Thermo gravimetric analysis study of kinematic parameters and statistical analysis for big sheep horn/scapula bone of Indian origin

Abstract

The current work focus on a novel biomaterial extracted from Indian origin Deccani-Big sheep horn/scapula bone for exhaustive thermal property study using Thermo gravimetric analysis (TGA) and statistical analysis study using log normal to determine the failure rate of brittle material. The TGA shows four regions, first region in the water reduction range, second region is plateau with no change in weight, third regionfor decomposition and last plateau showing stable final product. Broido, Coats-Redfern, Chang and Horowitz-Metzger approximations are employed to compute the activation energy (Ea) of samples during decomposition. The observed average mean tensile strength is 63.38MPa whereas with the help of Weibull distribution shows 64.55MPa with R2 as 0.94.
