Abstract

1,128,321. Forming threads from fibre dispersions. MINISTER OF TECHNOLOGY. 30 Sept., 1965 [1 Oct., 1964], No. 39954/64. Heading B5B. [Also in Division C3] Fibres are aligned for embedding in a material to produce a fibre reinforced composite material by dispersing the fibres in a viscous liquid medium, extruding the dispersion through an orifice to align the fibres, treating the extruded dispersion to form the liquid medium into a solid carrier for the aligned fibres and removing the solid carrier from the fibres whilst maintaining their alignment. The fibres may be glassfibres, single crystal whiskers, e.g. of silicon nitride, or asbestos fibres. In one embodiment the liquid is a solution of ammonium alginate. The dispersion is extruded into a thread, ribbon, or tape which is solidified by treatment with an acid. The solid carrier is decomposed by heat either when the thread &c. has been cut and arranged in a desired configuration or when the thread has been wound on a frame. Alternatively the liquid medium may comprise a gelatine solution, or a plasticized polymer, e.g. polyvinyl alcohol or polystyrene. The aligned fibres may reinforce a resin, e.g. epoxide or phenolformaldehyde, or a metal composition. Powder of the metal or other material may be added to the dispersion before extrusion. The fibres may be precoated with the metal or be treated with a detergent.
