FIBER-REINFORCEMENT OF FOAM MATERIALS
The present invention relates to a molding made of foam, wherein at least one fiber (F) is located partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fiber (F) not surrounded by the foam thus each project from one side of the molding. The foam is produced by polymerization of a reactive mixture (rM) comprising at least one compound having isocyanate-reactive groups, at least one blowing agent and at least one polyisocyanate.
Methods of forming composite structures
A method of forming a composite structure including coupling a plurality of components together forming a joint: wherein the plurality of components are oriented to form a radius gap therebetween: forming a filler structure that includes a closed cell foam core that has a porosity within a range defined between about 20 percent and about 40 percent by volume of the closed cell foam core and wherein the closed cell foam core is formed from a silicone-based material. The method also includes positioning the filler structure in the radius gap: and applying at least one of heat or pressure to the plurality of components and the filler structure.
FOAMED SOLE COMPONENTS AND METHOD FOR MAKING A SOLE WITH FOAMED SOLE COMPONENTS
A sole structure for articles of footwear and a method of manufacturing them comprising at least one polymeric foamed component expanded through supercritical fluid (SCF) expansion of a shaped pre-expanded polymeric material. The polymeric foamed component may include apertures situated and fashioned in the formation of the pre-expanded polymeric material to promote uniform expansion and optimal curing conditions during the SCF expansion process. At least one polymeric foamed component having one set of physical properties that may be bound to or assembled in conjunction with one or more sole components having the same or another set of physical properties.
Method and foam die for manufacturing seat cushion material
A method for manufacturing a seat cushion material, the seat cushion material including a front layer part and a back layer part having a back side surface, the method including: preparing for molding the seat cushion by attaching the back layer part to an upper die having an upper cavity surface; molding the seat cushion material by adding foamed resin raw material forming on a lower cavity surface of a lower die and then by closing the upper die to which the back layer part is attached, the lower cavity surface being provided with a plurality of protrusions which is configured to be brought into contact with a seating surface side of the back layer part and press the back layer part against the upper cavity surface when the upper die to which the back layer part is attached is closed; and demolding the molded seat cushion material.
Fiber-reinforcement of blowing-agent containing foam materials
The present invention relates to a process for producing a molding made from blowing agent-containing foam comprising at least one fiber (F), wherein the at least one fiber (F) is partially introduced into the blowing agent-containing foam. The two ends of the respective fiber (F) that are not surrounded by the blowing agent-containing foam thus project from one side of the corresponding molding. The present invention also provides the molding as such. The present invention further provides a panel comprising at least one such molding, produced by the process according to the invention, and at least one further layer (S1). The present invention also provides for the production of the panels of the invention and for the use thereof, for example as a rotor blade in wind turbines.
Method And A System For Producing A Component Or Semifinished Product With A Fibre-Reinforced Foam Core
A system for producing a component or semifinished product with a fibre-reinforced foam core, includes a substrate on which the foam core having a first main surface and an opposite second main surface is to be laid; a sewing device having a needle configured to be moved at least linearly; a fibre supply device for three-dimensional supply of a fibre; and a coating device. The sewing device is configured to position the needle at the first main surface and to pierce the foam core, such that a needle tip penetrates through the first main surface and then through the second main surface. The fibre supply device is configured to position a reinforcing fibre such that the reinforcing fibre is hooked into the needle tip. The coating device is configured to coat a reinforcing fibre hooked into the needle tip with resin immediately before the reinforcing fibre enters the foam core.
Process for Flexibly Manufacturing Wetsuit or Garment by Integrally Forming a Functional Surface Layer on a Rubber Foam Subtrate
A process for flexibly making a wetsuit or the like is disclosed by integrally forming a functional surface layer on a rubber foam substrate sheet, thereby rendering the function of the surface layer for the wetsuit or the like.
Method for producing a self-adhesive
A method for producing a foamed thermally crosslinked mass system, wherein the mass system is foamed at a first temperature in a first step, and crosslinker substances are added to the mass system in a subsequent step at a second temperature lower than the first temperature, wherein the crosslinker substances are crosslinker substances for thermal crosslinking of the mass system.
Forming of motor vehicle seat upholstery
The invention concerns a mold for forming an element for covering a lining of a seat member for a motor vehicle, comprising: a matrix (62) provided with ribs (624) for defining style extension lines (36); and a punch (64) provided with ribs (642), to either side of a line of the ribs (624) of the matrix (62).
FIBER-REINFORCED FOAM MATERIAL
The present invention relates to a process for producing a fiber-foam composite (FSV1), wherein a first fiber material (FM1) is applied to a first foam body (SK1) to give a first structured fiber surface (FO1) to which a second foam body (SK2) is subsequently applied to give the fiber-foam composite (FSV1).
