Potential of natural/synthetic hybrid composites for aerospace applications

The term hybrid composites is now becoming of key importance from an economical and ecological compatibility point of view. These are materials made up of two or more different natural and synthetic fibers, reinforced with suitable polymer matrices to form a composite material that include properties comparable to that of manmade materials. Also, in order to keep up with modern technological trends, it has become mandatory to develop materials which are less hazardous to nature so that our environment can be preserved for many more years. This concept has encouraged humans to use hybrid composite materials in applications for daily life. The advantageous properties of these composites, such as cost-effectiveness, recyclability, and biodegradability, have also made these materials a great substitute for synthetic materials which can be used in various applications. In this regard, in this chapter, a collaborative effort has been made to give an overview of different natural and synthetic fibers, their classification, and their applications in various engineering applications, and finally a discussion on hybrid composites and their various properties is included.
