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 LR measured in the direction Y of between 2 and 100 mm and has a thickness ER measured in the direction Z of between 0.1 and 5 mm, the LR/ER 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 (Tg1) 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.

    Renfort plat à propriétés mécaniques améliorées, ayant la forme d'un ruban (R1) multicomposite, définissant trois directions principales perpendiculaires, axiale (X), transversale (Y) et radiale (Z), de largeur LR mesurée selon la direction Y comprise entre 2 et 100 mm et d'épaisseur ER mesurée selon la direction Z comprise entre 0,1 et 5 mm, le rapport LR/ER étant supérieur à 3, ce ruban multicomposite comportant au moins: une pluralité de monobrins (10) en matériau composite orientés selon la direction X, comportant des filaments d'une matière minérale (101) noyés dans une résine thermodurcie (102) dont la température de transition vitreuse notée Tg1 est supérieure à 70°C; ces monobrins étant enrobés dans une couche de matière thermoplastique (12). Stratifié multicouches comportant un tel renfort plat multicomposite. Bandage, pneumatique ou non pneumatique, renforcé d'un tel renfort multicomposite ou d'un tel stratifié multicouches.
