METHOD FOR PRODUCING A MATERIAL WEB, USE THEREOF AS A REINFORCING PLY FOR AN ELASTOMER ITEM, AND VEHICLE PNEUMATIC TIRES

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.

Hybrid metal and composite polymer wheels for motor vehicles

Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.

METHOD AND APPARATUS FOR CURING A COMPOSITE ARTICLE

Disclosed is a method of curing a composite article and associated curing apparatus. A heat source is provided for heating the composite article. A temperature related property is detected proximal to the heat source and the heat output is regulated to a predetermined temperature vs. time profile. Heat output vs time data is acquired and functionalised and the curing completion time is determined based on the functionalised heat output vs time data. The method provides for heating a composite article so as to follow a predetermined temperature vs. time profile (i.e. a cure profile) and avoid excessively high temperatures. The required heat output vs time has also been found to be broadly reproducible, and the curing completion time can be more readily determined from functionalised heat output vs time data, for example by identifying reproducible characteristics of the functionalised data.
