Apparatus for reinforced plastic molding Reeves, J. F. (Private inventor) US Pat 3 704 970 (5 Dec 1972) An apparatus for moulding insulated reinforced plastic structures for use as refrigerated cargo trailers and vehicle bodies. It consists of glass fibres including an insulating core material, which are impregnated with a free flowing liquid resin which also wets the surfaces of the core material. Glass fibre reinforced elastomers Marzocchi, A. (Owens-Corning Fiberglass Corp) US Pat 3 705 052 (5 Dec 19 72) A method for improving the bonding of glass fibres to elastomers in which the fibres are treated to give them a metal oxide surface followed by a thin surface coating of xanthate or a carbonate. Glass fibre bundle comprising an elastomer compatible impregnant and a thickening agent Marzocchi, A. (Owens-Coming Fiberglass Corp) US Pat 3 705 073 U Dec 1972) Improvement in bonding between glass fibres and elastomers in the manufacture of glass fibre reinforced elastomeric composites is obtained when individual glass fibres are sized, or a bundle of glass fibres is impregnated with an elastomer compatible material which has been rendered thioxotropic by the addition of a thickening agent. Glass fibre reinforced elastomers Marzocchi, A. (Owens-Coming Fiberglass Corp) US Pat 3 705 075 (5 Dec' 1972) Improvement in bonding between glass fibres and elastomers is obtained by coating individual or bundles of glass fibres with a composition including as a glass fibre anchoring agent a resorcinol silicon conrpound or a resorcinolato chromic complex. Material for bonding resins to glass fibres and composites made therefrom Preston, J. A. and Davis, C. J. (OwensCorning Fiberglass Corp) US Pat 3 705 125 (5 Dec 1972) An improved bonding material comprising a hydrolysed siloxane and a polyimine which is dispersible in the siloxane. The coating is preferably applied to glass fibres on forming an aqueous solution, the coated fibres are used to strengthen a matrix resin which is fused with the coating material

so that diffusion of the polyimine into the matrix resin takes place. Composites of these fibres with matrices that are reactive with amine hydrogen have high strength. Producing sintered alumina fibres from an alumina strip of very high solids content Pearson, A. and Marhanka, J. E. (Aluminium Co of America) US Pat 3 705 223 (5 Dec 1972) Using dispersing agents, slips formed of a volatile fluid and containing 80 to 90% of discrete a alumina particles with a median diameter of 0.3-2.5/a and having a viscosity >5 000 cp are made, this being formed into threads in an evaporative environment to concurrently remove a portion or all of the liquid ingredient thus forming self supporting fibres which are then sintered. Method of producing carbon fibres lshikawa, T. and Teranishi, H. (Nippon Carbon Co Ltd) US Pat 3 705 236 (5 Dec 1972) Carbon fibres having a tensile strength o f > 1 5 0 kg/mm 2 and a Young's modulus of >32 000 kg/mm 2 are prepared by applying a vibrational energy to organic fibres under a tension during at least one step in the fibre production process. Method of producing composite sheets composed of polymeric fibres and elastic material Toki, M. and Hikota, T. (Toray Industries lnc) US Pat 3 706 613 (19 Dec 1972) A composite sheet substance having similar appearance and physical properties to leather is manufactured from fibrous material comprising many fine fibres and an elastic polymer matrix surrounding these fibres. Fabrication of a composite material by uniting thin fibre coated polymerizable plastic sheets Kirkpatrick, M. E. and Reger, J. L. (TRW lnc) US Pat 3 706 614 (19Dec 1972) Micron-size elongated particles or fibres of high strength material are dielectrophoretically deposited on a thin substrate of low strength material so that the fibres are aligned parallel to each other in a layer of micronsize thickness. A mulitplicity of such fibre coated substrates are laminated, bonding to form an integral structure.

Composite tube and a method of producing same using the filament winding process Nishiyama, S. and Kusano H. (Kubota Iron and Machinery Works Ltd) US Pat 3 706 615 (19 Dec 1972) A composite and method of production are described, the tube consisting of inner and outer layers of glass fibre threadg impregnated with a thermosetting resin and an intermediate layer(s) of a sheet material of paper or cloth coated with a thermosetting resin or a mixture of a thermosetting resin and additives such as sand. Reinforced polyphenylene ether compositions Nakarishi, A. and lzawa, S. (AsahiDow Ltd) US Pat 3 708 455 (2 ,/an 1973) Polyphenylene ether compositions reinforced with glass fibre have excellent processability. They are prepared from blends of 10-50% by weight of glass fibre and from 90-95% by weight of a resin matrix. Polycondensate reinforcement process using an interfacial forming technique Kardos, J. L. (Monsanto Co) US Pat3 708 456 (2 Jan 1973) Fibre reinforced condensation polymers are made by conducting an interfacial polycondensation without substantial stirring in the presence of discontinuous inorganic reinforcing fibre dispersed in the phase through which the interfacial film of polycondensate is withdrawn from the reaction zone.

Method of manufacturing strips containing aligned fibres (Philips Electronic and Associated Industries Ltd) UK Pat 1 292 894 (18 Oct 1972) Aligned fibres are held in the same direction by a resin binder; a continuously moving strip shaped support is contacted with a fibrous suspension flow surface, deposited fibres being moved away from the surface. Process for the production of fibres, textiles and shaped articles composed of inorganic .materials (Union Carbide Corp) UK Pat 1 292 908 (18 Oct 1972) A preformed polymeric material is impregnated with at least one compound which at >740°C is solid or
