摘要:
A method for fabrication of one or more components of an article of footwear is provided. In one example, the method includes fabricating a mixture of polyurethane (PU) precursors and coffee grounds of a first size using a two-step mixing, and then injection molding one or more components of the article of footwear using the mixture, the one or more components of the article of footwear formed of a coffee grounds-PU composite material.
摘要:
A cosmetically altered fiberglass piece having an outer layer of curable gel-coat, an intermediate layer of textile fabric having a graphical element depicted thereon, and an inner layer of composite. A resin or epoxy is used to bond the layers to form the cosmetically altered fiberglass piece. Introduction of resin or epoxy is performed through one of a manual application, a vacuum infusion, or light RTM.
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 composite part defining a button shaped protrusion and including fibers reinforcing a resin matrix throughout the part. The fibers may be in the form of a woven mat or in the form of loose fibers that are deposited in a mold. Methods of making the composite part with a woven mat or loose fibers being provided in the button shaped recess that defines a void in the fiber reinforced composite part at a predetermined location where a self-piercing rivet is to be inserted.

The invention relates to a method for producing a composite component reinforced by stiffening elements.Composite component is produced by the inside gluing of a monolithic component to a multiplicity of stiffening elements by means of an adhesive suitable for this particular application. Stiffening elements are formed with a fiber reinforced, amorphous thermoplastic material. Monolithic component of composite component consists of a fiber reinforced duroplastic material—for example a composite epoxy matrix—in which are embedded, for reinforcement, carbon fibers, basalt fibers, natural fibers, ceramic fibers, Aramide® fibers, Kevlar® fibers or any combination thereof.Monolithic component is glued to thermoplastic stiffening elements by an adhesive under the influence of pressure and temperature. Here a tolerance compensation is carried out essentially by stiffening elements, if necessary being plastically deformed, so that high dimensional stability is achieved. Composite components, which can be subject to high mechanical loads, are therefore provided, in particular, as spare or replacement parts for outer lining parts on aircraft.The invention also relates to a composite component produced by means of a method according to the invention.
摘要:
A method of joining parts together with a flow drill screw or with a clinch joint. A first part formed of metal or a composite material is joined to a second part that includes a fiber-filled layer and a resin matrix layer. The flow drill screw extends through the first part and the second part into the second part. The resin matrix layer prevents fibers from the fiber filled layer from being forced through the back of the second panel. A clinch joint may be formed into the first part and the second part but does not penetrate completely through the resin matrix layer. When the clinch joint is formed, the resin matrix layer inhibits the fiber filled layer from pushing through the second layer of the second panel.
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.

The present invention refers to an adequate composite material to be prepared by an injection process and to an injection process of a composite material. In accordance with the process of the present invention, the composite material is prepared by carrying out the steps of (i) making the length of the natural fibers uniform; (ii) treating the surface of the natural fibers and of the lignocellulosic residues, if present; (iii) premixing the components of the composite; (iv) extruding and granulating the composite material; and (v) injection molding the material of the composite for the conformation of the parts.

摘要:
A method for arranging a thermoplastic insert unit (2) in a thermoplastic sandwich product (1) having at least one planar or virtually planar section by the application of ultrasonic energy (6, 8). A thermoplastic sandwich product (1) comprises at least one fibre-reinforced thermoplastic covering layer (7) and a thermoplastic core which is not completely solid (8). Examples of thermoplastic sandwich products include: a flat plate, a slightly curved product, a folded product, etc. The production of a recess in the surface of the thermoplastic sandwich product, with the plastic insert unit being welded into the recess.
