US Patent 10259266 Multi-composite planar reinforcement

A flat or planar reinforcer shaped as a multicomposite strip (R1), which is defined by three main perpendicular directions: an axial direction (X), a transverse direction (Y), and a radial direction (Z), has a width LR in the Y direction of between 2 and 100 mm, and has a thickness ER in the Z direction of between 0.1 and 5 mm. A ratio LR/ER is greater than 3. The multicomposite strip includes a plurality of monofilaments made of a composite material. The monofilaments are oriented along the X direction and include filaments of a mineral material embedded in a thermoset resin having a glass transition temperature Tg1 that is greater than 70° C. The monofilaments are coated in a layer of thermoplastic material. The reinforcer may be used to reinforce a tire and a multilayer laminate, which may be used to reinforce a tire.
