Method of manufacturing a fiber reinforced composite material Heissler, H., Hitsch, E. and Scheer, W. (Maschinenfabrik Augsburg-Nurnberg Aktiengesellschaft) US Pat 4 050 997 (27 September 1977) A process for producing reinforcing carbon fibres is described. The fibres comprise a carbon fibre substrate with a light metal or metalloid coating. Composite of rubber bonded to glass fibers van Gils, G.E. and Kalafus, E.F. (The General Tire & Rubber Company) US Pat 4 051 281 (27 September 1977) A glass fibre reinforcing element is bonded to a rubber compound using a composition comprising an aqueous alkaline suspension of a rubbery vinyl pyridine copolymer, timethylol phenol, a rubbery vinyl pyridine copolymer trimethylol phenol, a thermoplastic and non heat hardenable resorcinol NH4 OH or NaOH and water.
Carbon fibre is made from a multifilament tow of organic precursor fibre, heated in an oxygen containing atmosphere, carbonised and, optionally, graphitised. The fibre is twisted between the oxygen treatment and carbonisation to keep the fibres within the tow. Method and apparatus for making fiber reinforced tape Chen, H.T.

Process for reinforcing aluminium alloy Riewald, P.G., Krueger, W.H. and Dhingra, A.K. (E.I. Du Pont de Nemours and Company) US Pat 4 053 011 (11 October 1977) Polycrystalline alumina fibres are placed in a mould. A composite reinforced with 10-80% of fibres and having a porosity of less than 10% is
then formed by infiltrating the fibres in the mould into a molten aluminium alloy (containing 1-8% Li) for long enough for a sheath to form around the fibres. Reinforced filament-wound cut-port pressure vessel and method of making same Minke, C.M. (The United States of America - Secretary of the Navy) US Pat 4 053 081 (11 October 1977) The vessel is wound at a constant helical winding angle that can be predetermined and has polar end openings one of which is larger than the other. Fiber reinforced plastic handrail system Clemens, D.L. and Edmiston, S.A. US Pat 4 053 140(11 October 1977) The method of construction of the handrail is described.
