Project Objectives

The objective of the proposed research is to manufacture composite products using soy protein based polymers.


Project Abstract

Soy protein has been considered as a potential alternative to petroleum polymers in the manufacture of plastic and fiber reinforced composites. Soy based plastics and composites can be used to replace traditional materials like steel, aluminum, concrete and wood. Glass fiber and natural fiber reinforced composites will be manufactured using compression molding process. Mechanical tests will be conducted and the results will be compared with simulation results. The use of soy protein based polymer coupled with process development will offer affordable and durable products.


Anticipated Benefits

Use of soybean-derived materials offer low cost raw materials and environmentally sustainable benefits.


Modal Orientation
