Abstract: A method for producing and/or checking a part made of composite materials formed from one fabric having a surface whose texture exhibits a main orientation, including the following steps: obtaining a first image representing the texture of the fabric; determining an estimation relating to the main orientation of the texture, by determining for each pixel of the first image, an orientation of gradients relating to the luminance level of said pixel; determining an estimation of a global distribution of the orientations of gradients of the pixels of the first image; determining the main orientation as a function of the estimation of the global distribution of the orientations of gradients of the pixels of the first image; determining a deviation between the estimation relating to the main orientation and a setpoint value; and producing the part as a function of the deviation and/or emitting a check signal dependent on the deviation.

Abstract: The present invention concerns a method for producing a mould intended for moulding a composite part, in particular intended for the wind power, nautical or aeronautical technical fields. The mould is made from a composite material. Moreover, the heat transfer fluid circuit (2) that said mould comprises is made during the mould production process. The circuit (2) comprises at least one tube made from a material with a low thermal expansion coefficient, advantageously close to that of the composite material.

Abstract: The invention concerns a device (1) for producing a moulded part from a composite material comprising a mixture of reinforcement fibres (2) and a resin (3), said device (1) comprising: a mould (4) wherein a recess (5) is provided, configured for the arrangement of the fibres (2); a counter-mould (6) which is provided with at least one channel (9) for introducing the resin (3) into the recess (5), and which is intended to rest against the mould (4) in order to close the recess (5); means for positioning and securing the counter-mould (6) on the mould (4); at least one means (7) for depressurising the recess (5) the mould (4) and the counter-mould (6) comprising respective support areas surrounding the recess (5), which comprise two seals delimiting a dosing chamber (22). The invention also concerns a method for producing a moulded part from a composite material implementing the device (1).
