Chapter Three - Hybrid natural fiber composites in civil engineering applications

Abstract

This chapter is aimed to cover the recent developments in hybrid natural fiber composites used in civil engineering and construction. The replacement of synthetic fibers with natural fibers has been one of the most sought after research areas in the recent past. The attributes like the economy, low density with high specific strength and stiffness, biodegradability, renewability, and environment-friendly nature have made natural fibers a viable choice in the civil engineering sector. The application of natural fibers along with synthetic fibers in retrofitting of existing structures, strengthening of concrete and soil are reviewed in this article. The effect of fiber treatment and laying pattern, on the mechanical properties, durability, and weatherability of hybrid natural fiber composites are discussed in detail. The development of novel wood flour filled microfibrillar composites from waste plastics for building materials is also presented.
