The effect of eggshell particles on the mechanical properties of epichlorohydrin crosslinked chitosan/eggshell composites had been studied. The content of eggshell particles in each composites was varied from 2.5 to 13.4% (w/w). The tensile strength was 60% improved, compared to the control chitosan showed the optimum tensile strength. The improvement tensile strength was 60% comparing with control chitosan. XRD patterns exhibited the decrease in peak intensity of chitosan at 2q = 20^o due to te addition of epichlorohydrin as a crosslinking agent of chitosan and incorporation of eggshell particles to crosslinked chitosan. The peak intensity at 2q = 44^owas increased due to the addition of eggshell particles. Scanning elecron microscopy images confirmed the eggshell particles was dispersed into chitosan matrix.
