Mechanics and design of flexible composite fish armor
… overlapping scales found on teleost fish, a new composite architecture explores the mechanics of materials to accommodate both flexibility and protection. These biological structures consist of overlapping mineralized plates embedded in a compliant tissue to form a natural flexible armor which …

Mechanics of Flexible Composite Hull Panels Subjected to Water Impacts
… measurements of the loading and responses of flexible hull panels during slamming events. Significant research into slamming loads and pressures has previously been undertaken, dating back to 1929, however there is a lack of experimental data on flexible structures accurate enough to allow for …

Integrated strain actuation in aircraft with highly flexible composite wings
… by integrating anisotropic piezoelectric composites (APC) within the passive composite wing skin. The goals include the ability of integrated strain actuation (ISA) to provide sufficient wing deformation for roll maneuver, gust load alleviation, flutter suppression, and redistribution of …

Biological and bio-inspired morphometry as a route to tunable and enhanced materials design
… through the development of bio-inspired, flexible composite armor based on the articulated exoskeleton of an armored fish, Polypterus senegalus, which achieves uniform coverage and protection from predatory threats without restricting flexibility. First, the functional implications of …

Nanostructured thin film thermoelectric composite materials using conductive polymer PEDOT:PSS
… into modem society. To combat these issues, composite materials that use conductive polymers have been under investigation due to their low cost, manufacturability, and malleability. These new composite materials could lead to cheaper thermoelectric devices and even introduce the technology …

Local plastic deformation in pressure and tensile armour layers of flexible risers
<p>Flexible pipes are commonly used for connecting seabed flow-lines to floating production facilities. The general riser design consists of an internal carcass for collapse resistance, a polymer fluid barrier, carbon steel interlocked circumferential pressure armour layer for resisting internal …

Long-Term Modelling of Composite Pavement Performance
… which results in a structure known as a composite pavement. The most common form of distress in this type of pavement is reflection cracking which can be due to traffic and/or climatic loading. This thesis is focused on the prediction of reflective cracking as a composite pavement …

An Experimental Study of the Fluid- Structure Interactions of Water Entry of Compliant Structures
… fields of engineering. In the case of highly flexible panels, an application for this topic is on drag reduction due to shape reconfiguration of panels near the free surface to support further development of undulatory propulsors. Moreover, it has been an important concept in the study of the …

Heterogeneous Distribution and Corresponding Mechanical Significance of The Mineral Phase in Fish Scales
Fish scales can be considered as a laminated composite based on collagen fibrils arranged in a cross-plywood structure. This collagen-based composite is often partially mineralized (primarily hydroxyapatite) in the scale exterior in order to resist penetration and hence to enhance protection. …

Characterization, Processing, and Synthesis of Extreme-Performance Continuous Carbon Nanotube Network Composites
… fiber reinforcements for extreme-performance composites. Yet because the constituent CNTs interact only via intermolecular forces, network properties fall short of their building blocks. Although these materials show promise as reinforcement in composites, the networks’ low-permeability and …
