Composite materials are blends of two or more materials of different physical properties. The individual materials are immiscible with each other and exist as distinct phases. Thus, composite materials are multiphase materials consisting of two or more phases. Different materials are mixed together with the purpose of generating superior materials having properties better than those of the individual materials. Composite materials are a rapidly growing class of materials, with applications in industries such as plastics, automotive, electronic, packaging, aircraft, space, sports, and the biomedical field.
In the design, processing, and applications of composite materials, a thorough understanding of the physical properties is required. It is important to be able to predict the variations of the electromagnetic (electrical conductivity, dielectric constant, and magnetic permeability), mechanical, thermal (thermal conductivity and coefficient of thermal expansion), and mass transport properties of composite materials with the kind, shape, and concentration of filler materials. The filler material may consist of equiaxed particles ranging anywhere from nanometers to microns in size, discontinuous short fibers or whiskers, small disk- or plate-shaped particles/flakes, or core-and-shell type of complex particles.
A number of excellent books are available on composite materials, but for the most part, they are restricted to classification, applications, and manufacturing of composite materials along with the characterization of mechanical properties. The electromagnetic, thermal, and mass transport properties of composite materials have generally received little attention as compared with the mechanical properties even though they are equally important from a practical point of view.
The study of electrical, dielectric, and magnetic properties of composite materials can reveal valuable information regarding the morphology and composition of such systems. For example, the dielectric probes could be used to probe the microstructure and to estimate the filler content of composites, especially when the dielectric constants of the individual materials are significantly different from each other. The electrical properties of composites are important in the design of plastics used in the electronics industry. Pure plastics tend to pick up electrostatic charges, especially under low-humidity conditions. When earthed, the (charged) plastics discharge and, in the process, damage electronic circuitry and equipment. To overcome the problems associated with electrostatic charge of plastics, electrically conducting filler particles (such as carbon black) are incorporated into the plastic matrix. The incorporation of electrically conducting filler particles into the plastic matrix imparts electrical conductivity to the plastic system, and as a consequence, the buildup of static charge is avoided. The magnetic properties of composite materials are of interest in many industrial applications involving electrical and electronic instruments, electrical power generators and transformers, electric motors, radio, television, telephones, computers, audio and video equipment, etc.
The thermal properties of composite materials are important in many practical applications. For example, knowledge of the coefficient of thermal expansion (CTE) of composites is required in calculating dimensional changes and buildup of internal stresses when composites are subjected to temperature changes. In designing a composite material, it is often necessary to match the CTE of different components. The other very important thermal property of composite materials is their thermal conductivity. In the electronics industry, the packaging material used to encapsulate electronic devices must have a high thermal conductivity in order to dissipate the heat generated by the device as rapidly and effectively as possible. Particulate composites consisting of polymer matrix and heat-conducting fillers are used for this purpose. Polymers filled with heat-conducting fillers provide the required thermal conductivity while maintaining the electrical insulation properties of the polymers. It has been recently discovered that the addition of a small amount of nanoparticles (such as carbon nanotubes and copper nanoparticles) can greatly improve the thermal conductivity of polymers.
The mass transport properties of composite materials are important in the design and application of composite membranes. Composite membranes are extensively used in the separation of gas mixtures. In the packaging industry, composite membranes are used as barrier films.
The aim of this book is to provide a systematic and comprehensive coverage of the electromagnetic, mechanical, thermal, and mass transport properties of composite materials.
Throughout the book, the analogy between various properties is emphasized. The book draws heavily on the work of the author on physical properties of composite materials.
The first chapter of the book discusses the important applications of composite materials and the relevance of electromagnetic, mechanical, and transport properties. The book is then organized in three parts: Electromagnetic properties of composites (Sections I and II), Mechanical properties of composites (Section III), and Transport properties of composites (Sections IV and V). Section I, titled Static electromagnetic properties of composites, deals with the electromagnetic properties of composite materials subjected to time-invariant electric and magnetic fields. It consists of three chapters. Chapter 2 describes the electrical conductivity of composites, Chapter 3 the dielectric properties, and Chapter 4 describes the magnetic properties of composites. Section II, titled General treatment of electromagnetic phenomena in composites, deals with the dynamic electromagnetic properties of composite materials subjected to time-varying electric and magnetic fields. This section consists of two chapters. Chapter 5 deals with the fundamental aspects of electromagnetic phenomena. The general laws of electromagnetism (Maxwell equations) and the generalized conductivity principle are discussed. Chapter 6 describes the complex electromagnetic properties of composites. The frequency dependence of electromagnetic properties of composite materials is also discussed in details. Section III (Mechanical properties of composites) consists of seven chapters. Chapter 7 describes the mechanical properties of dilute particulate-filled composites. The mechanical properties of concentrated composites are described in Chapters 8 through 11. The influence of interfacial and interphase effects on the mechanical properties of composites is discussed in Chapter 12. The viscoelastic behavior of composite materials is covered in Chapter 13. Section IV, titled Heat transfer in composites, consists of seven chapters. Chapters 14 and 15 cover the fundamental aspects of heat transfer. Chapters 16 and 17 describe the thermal conductivity of particulate composites. The influence of interfacial contact resistance on the thermal conductivity of composites is covered in Chapter 18. The thermal diffusivity and coefficient of thermal expansion of composites are dealt with in Chapter 19. The radiative heat transfer properties of composite materials are described in Chapter 20. Section V, titled Mass transfer in composites, consists of Chapters 21 through 24. Chapter 21 covers the fundamentals of diffusion mass transfer. The diffusion mass transfer in composite membranes is described in Chapter 22. Chapter 23 deals with the fundamentals of convective mass transfer, and Chapter 24 covers convective mass transfer in composite materials.
