Compressive behavior of walnut (Juglans L.) shell particles reinforced composite

Abstract

In the present paper walnut particle reinforced composite was developed in an open mould. Walnut particle reinforced composite was prepared with epoxy matrix with 10-40 weight percentage (wt%) of walnut particles and the effect of the reinforcement of particles on the water absorption capacity and compressive strength have been evaluated. The water absorption capacity was found to increase with increasing percentage of walnut shell particle. Ultimate compressive strength and Percentage reduction in length in compression increases with increment of walnut particle wt% remarkably. There was a major increase in ultimate compressive strength between 20 to 30 wt% of walnut shell particle with the maximum value of 50 MPa at 30 wt% of walnut particles. This study hence exploits the potential of walnut particle to be used in natural particle based composites.
