摘要: A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.

摘要: A system for manufacturing a thermoplastic prepreg product includes a belt or conveyor, a prepreg applicator that positions a thermoplastic prepreg atop the belt or conveyor, a foam applicator that applies a foam mixture atop the thermoplastic prepreg, a heating mechanism that heats the thermoplastic prepreg and the foam mixture to cause the foam mixture to react atop the thermoplastic prepreg, and a laminator that is configured to press the thermoplastic prepreg and foam mixture to control a thickness of the resulting thermoplastic prepreg product. The thermoplastic prepreg includes a fabric, mat, or web of fibers and a thermoplastic material that is impregnated within the fabric, mat, or web of fibers. The thermoplastic material is formed from in situ polymerization of monomers and oligomers. The foam mixture includes an isocyanate, a polyol blend, and a blowing agent.

摘要: Disclosed herein a method for making a unidirectional continuous fiber-reinforced resin composite material. A resin plasticized and molten by an extruder is transported to a coating guide roller through a die head, and a hot-melt resin film layer with uniform thickness is formed on a roller surface of the coating guide roller. Simultaneously, the coating guide roller guides the hot-melt resin to continuously and uniformly coat on a row of flattened unidirectional continuous fibers along the roller surface of the coating guide roller. Subsequently, the coated flattened unidirectional continuous fibers pass through an open dip-coating roller device to effectively combine with the hot-melt resin to obtain a composite material of the hot-melt resin and fibers, which passes through a cooling and forming device to a winder under a driving force of a main traction to obtain the unidirectional continuous fiber-reinforced resin composite material.

摘要: A thermoplastic prepreg includes a mat, web, or fabric of fibers and hollow glass microspheres that are positioned atop the mat, web, or fabric of fibers or dispersed therein. The thermoplastic prepreg also includes a thermoplastic polymer that is fully impregnated through the mat, web, or fabric of fibers and the hollow glass microspheres so that the thermoplastic prepreg has a void content of less than 3% by volume of the thermoplastic prepreg. The thermoplastic material is polymerized monomers and oligomers in which greater than 90% by weight of the monomers or oligomers react to form the thermoplastic material.

摘要: A method for producing an insulation material is described herein. The method includes mixing cellulose reinforcement fibers with thermoplastic binder fibers to form a mixture. In addition, the method includes applying heat to the mixture to melt the thermoplastic binder fibers such that the thermoplastic binder fibers bind the cellulose reinforcement fibers together to form a batt. The thermoplastic binder fibers make up about 0.5% to about 25% by weight of the batt. Furthermore, the method includes slicing the batt along a horizontal plane to form a first pad having a first thickness and a second pad having a second thickness. Each of the first and second thicknesses is greater than or equal to about 1/16 of an inch.

The die head includes a body; at least one group of fiber channels arranged in a longitudinal hole-through manner in a middle of the body, and a fiber yarn conveyed in the fiber channel. The body includes a feeding port and discharging ports, which communicate with each other. The discharging ports are located in outer sides of the fiber channel. Thermoplastic base materials in a molten state are paved on two sides of the fiber yarn. The thermoplastic base materials may be paved on surfaces of the two sides of the fiber yarn when being extruded.
