A brake disk () includes an annular core () formed from a plurality of non-annular pieces (), a first friction disk () mounted on a first side of the annular core (), a second friction disk () mounted on a second side of the core () opposite from the first friction disk (), and at least one fastener () connecting the first and second friction disks () to the core (). Also a method of assembling a brake disk from a core and friction elements.

This invention generally pertains to self propagating high temperature synthesis or combustion synthesis as a way of bonding materials. The present invention provides methods and an apparatus for bonding, preferably carbon-carbon composite materials, by combustion synthesis. Generally, the invention involves providing at least two carbon-carbon composite parts to be bonded and interspersing a combustion synthesis material in between the parts with each part in contact with the combustion synthesis material. The combustion synthesis material is then ignited, which initiates the combustion synthesis reaction. Typically, a ceramic material is formed which immediately freezes, bonding the parts together.

A method and apparatus for combining raw fibrous and binding materials in a single mixing step (Step S), followed by consolidation (Step S) so as to greatly shorten the overall cycle time to a finished fiber-reinforced composite part. Chopped fibrous materials and binder materials are deposited sequentially onto a belt conveyor (Step S) so that the materials are successively layered, one on top of each other in a predetermined ratio, and subsequently mixed (Step S) to achieve uniform dispersion throughout. The mixed materials are then deposited into a rotating mold (Step S) to further ensure uniform dispersion of fibrous and binder materials. Impregnation of the fibrous materials with the binder material occur in-situ as the uniformly mixed materials are heated and subsequently compacted in the mold (Step S) to obtain the desired shape of the fiber-reinforced composite part.

Molding apparatus for rapid transfer of molten resin or pitch in an infiltration molding process. The apparatus includes e.g. an extruder () for melting and conveying a resin or pitch and a mold () arranged so that resin or pitch is conveyed to a mold insert cavity () within the mold. The mold insert contains an internal protrusion such as a locating ring () for positioning a porous body () within the mold insert cavity in a position that brings about unidirectional flow of the molten resin or pitch through the porous body. Also, rapid resin or pitch infiltration molding process that includes injecting a high melting point, high viscosity, molten resin or pitch into the mold to effect a unidirectional impregnation of a heated preform via a pressure gradient in the mold.

Fiber reinforced composite parts

A resin transfer molding (RTM) process is disclosed for rapidly filling a fibrous preform and/or a rigid, porous body with high viscosity resin or pitch. The process is suitable for impregnated multiple porous bodies stacked in a single mold. The process uses a fibrous preform or rigid porous body which is placed into a mold matching the desired part geometry. A resin is injected into the mold at temperature and pressure. After cooling, the infiltrated component is removed from the mold. The mold is constructed from two halves fitted to form at least one mold cavity. A gate fitted with a nozzle is set into one of the mold halves, and a valve admits resin or pitch into the gate area. Venting or vacuum can be applied to the mold. The mold is held in a hydraulic press and an extruder, optionally fitted with an accumulator, supplies molten resin or pitch to the mold.

A method and apparatus for combining raw fibrous and binding materials in a single mixing step (Step S ), followed by consolidation (Step S ) so as to greatly shorten the overall cycle time to a finished fiber-reinforced composite part. Chopped fibrous materials and binder materials are deposited sequentially onto a belt conveyor (Step S ) so that the materials are successively layered, one on top of each other in a predetermined ratio, and subsequently mixed (Step S ) to achieve uniform dispersion throughout.
