In this paper the results of an extensive study will be presented of regenerating performance of thermally conditioned glass fibre using hydrofluoric acid (HF). The effectiveness of HF was investigated on strength recovery of glass fibres thermally conditioned in a typical temperature range for glass fibre recycling. The chemical treatment was also applied to glass fibres directly recycled from epoxy composites using a fluidised bed technique. The effect of treatment time on fibre strength was studied. A significant increase of fibre strength was obtained through the HF treatment and apparent reduction of fibre diameter suggested that strengthening mechanism was associated with HF etching. SEM/EDX was used to examine the surface alteration caused by the HF treatment.
