**5.2 Application of sisal fibre in railways**

Composite materials offer some huge benefits to metals in numerous underlying applications in rail lines such that they are lightweight, practical, consumption safe, energy-lessening underway, and stuff and fire retardant. Composite materials can be utilized in rail routes, the stuff case, primary entryways, gear racks etc.

### **5.3 Prospects for the use of sisal fibre in construction industries**

The addition of fibre strengthening in building materials can improve a lot of the manufacturing properties of the essential resources, such as fracture toughness, flexural strength and resistance to fatigue, impact and thermal shock. In few years, a huge deal of attention has been made all over the worlds on the possible application of natural fibre-based materials and on other construction materials. Research have been done in various nations on different properties such as mechanical physical properties, and toughness of concrete-based matrix toughened with natural fibres such as sisal, coconut, jute, bamboo and wood fibres. Natural fibres are good choice for strengthening of concrete-based materials due to their easy access, less prices as compared with synthetic fibres and less utilization of energy. In this chapter, an effort is made to describe the properties of the natural fibre-based composites [2–4, 22].
