FIELD: textile, paper.
SUBSTANCE: three-layer metal cord with the structure L+M+N comprises an inner layer of L wires with d1 diametre. L amounts to from 1 to 4. The inner layer is enclosed by an intermediate layer of M wires with d2 diametre which are jointly wound in a spiral with a pitch p2. M amounts to from 3 to 12. The intermediate layer is enclosed by an outer layer of N wires with d3 diametre which are jointly wound in a spiral with a pitch p3. N amounts to from 8 to 20. A shell which is formed from a structured or cross-linked rubber composition based on at least one diene elastomer covers at least one intermediate layer. The invention relates also to a composite fabric that is used as a reinforcement layer in heavy load tyre carcass. The composite fabric contains a rubber matrix reinforced by the multilayer cord. A tyre reinforced by such cord or comprising such composite fabric is proposed as well.
EFFECT: reinforcement of products made from rubber and plastic.
