Abstract: A porous, woven carbon fabric friction material is bonded to a solid substrate, such as a conical transmission synchronizer, with a high temperature thermosetting adhesive, such as a synthetic rubber-phenolic resin base adhesive. Prior to applying the adhesive, a thin layer of one surface of the friction material is removed, such as by contacting the surface with a band-type sander, to break through the pyrolytic carbon coating on the substantial portion of the carbon fibers. The adhesive is applied to the abraded surface of the friction material and/or a roughened surface on the solid substrate, the friction material is clamped to the solid substrate and the thus-assembled parts are heated to at least substantially cure the adhesive. Improved bonds between the adhesive and friction material are produced and a tendency for the adhesive to "bleed through" the pores of the friction material and migrate to the friction surface during curing is significantly reduced.

Abstract: A carbonizable body is formed by infusing a plurality of preoxidized, preferably stabilized by known processing to have about 17 to 30 weight percent oxygen, fibers prepared from pitch, in a non-polar liquid plasticizer, typically quinoline, capable of extracting a tarry leachate from the fibers. The infusion of the fibers in the plasticizer is continued for a sufficient time for a substantial amount of leachate to form on the surface of the fibers. The treated fibers are then consolidated or diffusion-bonded to one another or other fibers, as by orienting the treated fibers in a mold and subjecting them to isostatic pressing at relatively low temperatures and pressure. Further processing of the consolidated fibers with appropriate heat treatment in an inert atmosphere will produce a carbonized bulk product with higher values of Young's modulus for the carbonized material than have been previously achieved at such carbonization temperatures.

Further processing of the consolidated fibers with appropriate heat treatment in an inert atmosphere will produce a carbonized bulk product with higher values of Young's modulus for the carbonized material than have been previously achieved at such carbonization temperatures.

Abstract: A method and apparatus for bending flat thermoplastic laminates into structural shapes such as angles, channels, Z sections, J sections and I sections. In order to bend the laminate into the desired shape by appropriate tooling, heat is applied in a localized manner only to the area that is to be bent. The application of heat is sufficient to heat the laminate to its softening temperature in the bend area, and the plies of the laminate can thus slip in the bend area only as bending force is applied so that the bend can be made without the need to heat the entire laminate to the softening temperature.

Abstract: An apparatus and a method for hot-forming a laminated sheet of synthetic resin. The sheet, in at least its region that is to be deformed, is heated to the forming temperature which is equal to or higher than the melting temperature of a thermoplastic bonding agent which is disposed between the laminate layers containing a duromer plastic material and planar carrier materials. The sheet is bent around a cylindrical surface with the aid of a movably guided bending plate, and is cooled. During a large part of the bending operation, the bending plate will be in planar contact with the border region of the sheet. The individual laminate layers will be mutually displaced in the bending region and in the border region in the direction of the sheet's surface, and after the bending operation, the bending plate holds the border region in its bent position at least until the resolidification of the thermoplastic bonding agent.

Abstract: A method of producing a continuous fiber reinforced bent resin pipe, including winding a continuous reinforcing fiber on the outer surface of a tube-like flexible core mold while such core mold is straight in shape, the flexible core mold which is straight when unloaded being capable of keeping a cross section defined in radial direction when the core mold is bent. The core mold on which the continuous fiber has been wound is then bent and placed into a cavity defined by an outer mold formed of split molds each having an inner surface forming the predetermined outer configuration of a bent pipe. A liquefied synthetic resin is caused to be cured between the outer and the core molds to integrate both the fiber and resin. Thereafter the molded product is removed from the outer mold and the core mold is removed from the molded product.

Abstract: A neutron-absorbing material is formed by a process which includes the steps of: mixing an absorptive material having a high thermal neutron capture cross-section (e.g., B.sub.4 C), a neutron-moderating material (e.g., graphite) and a binder (e.g., a phenol formaldehyde resin); shaping such mixture; curing such shaped mixture (e.g., to complete polymerization of the resin and to have only a carbon residue); and siliconizing such shaped and cured mixture. The resulting product has been formed to be denser and stronger, and more oxidation- and abrasion-resistant than prior art compositions.

Abstract: A fabrication process is disclosed that achieves a higher density carbon-bon article, than the prior art processes by maintaining a vertical temperature gradient in a reservoir of pitch (e.g. 550.degree. C. at the bottom to 250.degree. C. at the top) into which a carbon fiber preform is immersed. The use of the vertical temperature gradient results in a reservoir of hot fluid pitch around the upper end of the preform during pitch impregnation of the preform. This permits the fluid pitch to drain down by gravity into the interstices of the carbon fiber and the hardening pitch below. The next step of the process involves gradually increasing the pitch-hardening temperature from bottom to top to harden the pitch from bottom to top. Thereafter, the impregnated preform is carbonized at high temperature. This method takes advantage of the thermal conductivity of the carbon fibers and does not require extremely high pressures. In fact, a high pressure would be a detriment since it results in closed pores.

C., for about 10-60 minutes; and(g) cooling the pellets in an inert gas.

Abstract: Rigidized composite preforms are fabricated by first serving individual reinforcement strands with a thread of a thermoplastic material. After shaping the reinforcement strands into a desired geometry, the shaped strands are heated to melt the thermoplastic threads. By then cooling the shaped reinforcement strands, the thermoplastic material solidifies and acts as an adhesive or glue in holding the preform together in a rigid fashion. Such rigid preforms are particularly suitable for handling, storage and transportation to other locations and media prior to densification. Densification may be performed by conventional techniques to produce the final composite article. Pyrolysis of the matrices and subsequent densification of the matrix may be accomplished.
