The effects of particulate cow bone additions on the mechanical properties and thermal properties of cow bone particle reinforced and polyester matrix composite was evaluated to assess the possibility of using it as a new material engineering application. Cow bone particles reinforced with recycled low density polyester were prepared by varying the cow bone particles from 80%-20%, 70%-30% and 60%-40% of polyester and bone powder ratio by using hand layup compression method. The mechanical properties of the developed composite were investigated. Factorial design experiment was conducted as per...
