Abstract Scope |
This work investigates the viability of casein protein for manufacturing engineering structures. Polyamide 12 (PA12) was used as a matrix for different compositions of casein up to 15%. Test samples were fabricated for neat PA12 and the composites using selective laser sintering for tensile, impact, and flexural strengths comparisons. The results show significant increases of the tensile strengths up to 71% for the composite materials over the neat PA12. Stiffnesses also increased up 157% while the ductility reduced by at least 45%. Flexural strengths increased significantly for all casein compositions and treatments up to 135%. However, impact strengths reduced significantly for all the composites, except for the plasticized samples that demonstrated marginal differences with the neat PA12. This investigation shows the dependencies of mechanical properties on the type of filler casein and treatments. |
