Epoxy based sandwich composite using three-dimensional integrally woven fabric as core strengthened with additional carbon face-sheets.

Sandwich composites are three-dimensional (3D) composite structures that offer higher stiffness with overall low density. However, they suffer from low strength; thus, not suited for load bearing applications. In this work, an attempt is made to develop a high strength lightweight sandwich composite suited for load-bearing applications.

Analysis of Intramaxillary and Mid-Face Skeletal Asymmetry in a Three-Dimensional Model With Complete Unilateral Cleft Lip and Palate.

Cleft lip and palate is the commonest congenital craniofacial anomaly and also affects the facial bones. In a unilateral cleft lip and palate (UCLP), there is asymmetry in the mid-face and also within the maxilla between the cleft and non-cleft sides. The aim of this study is to develop a 3-dimensional model of an UCLP skull from a patient's cone-beam computed tomography and measure the asymmetry.

Analysis of Stress Trajectories in Human Adult Cleft Skull.

The craniofacial skeleton is designed to withstand the functional forces during mastication. Distribution of these forces is along the stress trajectories that can vary in a cleft skull compared with a normal skull. In this study, the authors constructed finite element models of cleft and normal skull and subjected them for occlusal loading in the posterior teeth.
