About this book

This book provides valuable information about fiber-reinforced polymer composites, with emphasis in the process of water absorption by experiments and simulation. In this monograph, we present and discuss emerging topics related to fundamentals, engineering applications, advanced mathematical modeling applied to Fickian and non-Fickian diffusion processes, analytical and computational procedures and experiments on water absorption of polymer composites reinforced by vegetable fibers. The book serves as a comprehensive learning tool for engineers, professionals, and researchers involved in this advanced interdisciplinary field, and as a reference work for both undergraduate and graduate courses.

Chapter 1. Introduction
Abstract
This chapter provides several information about polymer composites with emphasis on vegetable fiber-reinforced polymer composite materials, as well the motivation to study the water absorption process in these materials. Herein, we present and discuss different topics such as definition, classification, constituents, technological characteristics, manufacturing techniques, performance and applications of polymer composites.

Chapter 2. Fundamentals
Abstract
This chapter focuses on the water diffusion process in composites materials. Special attention is given to vegetable fiber reinforced polymer composites. Herein, the main issues related to this important topic such as foundations, advantages and problems associated with the use of vegetable fibers as reinforcement in polymer composites are discussed, especially that caused by weak adhesion and exposure to the hot and humid environments, are presented and discussed.

Chapter 3. Experimental Analysis
Abstract
This chapter provides experimental information on water absorption in unsaturated porous media, with particular reference to vegetable fiber-reinforced polymer composites. Herein, important information related to fiber morphology, manufacturing, moisture absorption, mechanical caracterization tests in polymer composites reinforced by caroá, macambira, sisal fibers are presented in detail.Results of the fiber morphology, moisture gain kinetics, for different sample thickness, process temperature, mechanical properties (tensile strength, elastic modulus, impact resistance, elongation) are shown, analyzed.

Chapter 4. Fick’s Model Analysis
Abstract
In this chapter, based on the rigorous theory of pure diffusion through fibrous porous media (Fick’s second law), different approaches (analytical, numerical and by CFD) and its limitations for the correct description of water absorption process in vegetable fiber-reinforced polymer composites will be presented. In the macroscopic mathematical modeling both fiber and polymer are considered to be a homogeneous mixture and the effect of swelling was not taken into account. Herein, by using a three-dimensional mathematical treatment, different effects of some process parameters (sample thickness and water bath temperature) in the moisture migration behavior inside the material were analyzed. Applications were perfomed on polyester composites reinforced by caroá and macambira vegetable fibers.

Chapter 5. Langmuir-Type Model Analysis
Abstract
In this chapter, based on the rigorous theory of anomalous diffusion through fibrous porous media (Langmuir-type model), its advantagens, limitations, and different approaches (analytical and numerical), we present the correct prediction for the water absorption process in vegetable fiber-reinforced polymer composites.

Chapter 6. Conclusions
Abstract
This book is entirely dedicated to diffusion processes in polymer composites, with particular reference to moisture absorption in vegetable fiber-reinforced polymer composites.
