摘要:
A vehicle interior material that is manufactured at by bonding a base member and a surface member with each other without using an adhesive agent or an adhesive film, that is light in weight and that has adhesive strength and abrasion resistance. The base member includes a natural fiber or a glass fiber and a first thermoplastic resin fiber and has a density of 0.2 to 0.7 g/cm3 The surface member includes a second thermoplastic resin fiber and a low melting point resin fiber and that has a weight per unit area of 50 to 500 g/m2. The surface member is laid on a surface of the base member. An entangled layer where the second thermoplastic resin fiber enters texture of the base member to be entangled with the first thermoplastic resin fiber is provided at an interface between the base member and the surface member.

A polymer composite and its method of manufacture using a recycled multilayer material. An example of the recycled multilayer material is comprised of a polyethylene/polyethylene terephthalate/aluminum film or polyethylene/nylon/aluminum film that may be extruded with organic filler to obtain desirable performance in wood-substitute products such as deck boards, railing, fencing, pergolas, residential cladding/siding, sheet products, and other applications.

A load carrier is at least partially made of a nonwoven composite material board. The nonwoven composite material board comprising: includes unraveled natural fibers and/or glass fibers, and plastic fibers. Also disclosed is a process for manufacturing a load carrier. The process includes mixing unraveled natural fibers and/or glass fibers, and plastic fibers, and thermoforming the mix into a nonwoven composite material layer. The disclosed load carriers may be any type of load carriers, such as boxes, top decks, cases, crates, and the like, and in particular, pallets.
摘要:
A method of producing a composite material, comprising an assembly of natural fibers, impregnated with an amorphous or semi-crystalline thermoplastic polymer, said method including: i) a step of impregnating said assembly with a precursor composition in the molten state and including: a) at least one prepolymer P(X)n of said thermoplastic polymer, having a molecular chain P having, at the ends of same, n reactive functions X, with n ranging from 1 to 3, in particular n being 1 or 2, and preferably 2 b) at least one chain extender Y-A-Y including reactive functions Y with at least one of said functions X ii) a step of polymerization by mass (poly)addition, in the molten state, of said prepolymer with said chain extender with: said thermoplastic polymer being the result of said polymerization by mass polyaddition and said impregnation i) and polymerization ii) taking place at a temperature lower than 250° C.
摘要:
A plain stepped splice lay-out scheme is presented that can be used for splicing strips to one another that comprise longitudinally arranged cords. The strips can take the form of a conveyor belt, transmission belt, timing belt, elevator belt, a rubber track or a reinforcing strip. The splice is optimised for uniform bending stiffness and maximum strength retention. The cross section of the strip and the splice are substantially equal: there is no increase in thickness or width at the splice. The splice lay-out is characterised by the fact that the abutments (130)—those positions where cord ends (111, 121) meet—are positioned sufficiently far away from one another and by preference as far away from one another as possible. Preferred embodiments in terms of length common between cords of the different strips and local strength are given.
摘要:
A method of joining parts together with a self-piercing rivet that is inserted through a part and partially through a second part. The second part includes a fiber-filled layer and a resin matrix layer that together form a composite part. A self-piercing rivet extends into the second part, but does not penetrate completely through the matrix layer. An assembly, including a first part and a second part that includes a reinforced layer and a resin layer in which a fastener is inserted, but does not extend through the second layer. A composite part including a first layer of resin matrix reinforces the filler and a second layer of resin matrix that does not include a filler and is more than 3 microns thick.
摘要:
There are provided a vehicle interior finishing laminate sheet in which a polypropylene resin foam board of high foaming extent having interconnected cells is used as a core member, a vehicle interior trim material, a method for manufacturing the vehicle interior finishing laminate sheet, and an apparatus therefor. The present invention relates to a vehicle interior finishing laminate sheet 1 provided with a core member consisting of a polypropylene resin foam board 2. The polypropylene resin foam board 2 is extrusion molded into a plate shape, and has an interconnected cell ratio of 50% or higher and a foaming extent of 10- to 50-fold. A plurality of polypropylene resin foam boards 2, 2 are joined to each other by the hot plate welding method or the laser transmission welding method, whereby a large-size core member of vehicle interior finishing laminate sheet 1, which is used for a roof lining or the like, can be formed.

There are provided screw segments 100, 200 that are capable of shearing and kneading feedstock without causing plugs within a cylinder 1 of a screw extruder, and of extruding it from the cylinder 1. The screw segments 100, 200 each comprise a shaft part 111 to be affixed to a screw shaft 7, and a tooth part 112 that protrudes radially outward from the shaft part 111. The tooth part 112 comprises a tooth surface 116 that is formed on the front side relative to the rotation direction of the screw shaft 7, and that is so sloped as to transition gradually forward relative to the rotation direction as it transitions radially outward from the shaft part 111.
摘要:
Textile compositions comprising at least one filamentous fungus are disclosed, as are methods for making and using such textile compositions. Embodiments of the textile compositions generally include at least one of a plasticizer, a polymer, and a crosslinker, in addition to the filamentous fungus. The disclosed textile compositions are particularly useful as analogs or substitutes for conventional textile compositions, including but not limited to leather.
摘要:
A method for the connection of moulded parts, wherein a locking collar pin with locking grooves or with an external thread, is driven through the moulded parts and subsequently a locking collar is locked together with at least some of the locking grooves, or with threaded sections of the locking collar pin, by the application of radial pressure, or by means of a screwing operation. A connecting system with a locking ring pin, which has a punching section for purposes of punching through the moulded parts, and also locking grooves for purposes of active engagement with a locking ring; the latter extends over at least two adjacent locking grooves in the axial direction, or over at least two adjacent threads in the axial direction.
