Dynamic mechanical and thermal analysis (DMTA) has been used to study the effects of surface treatment of carbon fibres on the viscoelastic properties of composites containing them. The fibres were treated by dip-coating, electro-polymerization, and plasma polymerization, and the behaviour of these fibres is compared with that of fibres treated by ordinary commercial oxidation and sizing procedures. Analysis of the experimental results is made both in terms of conventional approaches to viscoelastic behaviour and of the power-law analysis of the glass transition in an attempt to obtain suitable parameters for the evaluation of the effects of surface treatment.
