Project Objective

To manufacture composites using soy-based resin system and soyhull based foam.

Project Abstract

The cost of producing hollow or sandwich composite parts can be competitive with conventional materials. The soy-based resin system can be used as the matrix to bind the reinforcement package. The interaction between fibers and matrix is important in designing damage-tolerant structures. Composite panels with soyhull foam will be manufactured and characterized. The fiber/matrix/core interface will be studied to examine the level of bonding.

Anticipated Benefits

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