NOVELTY - The utility model claims a composite mica tape with anti-cracking structure, comprising a mica paper, baseband side surface of the mica paper baseband formed with a reinforcing fibre fabric layer; the surface of the other side is formed with an anti-crack reinforcing structure; the anti-cracking reinforcing structure comprises a graphene film layer with a hole, an aromatic polysulphone fibre net surface and an aluminium silicate fibre net surface; the graphene film with hole is formed on the surface of the mica paper base belt; and the surface of the graphene film with hole is formed with an aromatic polysulfonamide fibre net surface and an aluminium silicate fibre net surface through the glue layer sequentially the aromatic polysulphone fibre net surface and aluminium silicate fibre net surface are provided with rhombic meshes, the size of the rhombic grid meshes of the aromatic polysulphone fibre net surface and the aluminium silicate fibre net surface is different, and the aromatic polysulphone fibre net surface and the aluminium silicate fibre net surface are transversely and vertically overlapped on the surface of the glue layer. The utility model makes the mica tape has good anti-cracking performance, which is suitable for strong tension, strong external impact and continuous vibration of using scene.
