Oguocha Preface Composite materials are being more frequently used in a wide range and variety of structures, such as automotive and aerospace components. Composite materials often demand a unique combination of properties, including high thermal and oxidative stability, toughness, solvent resistance and low dielectric constant. This book is comprised of seven excellent chapters, written for all specialized scientists and engineers dealing with characterization, thermal, mechanical and technical properties, rheological, morphological and microstructure properties, and processing design of composite materials. Chapter 1 reports novel thermoplastic polyimides (TPI) resins reinforced with carbon fiber (CF), glass fiber (GF), and modified by adding of solid lubricates such as graphite (Cr), poly(tetrafluoroethylene) (PTFE) or molybdenum disulfide (MoS2) to give TBI molding particulates, which could be injection-molded at elevated temperature to give the TPI composite materials. The thermal and mechanical properties of the pure TPI resin, the molding particulates and the molded composites were systematically characterized. Thermoplastic polyurethanes (TPU`s) are a multipurpose group of phase segmented polymers that have good mechanical and elastic properties and hardness. Usually, TPU`s exhibits a two-phase microstructure. Fumed nanosilicas are added to increase the thermal, rheological and mechanical properties of TPU`s. Chapter 2 studies the effect of incorporating hydrophilic fumed nanosilica in the formulation of polyurethane adhesive with different NCO/OH to improve its thermal, rheological and adhesive properties. Chapter 3 involves manufacturing techniques developed for composite structural insulated panels (CSIPs) on the construction site. Detailed description about the manufacturing CSIPs is included in this Chapter. The Chapter also covers manufacturing of the traditional structural insulated panels (SIPs) in the panelized construction. Cure induced phase separation (SIPS) is an important part of reaction-induced phase separation (RIPS) due to its innovative applications to composite processing, or, more generally, to the innovations of multi-phase polymers. Chapter 4, provides a concise VIII Preface summary of up-to-data original contribution relevant literatures in this field emphasizing the breakthrough in approaches to understanding and controling the CIPS during the process. Thermoplastics have some distinct advantages over thermoset composites, such as high ductility and toughness, facility of processing and recycling potential. The purpose of Chapter 5 is to compare two methods of processing thermoplastic composite hot compression molding and aqueous suspension prepregging, showing that the latter method uses the insertion of a polyimide interface in the composite. Chapter 6 gives the reader a complete understanding of the thermoplastic nanocomposites and their processing techniques, polymer interaction, their resulting properties and proposed application. In Chapter 7, differential scanning calorimetry (DSC) and heat flowmeter method are used to determine the non-isothermal crystallization behavior and thermal conductivity of polypropylene (PP) and its composites, reinforced or filled with different weight of fractions of biofibers.
