Friction lining
Runge et al of Schaeffler Technologies AG & Co. KG, Germany,  developed a friction lining, which has a friction part and a backing part. As a preform, wound from a strand material and treated with a binder, the friction part is subjected to hot pressing.  The backing part is subjected to hot pressing together with the preform, so that a bond is created between the friction part and the backing part by the polymerization of the binder.

Wet friction lining
Foge of Miba Frictec GmbH, Austria, produced a friction lining by curing a textile fabric of staple fibers (30 to 200 mm long) with a resin under pressure or at an increased temperature.  The resin or resin mixture is cured in at least two steps.  In a first step the resin or resin mixture is pre-polymerized to produce a pre-product and final curing of the resin or resin mixture takes place in another step once the pre-product has been placed on a substrate.  The pre-polymerization of the resin or resin mixture is run without pressure.  (RDC 12/6/2012)

Method of making a fiber preform for manufacturing parts of a composite material of the carbon/carbon type incorporating ceramic particles, and products obtained thereby
Baud and Giraud of Messier-Bugatti, France, impregnated one or more two-dimensional fiber fabrics of carbon or carbon precursor fibers by a solution or a suspension capable of allowing a dispersion of discrete ceramic particles to remain in the fiber fabric, and a fiber preform is made by superposing plies formed of two-dimensional fabric made of carbon or carbon precursor fibers, the plies being bonded to one another, and at least some of the plies being at least partially formed of a previously-impregnated two-dimensional fabric. The field of application is particularly that of friction parts made of C/C composite material with incorporated ceramic particles. (RDC 10/11/2012)
