During the production of fiber-reinforced thermosets, the resin material undergoes a reaction that can lead to damage. A two-stage polymerization reaction is modeled using molecular dynamics and evaluations of the system including a fiber surface are performed. In addition, a phase-field model for crack propagation in heterogeneous systems is derived. This model is able to predict crack growth where established models fail. Finally, the model is used to predict crack formation during curing.

The potential application areas for polymer composites are vast. While techniques and methodologies for composites design are relatively well established, the knowledge and understanding of post-design issues lag far behind. This leads to designs and eventually composites with disappointing properties and unnecessarily high cost, thus impeding a wider industrial acceptance of polymer composites. Manufacturing of Polymer Composites completely covers pre- and post-design issues. While the book enables students to become fully comfortable with composites as a possible materials choice, it also provides sufficient knowledge about manufacturing-related issues to permit them to avoid common pitfalls and unmanufacturable designs. The book is a fully comprehensive text covering all commercially significant materials and manufacturing techniques while at the same time discussing areas of research and development that are nearing commercial reality.
Composite materials are used as substitutions of metals/traditional materials in aerospace, automotive, civil, mechanical and other industries. The present book collects the current knowledge and recent developments in the characterization and application of composite materials. To this purpose the volume describes the outstanding properties of this class of advanced material which recommend it for various industrial applications.

Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly.The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented.
