheet.

A fiber tape for producing fiber reinforced parts is provided. The fiber tape includes a fiber layer and a binder material securing the fibers of the fiber layer to each other. The binder material is provided as a binder mesh covering at least an upper surface and/or a lower surface of the fiber layer.

An automotive trim part is provided made of a laminated structure generally consisting of a thermoplastic core layer extruded from at least one feedstock derived from recycled material. The feedstock may consist at least partially of vehicle trim part waste from another vehicle, or trim part waste associated with an automotive trim part the same or similar to the part being produced. The core layer is preferably covered by fibrous layers and may be configured for use at least as a portion of a vehicle's wheel well.

The present disclosure relates to a method for selecting a polyester film in which the polyester film is used as a sealant layer in a multilayer body including a base material layer including a crystalline polyester film, an adhesive layer and a sealant layer in this order, the method including: a step in which FT-IR analysis is performed on the polyester film by a reflection method, and the crystallinity of the polyester film is measured by the following formula; and a step in which a first polyester film having a crystallinity of 2 to 15% is selected:
I.sub.1409=p1I.sub.1340+p2I.sub.1370(Formula 1)
Crystallinity [%]=p1(I.sub.1340/I.sub.1409)100(Formula 2).

The invention provides a method for delaminating a composite by immersing the composite into a delamination solution; wherein the composite comprises a metal substrate and a coating applied on one side or both sides of the metal substrate, wherein the coating comprises a polymeric binder; and wherein the polymeric binder comprises an aqueous copolymer. The use of delamination solution comprising an alkali metal silicate salt allows for complete delamination of the composite in a highly efficient and extremely fast manner. Furthermore, the delamination method disclosed herein circumvents complex separation processes, contamination and corrosion of the metal substrate and enables an excellent materials recovery. An application of the method for delaminating an electrode for a battery is disclosed herein.
