Crown reinforcement for an aircraft tire
Crown reinforcement of an aircraft tire comprises a working reinforcement (2) radially inside of tread (3) and radially outside of carcass reinforcement (4). Working reinforcement (2) comprises two working bi-plies (21, 22) radially superposed with respective axial widths (L.sub.1, L.sub.2), from first axial end (I.sub.1, I.sub.2) to second axial end (I.sub.1, I.sub.2). Each working bi-ply (21, 22) comprises two working layers (211, 212; 221, 222) radially superposed and respectively made up of axially juxtaposed portions of strip (5) of axial width W extending circumferentially in periodic curve (6) that forms, in the equatorial plane (XZ) of the tire and with the circumferential direction (XX) of the tire, a non-zero angle A and has a radius of curvature R at its extrema (7). The difference DL between the respective axial widths (L.sub.1, L.sub.2) of the radially superposed working bi-plies (21, 22) is at least equal to 2(W+(RW/2)(1cos A)).
Composite material vane with integrated aerodynamic covering element and manufacturing method thereof
A method of manufacturing a composite material vane with a covering element, the vane including a platform and a profile extending perpendicularly to the platform, comprises the following steps: providing a covering element and a preform of the vane, the preform comprising a platform portion and a profile portion extending substantially perpendicularly to the platform portion; positioning the covering element against the platform portion so as to obtain an assembly; placing said assembly in a mold; injecting a first resin into the mold so that said resin impregnates and covers the preform and covers at least a portion of the covering element; and carrying out a heat treatment so as to harden the first resin.
Endless flat belt and method for manufacturing the same
An endless flat belt includes an inner rubber layer 1, a cord core 11 buried in the inner rubber layer 1 and spirally wound at a predetermined pitch in a width direction of the belt, and a reinforcement fabric 2 stuck to the inner rubber layer 1. The cord core comprises polyamide fiber. Opposite ends of the reinforcement fabric 2 are connected with each other into an endless form by adhesion or sewing. A surface rubber layer 3 is stuck to a surface of the reinforcement fabric 2 which is opposite a surface thereof stuck to the inner rubber layer 1.
VEHICLE SEAT TRIM COVERS INCLUDING INTEGRALLY-KNIT BACKING MATERIALS AND METHODS OF MANUFACTURING VEHICLE SEAT TRIM COVERS
A trim component for attachment to a vehicle seat includes a first portion and a second portion. The first portion is disposed on a first side of the trim component and defines a first knit. The second portion is disposed on a second side of the trim component and defines a second knit distinct from the first knit. The first and second portions are integrally knitted. The trim component is configured to be installed on or more support members of the seat. The first side is configured to face the support member. The second portion is configured communicate with an occupant of the seat. In various aspects, the first portion includes a first yarn and the second portion includes a second yarn that is distinct from the first yarn with respect to one or more of density, thickness, and material. In various aspects, the first yarn is a heat-activated yarn.
BONDED COMPOSITE OF THERMOPLASTIC-RESIN-BASED FIBER-REINFORCED COMPOSITE MATERIAL AND METAL MEMBER, AND METHOD FOR PRODUCING BONDED COMPOSITE
