Disclosed herein a method and equipment 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 the main traction to obtain the unidirectional continuous fiber-reinforced resin composite material.

The invention is directed to a vehicle pneumatic tire wherein strengthening plies are provided with steel cords running parallel to one another. The belt plies can be used, as isolated electrically conductive plates, for supplying electricity to electrical consumers such as sensors and actuators installed in the tire. Adjacent belt plies can be connected by puncture sensors to be able to identify damage to the belt caused by metallic parts penetrating from the outside, such as nails, on the basis of a change in the electrical resistance.

The present invention relates to a method for producing a fiber-plastics-composite tool component (1) having a matrix system (6) that has embedded fibers, PBO fibers (4) being selected as the fiber component and a thermosetting plastics matrix (8) being used as the matrix component of the matrix system (6) (S1), which thermosetting plastics matrix has such adhesion to the PBO fibers (4) in the hardened fiber-plastics composite (2) that the coefficient of thermal expansion of the PBO fibers (4) is imparted to the matrix system (6).

An FRP continuous molding apparatus continuously molds an FRP from a layered sheet that includes prepreg sheets layered over each other. The prepreg sheets each include thermoplastic resin and reinforcement fibers, and differ from each other in fiber orientation. The FRP continuous molding apparatus includes: sheet feeding devices continuously feeding the layered sheets in a feeding direction; a layering device layering, over each other, the layered sheets fed from the sheet feeding devices, and thereby forming a sheet layered body; and a shaping mechanism molding the sheet layered body into an FRP while the sheet layered body is being transferred in the feeding direction. The FRP has a cross section that is a target shape. The sheet layered body includes the reinforcement fibers whose fiber orientation is the feeding direction.

A system and method for fabricating large composite fuselages or other vehicle structures, in which the composite structure is fabricated and cured as on a tool, segmented and removed from the tool without disassembling the tool, and then reassembled off the tool to reform the large structure. The tool includes mandrel segments attached to a substructure. The attachments may be moveable to accommodate differential expansion and contraction during curing, and the tool may be rotatable to facilitate access. A composite material of resin and synthetic fibers is applied over the mandrel segments to fabricate the structure on the tool. Caul plates are secured over the composite material, and the composite material is cured on the tool. The resulting structure is cut into part segments which are then removed from the tool, and the part segments are joined to reassemble the large composite structure off the tool.

A fiber composite laying method for producing a fiber composite scrim for forming a fiber composite component. The method includes supplying a reinforcement fiber band to a laying head, laying and compacting the supplied reinforcement fiber band on a laying surface at an average compaction pressure by a compaction roller, and detecting a local compaction pressure on the laid reinforcement fiber band by pressure sensors on the compaction roller.

A pressurizing pre-impregnating die head for a fiber reinforced plastic sheet machine is provided. 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.

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.
