Problems solved by technology

[0015] Even though these flexible laminates and wheels have demonstrated high effectiveness, they have shown the disadvantage of being relatively complex to manufacture and therefore of high cost price, so much so that it is desirable to find cheaper and at least as effective, especially for the above mentioned Effective replacement for a wide range of service temperatures

Embodiment Construction

[0030] 4. Definition

[0031] In this patent application, unless expressly stated otherwise, all percentages (%) shown are percentages by weight.

[0032] The expression "x and / or y" means "x" or "y" or both (ie "x and y"). Any numerical interval denoted by the expression "between a and b" represents a numerical range extending from greater than a to less than b (i.e. excluding the endpoints a and b), while any numerical range denoted by the expression "a to b" A range of values ​​extending from a to b (ie including the strict endpoints a and b) is intended.

[0033] Furthermore, in this patent application:

[0034] - "composite" when referring to any material or object is understood to mean a material or object comprising short or continuous fibers encased in a resin matrix;

[0035] - "layer" is understood to mean a sheet or any other element of relatively small thickness compared to other dimensions, which layer may or may not be homogeneous or cohesive in nature, havi...

Abstract

A non-pneumatic resilient wheel (30), defining three perpendicular directions, circumferential (X), axial (Y) and radial (Z), comprising at least: a hub (31), an annular band referred to as a shear band (32) oriented in the circumferential direction (X), surmounted by a tread (33) and a plurality of support elements (34) connecting the hub (31) to the annular band referred to as a shear band (32),the annular band referred to as a shear band (32) consisting of a laminate comprising at least one layer of silicone rubber sandwiched between two fiber / resin composite layers comprising filaments ofa mineral material embedded in a thermoset resin.

Description

technical field [0001] 1. Field of the invention [0002] The present invention relates to laminated products, that is to say products made of several layers joined together having a planar or non-planar shape. [0003] The present invention relates more particularly to elastic (flexible) tires or wheels for motor vehicles of the "non-pneumatic" type, that is to say not requiring an inflation gas (such as air) to assume their usable shape; and also It concerns the introduction of a laminated product in such a wheel in the form of a composite material consisting at least partly of fibers wrapped in a resin matrix. Background technique [0004] 2. Background technology [0005] Elastic or flexible non-pneumatic wheels or tires, ie tires or wheels capable of deforming under a given stress and returning to their original shape once released from that stress, are well known to those skilled in the art. They have been described in many patent documents, for example in patent...
