Assembly comprising a partially breakable fabric and a supporting structure

An assembly comprising:

• a woven first fabric extending in a first overall direction, the woven first fabric comprising first filamentary warp elements, which are substantially parallel to one another and extend in a first warp direction, substantially parallel to the first overall direction, each first filamentary warp element comprising first and second filamentary members;
• a woven or knitted second fabric;
• a bearing structure comprising filamentary bearing elements connecting the woven first fabric and the woven or knitted second fabric together, each filamentary bearing element comprising at least one filamentary bearing portion extending between the woven first fabric and the woven or knitted second fabric,
• wherein the woven first fabric is arranged such that, for an at-rest length L of the woven first fabric in the first overall direction, expressed in m:
• for any elongation of the woven first fabric in the first overall direction less than or equal to (2π×H)/L, the first filamentary member has a non-zero elongation and is not broken, and
• there is an elongation of the woven first fabric in the first overall direction less than or equal to (2π×H)/L, beyond which the second filamentary member is broken,
• in which H0×K≤H where H0 is the mean straight-line distance between an internal face of the woven first fabric and an internal face of the woven or knitted second fabric when each filamentary bearing portion is at rest, H and H0 being expressed in m, and K=0.50.

A tire of revolution about a main axis, the tire comprising:

• a first structure exhibiting symmetry of revolution comprising a woven first fabric comprising first filamentary warp elements, which are substantially parallel to one another and extend in a first warp direction, a circumferential direction of the tire making an angle less than or equal to 10° with the first warp direction, and each first filamentary warp element comprising first and second filamentary members;
• a second structure exhibiting symmetry of revolution comprising a woven or knitted second fabric, the second structure exhibiting symmetry of revolution being arranged radially on the inside of the first structure exhibiting symmetry of revolution;
• a bearing structure comprising filamentary bearing elements connecting the woven first fabric and the woven or knitted second fabric together, each filamentary bearing element comprising at least one filamentary bearing portion extending between the woven first fabric and the woven or knitted second fabric;
• and
• an interior annular space delimited radially by an internal face of the woven first fabric and an internal face of the woven or knitted second fabric,
• wherein H0 is the mean radial height of the interior annular space when each filamentary bearing portion is at rest,
• wherein H is the mean radial height of the interior annular space in the absence of load applied to the tire and in the absence of pressure in the tire such that H0×K≤H where K=0.50,
• wherein the first filamentary member of each first filamentary warp element exhibits, at least over part of its length, a non-zero elongation in the first warp direction and is non-broken, and
• wherein the second filamentary member of each first filamentary warp element is broken at least at one point along its length.

A method for manufacturing a tire comprising:

• winding, about a tire-building drum substantially of revolution about an axis of revolution, an assembly comprising:
• a woven first fabric extending in a first overall direction comprising first filamentary warp elements, which are substantially parallel to one another and extend in a first warp direction, substantially parallel to the first overall direction, each first filamentary warp element comprising first and second filamentary members;
• a woven or knitted second fabric;
• and
• a bearing structure comprising filamentary bearing elements connecting the woven first fabric and the woven or knitted second fabric together, each filamentary bearing element comprising at least one filamentary bearing portion extending between the woven first fabric and the woven or knitted second fabric,
• wherein the winding is performed in such a way that:
• the first warp direction and a circumferential direction of the tire-building drum make an angle less than or equal to 10°, and
• the woven first fabric is moved radially away from the axis of revolution in such a way as:
• to form an interior annular space delimited radially by an internal face of the woven first fabric and an internal face of the woven or knitted second fabric and distant from one another by a mean radial distance H such that H0×K≤H where K=0.50 and H0 is the mean radial height between the internal face of the woven first fabric and the internal face of the woven or knitted second fabric when each filamentary bearing portion is at rest,
• the first filamentary member of each first filamentary warp element becomes elongated in the first warp direction over at least part of its length without breaking, and
• the second filamentary member of each first filamentary warp element breaks at least at one point along its length.
