US Patent:

43776574, Mar 22, 1983

Filed:

Mar 30, 1981

Appl. No.:

6/248978

Inventors:

Sidney W. Street - Hacienda Heights CA
Don A. Beckley - Newport Beach CA

Assignee:

HITCO - Irvine CA

International Classification:

C08L 3900

US Classification:

524424

Abstract:

A novel bis-imide matrix resin system comprising 50 to 95 percent by weight of ethylenically unsaturated bis-imides, preferably a low melting mixture of a major portion of maleimides of aromatic amines with a minor portion of maleimide of an aliphatic amine and 5 percent to 35 percent by weight of a diunsaturated low-temperature cross-linking agent such as divinyl benzene which gels the bis-imide at low temperatures. This reduces stress between the matrix resin and the surface of the reinforcing fiber, thus reducing the tendency to form microcracks. Microcracking is further reduced and transverse strength is increased by the addition of 0 to 15% of compatible elastomers to the resin and cross-linking agent. Room temperature tackiness, heat resistance and cross-link density are improved by the presence of 0 to 10% of a trifunctional curing agent.

524261

Abstract:

A processable blend having high temperature and thermal shock resistance properties includes a resin blend which includes at least one first silicone polymer and at least one second silicone polymer. The processable blend is ceramitizable at a temperature above about 1100. degree. F. A method of producing an article with high temperature and thermal shock resistance properties includes forming a silicone blend of at least one first silicone polymer and at least one second silicone polymer, wherein the blend is ceramitizable at a temperature above about 1100. degree. F. ; forming the blend into the shape of the desired article; and, at least partially curing at least one of said silicone polymers at a temperature below the ceramitization temperature.

International Classification:

C08L 3904

US Classification:

525422

Abstract:

A novel bis-imide matrix resin system especially useful for high temperature, high performance, graphite fiber composites is disclosed. Microcracking of composites is reduced and transverse strength is increased by the addition to the resin system of 1 to 15 percent of compatible elastomers, such as polyether sulfones, bis-phenol linear homopolymeric epoxies or polyacrylic esters. The resin system comprises 50 to 95 percent by weight of ethylenically unsaturated bis-imides, preferably a low melting mixture of a major portion of maleimides of aromatic amines with a minor portion of maleimides of an aliphatic amine and 5 percent to 35 percent by weight of a diunsaturated low-temperature cross-linking agent such as divinyl benzene which gels the bis-imide at low temperatures. Room temperature tackiness, heat resistance and cross-link density are improved by the presence of 1 to 10 percent of a trifunctional curing agent.

Appl. No.:

5/739039

Inventors:

Don A. Beckley - Newport Beach CA

Assignee:

Hitco - Irvine CA

International Classification:

B29C 2704

US Classification:

156272

Abstract:

A high temperature woven refractory fabric is coated by preheating the surface of the fabric by means of actinically matched radiation, suitably infra-red, and then fusion-bondingthe inner surface of a thermoplastic film such as polyurethane to at least one surface of the fabric to fusion-bond the film thereto. The warm fusion-bonded film is then processed through a non-heated nip-roll assembly in which at least one of the rollers has a soft facing such as rubber which impresses the film into the interstitial fill-weft woven intersections to form a fabric-appearing coated product. The infra-red wave length is selected for maximum absorption by the fabric and the intensity of the radiation and speed of the film are controlled to provide sufficient but not excessive fusion or melting of the film. The coating apparatus includes a control device in which an infra-red sensing non-contact thermometer senses the temperature of the fabric as it leaves the infra-red heater and develops a control signal that controls the speed of the fabric through the system.

Abstract:

Improved graphite composite electrodes are provided by rendering the matrix resin conductive by dispersing therein 5 to 15% by weight of a conductive pigment and by uniformly dispersing therein randomly oriented graphite fibers having a diameter below 30 microns and a length no more than 1/2 the thickness of the electrode plate. The electrodes are particularly useful in the disinfection of aqueous liquids with low power consumption and with very low ablation of the surface of the electrode.
