| abstract |
The present invention relates to a planar reinforcement with improved mechanical properties which has the shape of a multi-composite band (R1), wherein said reinforcement defines three main perpendicular directions, the axial direction (X), the transverse direction (Y) and the radial direction (Z), has a width L R measured in the direction Y of between 2 and 100 mm and has a thickness E R measured in the direction Z of between 0.1 and 5 mm, the L R /E R ratio being greater than 3. Said multi-composite band comprises at least a plurality of monofilaments (10) which are made of composite material and are oriented in the direction X, comprising filaments made of an inorganic material (101) which are embedded in a thermoset resin (102), the glass transition temperature (Tg 1 ) of which is greater than 70 °C. Said monofilaments are coated in a layer of thermoplastic material (12). The invention also relates to a multi-layered laminate comprising such a multi-composite planar reinforcement. The invention further relates to a pneumatic or non-pneumatic tyre, which is reinforced with such a multi-composite reinforcement or such a multi-layered laminate. |
