Molded specimens of high-density polyethylene (HDPE)/jatropha deoiled cake (JOC) composites are presented on page E-78 by T. Elshaarani, Z. Yaakob, M. D. Khairul Zaman, M. Mohammad, and S. R. S. Abdullah. The morphology of the tensile fractured composites is investigated by scanning electron microscopy. The image shows that the composite agglomerated and distributed in a large and broad size with many gaps between the cake and the polyethylene matrix. This is probably due to poor dispersion and inadequate wetting of the fiber inside the matrix, indicating incomplete interfacial bonding between the cake and the matrix during the composite blending.
