Cryogenically treated goat and human hair reinforced hybrid polymer composites

Composites of epoxy resin reinforced with goat and human hair were obtained and subjected to cryogenic processing for 24 hours at temperature 77 K. Morphological (SEM), mechanical and thermogravimetric analyses (TGA) were performed. The best properties were obtained by using a reinforcement consisting of 60 wt% human hair and 40 wt% goat hair. The SEM confirmed good interactions at the interface for this composite.
