Title: THE EFFECT OF INTEGRATED BIO-COMPOSITES INTO COMPOSITE STRUCTURES  

 

Abstract: There is an increasing demand for cheap, yet light, robust structures in automobile body frames. Current major composites can be very costly. The introduction of a bio-composite as a replacement for a segment of these major composites can greatly reduce costs while maintaining a similar structural integrity. Three different three-layered skin arrangements were constructed from the following materials: hemp, carbon fiber, and carbon fiber-hemp. Corrugated structures were manufactured with these arrangements to be tested under compressive loads. The corrugated structures were varied in ligament size, where a ligament was defined to be one fold of the corrugation shape of constant length and thicknesses. It was found that an increase in number of ligaments increased the structures’ ultimate failure strength. A larger bonding surface area due to a higher number of ligaments allowed the structure to take in higher shear forces. It was also observed that under compressive loads, hemp outperformed carbon fiber due to its elastic properties that allowed hemp to deform with higher loads. The brittleness of carbon fiber led to catastrophic failure. When the individual materials were joined to make one, the resulting carbon fiber-hemp exhibited both of the individual materials’ properties and thus demonstrated the best performance.
