Book Description
A theory of local and global mechanisms of heat generation and distribution in carbon-fiber-based composites subjected to an alternating magnetic field has been proposed. A model that predicts the strength and distribution of thermal generation through the thickness of carbon-fiber-based laminated composites has been developed. Earlier work has established the distribution of point voltages in the plane of the laminate that exist in the form of potential differences between fibers in adjacent plies in a cross-ply or angle-ply laminate system. In this work a capacitive-layer microstructure that models the actual fiber-reinforced-polymer microstructure from a square-packing assumption to a series of conductive parallel plates is formulated. An effective parameter of heating, gamma, that establishes the distribution of heating through the thickness is defined. Extreme gradients in this thermal source can exist with peaks occurring at the interfaces of ply-ply orientation changes. An optimization study establishes the effect of various microstructural and macrostructural parameters on the heating parameter, gamma. Several parametric studies are performed on the computer algorithm, which calculates gamma to further analyze these effects.

Book Description
Heating of continuous carbon-fiber-reinforced polymers (CFRP's) by the application of an alternating magnetic field has been shown to be due to dielectric losses in the polymer. Models that predict thermal generation in these composites are input to a finite element heat-transfer analysis, providing the predicted transient thermal profile in the plane of the laminate. The validity of the global thermal generation model is established through an experimental test matrix in which various specimen configurations are evaluated and compared with theoretical predictions of transient surface temperatures.

Book Description
Composite structures are most efficient in performance and production cost when combined with smart materials making them adaptable to changing operational conditions. The specific production processes of composites offer the possibility to integrate more functions thus making the structure more valuable. Active functions can be realized by smart materials, e.g. morphing, active vibration control, active structure acoustic control or structure health monitoring. The foundation is a sound understanding of materials, design methods, design principles, production technologies and adaptronics. Along the complete process chain this disciplines together deliver advanced lightweight solutions for applications ranging from mechanical engineering to vehicles, airframe and finally space structures. This book provides the scientific foundations as well as inspiring new ideas for engineers working in the field of composite lightweight structures.
