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.

Method for recycling composite ropes, the method comprising a step of identifying (SO) the type of rope and at least one step of separating components comprising one or the other of the following steps /S1/,/S2/,/S3/,/S4/ as defined below: /S1/—a mechanical separation step, /S2/—a chemical separation step, /S3/—a thermal separation step, /S4/—a biological separation step and machine or installation for recycling composite ropes.

A fiber-reinforced thermoplastic laminate is disclosed that comprises continuous reinforcing fiber. The laminate is custom designed and fabricated to be molded into a specific article of manufacture. Some or all of the continuous reinforcing fiber are severed at precise locations based on the geometric and physical requirements of the article of manufacture to facilitate molding while preserving most of the strength provided by continuous reinforcing fiber.

A composite structural article includes a polymeric body having a first major surface and an opposing second major surface. The composite structure includes a continuous fiber element extending along and embedded within the lateral length of a rib element and/or an open mesh woven element embedded within and coplanar a textured surface of the first major surface or the opposing second major surface.

A system and method for manufacturing a part in a mold having a mold cavity including a printhead for depositing a first material within the mold cavity, and an injection head for depositing a second material within the mold cavity. A part can be made in the mold cavity by the cooperative use of both injection molding and additive manufacturing steps.

An additive manufacturing system is disclosed. The additive manufacturing system may include a moveable support, and a print head connected to the moveable support. The print head may be configured to discharge a continuous reinforcement that is wetted with a liquid matrix. The additive manufacturing system may also include an auto-threader configured to thread the continuous reinforcement through the print head, and a controller in communication with the moveable support, the print head, and the auto-threader. The controller may be configured to selectively activate the auto-threader at a start of a manufacturing process.

The invention concerns a method for the production of a composite profiled section (3) comprising a core (1) and a shell (2), in particular intended for use as a reinforcing element or reinforcing rod in a, preferably thermoplastic, plastic material and/or for use as a reinforcing rod for a spring clip (11), wherein the shell (2) has shell fibres (4) which are laid around the circumference of the core (1), wherein, subsequent to the application of the shell fibres (4) to the core (1), at least one supporting fibre (5) is wound around the shell fibres (4) applied to the core (1) by means of a winding device for the production of a preformed pre-composite profiled section (6). As an alternative and/or in addition thereto, a method for producing an aforementioned composite profiled section (3) is provided, wherein the core (1) is produced continuously by foam extrusion with at least one extruder.

An additive manufacturing system is disclosed. The additive manufacturing system may include a matrix reservoir, a primary nozzle fluidly connected to the matrix reservoir, and a primary cure enhancer operatively connected to at least one of the matrix reservoir and the primary nozzle. The primary cure enhancer may be configured to direct a cure energy toward a tip of the primary nozzle. The additive manufacturing system may also include an auxiliary nozzle, an arm configured to mount the auxiliary nozzle at a trailing side of the primary nozzle, and a passage extending from the matrix reservoir to the auxiliary nozzle.

A continuous reinforcement is disclosed for use in additive manufacturing. The continuous reinforcement may include a plurality of continuous primary fibers oriented in a general axial direction of the continuous reinforcement. The continuous reinforcement may also include a plurality of secondary fibers interspersed with the plurality of continuous primary fibers and oriented generally orthogonal to the plurality of continuous primary fibers.

A compression molding method for creating fine, features having desired fiber-alignment patterns involves creating a pressure gradient in a mold cavity during the soak phase of the compression-molding process. In the illustrative embodiment, the gradient is created by movement of a structure, and results in a flow of nearby fiber and melted resin. This alters local, preexisting, non-random fiber alignments. The process imparts geometries to a part (the bulging features) that are not otherwise present on the mold surface.
