EMULSION TYPE SIZING AGENT FOR CARBON FIBRE

Epoxy resin AG 80 was emulsified with different emulsifier mixtures and the effect on its emulsification was studied by the static precipitation method. The mixture of emusifier1601 and NP 10 is considered the best. The most probable size of an emulsion particle is 934.1?nm, at which the emulsion stability is excellent. The interfacial shear strength of single fibre composites is improved by sizing. Results show that this sizing surface treatment not only protects the carbon fiber surface, but also improves the fiber adhesion to the resin matrix.
