A sizing composition for fibres especially carbon fibres and other organic fibres such as glass fibres comprises: (a) an epoxy resin or a mixture of epoxy resins; and (b) a thermoplastic polyhydroxyether which is a substantially linear polymer having general formula (I), where D is the radical residuum of a dihydric phenol, E is a hydroxyl-containing radical residuum of an epoxide, and n (the degree of polymerisation) is at least 30 and is preferably 80 or more. The composition may also include (c) a vehicle for components (a) and (b) which is a solvent therefor or an aqueous medium incorporating an emulsifying agent therefor, and (d) a water-insoluble high-boiling-point solvent for the epoxy resin component (a). |
