The present invention relates to a braiding machine with at least two impellers for displacing at least one clapper, wherein the clapper is made at least partially of a ferromagnetic material and wherein each of the impellers has at least one clapper receiver comprising a plurality of electromagnets, wherein the electromagnets enclose a partial circumference of the clapper of about 50° to about 120°.

An apparatus for manipulating a material is provided. The apparatus may comprise a magnetic device arranged in a three-dimensional configuration. The apparatus may comprise a surface on which at least one carrier is configured to move. The magnetic device may be configured to provide a magnetic field for driving the carrier on the surface to manipulate a material. The apparatus may comprise a controller configured to control the magnetic device to modulate the magnetic field. The controller may be further configured to detect a position and/or motion of the carrier.

A braided sleeve with complex geometry, including changes to the geometry along the braided sleeve's longitudinal axis are described. In particular, along a first portion of the braided sleeve's longitudinal axis, multiple tows are intertwined with each other. Along a second portion, one of tows is removed from being intertwined with the other tows and is relocated to an interior or an exterior of the braided sleeve. A third portion includes the removed tow being intertwined with the plurality of tows again. In this manner, the braided sleeve may provide coverage of preforms with varying diameters along the longitudinal axis of the preforms.

Systems and methods are provided for braiding Metal Matrix composite (MMC) tape. One method includes drawing multiple lanes of MMC tape, comprising a matrix of metal reinforced by fibers, from bobbins arranged around a mandrel. The method also includes braiding the multiple lanes to form a preform at the mandrel for an MMC part and consolidating the preform via application of heat and pressure.
