Abstract: A method for impregnating an oxide fibre roving with a matrix of alumina and silica includes a introducing an oxide fibre roving into an impregnation bath, wherein the impregnation bath is prepared by sol-gel process and includes a silica precursor in the form of a hybrid polymeric sol, an alumina precursor in the form of a colloidal sol and ceramic particles.

Abstract: A method of fabricating a composite part, includes forming a fiber preform for the part that is to be obtained by depositing a plurality of fiber structures impregnated with a thermoplastic polymer onto a surface, with deposition being performed by automated fiber placement; eliminating the thermoplastic polymer present in the preform by dissolution with a solvent; and injecting a liquid impregnation composition into the pores of the fiber preform after eliminating the thermoplastic polymer in order to form a matrix in the pores of the fiber preform.

Abstract: An installation for depositing a shaped filled roving intended to be used to manufacture a composite-material component, includes a device for feeding a fibrous roving impregnated with a composition including a binder and ceramic or carbon fillers, a die for shaping and draining the binder defined by at least one porous surface, the die having an evolving section between an inlet section and an outlet section, the inlet section being larger than the outlet section, a support in communication with the die outlet on which the shaped roving is to be deposited, and a first conveying device configured to convey the roving from the feed device through the die and to the support.

Abstract: A planetary transmission, comprising a housing, a drive part, an output part having an output shaft that is rotatable about an output axis of rotation, and at least one gear stage between the drive part and the output part. The drive part, the at least one gear stage, and the output part are mounted in the housing, the housing has an output flange on the output side, wherein the output flange has a first lateral surface with circularly symmetrical in radial planes about an axis of symmetry, wherein the first lateral surface is arranged eccentrically with respect to the output axis of rotation.

Abstract: The invention relates to a planetary transmission (100), comprising a housing (110), a drive part, an output part having an output shaft that is rotatable about an output axis of rotation, and at least one gear stage between the drive part and the output part. The drive part, the at least one gear stage, and the output part are mounted in the housing (110). On the output side, the housing (110) has an output flange (140), wherein the output flange has a first lateral face (115), which in radial planes is circularly symmetrical about an axis of symmetry. The first lateral face (115) is arranged eccentrically with respect to the output axis of rotation. Due to the eccentricity of the lateral face (115) with respect to the output axis of rotation, a component mounted on the output part, for example, a pinion (20) or a belt pulley, can be adjusted by twice the value of the eccentric by way of a rotation of the planetary transmission (100).
