COSMETICALLY ALTERED FIBERGLASS PIECE

A cosmetically altered fiberglass piece having an outer layer of curable translucent coat, an intermediate layer of textile fabric having a graphical element depicted thereon, and an inner layer of fiberglass 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.

Article assembly disassembly system

There is described a system, article, method, connectors and apparatus for article reuse or recycling, which system including the assembling of an article from at least two components at least one of which has a textile material brought into communication with each other through one or more connectors and the subsequent disassembling of the article and use of one or more of the components in the assembling stage. The assembled article is susceptible to automatic or semi-automatic disassembly through one or more of its connectors being susceptible to a reduction in one or more mechanical properties under exposure of the article to electromagnetic energy especially microwave. The article may be a garment that has joins stitched with a microwave susceptible yarn. The yarn is ideally manufactured from pseudo-conductive materials and is metal free.

20240307212 · 2024-09-19 ·

A method of forming an ostomy pouch comprising: providing a film to form a first cavity wall and a second cavity wall; providing a comfort material to form a comfort layer; wherein the comfort material is a woven fabric material with a hot melt adhesive coating thereon; joining the first cavity wall to the second cavity wall at a first temperature and a first pressure for a first time period; and subsequently joining a comfort layer to at least one of the first and second cavity walls at a second temperature and a second pressure for a second time period.

Multi ply thermoplastic conveyor belt

Methods include providing a plurality fabric material layers, applying a plastisol layer between each fabric material layer forming plurality fabric material layers thereby creating a belt carcass, pressing the fabric material layers together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while heating the preformed fabric carcass while heating the preformed fabric carcass to a temperature which is within the range of about 360 F. to about 450 F. for a period of at least 6 minutes, disposing a thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, pressing the thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, and splicing opposing distal ends of the belt in a stepped splice configuration. The layers may be devoid of covering strips of lattice fabric disposed adjacent an abutment of any proximally positioned fabric layer.

Process for the treatment of technical textiles
09873212 · 2018-01-23 · ·

The present invention relates to a process for the treatment of technical textiles based on thermoplastic fibers and comprising a coating, such as, in particular, airbags, using the principle of centrifugal decanting to separate the fiber residues and the coating material. The invention also relates to a process for the manufacture of a thermoplastic composition, in particular for molding, obtained by use of the fiber residues as obtained and optionally of reinforcing fillers. The distinguishing feature of this invention is based on the preparation of the fabric devoid of coating, thus resulting in formulations with elevated mechanical performances.

Method for cosmetically altering a fiberglass piece

A method of cosmetically altering a fiberglass piece comprising having a graphical element disposed on a layer of textile fabric. An outer layer of a curable gel-coat is applied to a mold for the cosmetically altered fiberglass piece. At least one intermediate layer of textile is then applied over the outer layer, the textile comprising a graphical element disposed adjacent to the outer layer. An inner layer is then applied to the intermediate layer, the inner layer providing structural support to the fiberglass piece. A bonding agent is then applied to wet out the outer layer, the intermediate layer, and the inner layer, thereby resulting in an assembly of a wet out three-layer combination, the curing of which results in the cosmetically altered fiberglass piece.

FIBER-REINFORCED RESIN MOLDED BODY AND METHOD FOR PRODUCING SAME

Provided is a fiber-reinforced resin molded body that has continuous voids and includes a carbon fiber nonwoven fabric and a thermosetting resin, in which the continuous voids have a porosity of 50% by volume to 97% by volume, and contact points of discontinuous carbon fibers constituting the carbon fiber nonwoven fabric are immobilized by the thermosetting resin having a substantially spherical shape of 40 m to 300 m in diameter. Also provided is a method of producing a fiber-reinforced resin molded body, the method including the following steps in the order mentioned: the preform forming step of forming a preform including a carbon fiber nonwoven fabric in a molding die; the injection preparation step of forming a closed space in which the preform is arranged; the injection step of injecting a liquid thermosetting resin into the closed space; the porosity adjustment step of allowing the carbon fiber nonwoven fabric to expand in the thickness direction; and the curing step of maintaining the preform at a temperature equal to or higher than a curing temperature of the thermosetting resin. According to this method, a fiber-reinforced resin molded body that includes a carbon fiber nonwoven fabric and a thermosetting resin is simply produced.
