**2. Mechanical properties of NFPCs**

NFPCs are different depending on the type of polymers or fibers employed, the processing condition and the characteristic properties developed after processing [32, 33]. The use of these NFPCs for structural applications depends more on the mechanical properties. There are different mechanical evaluations carried out on a material and some are very specific to individual application. However, the general focus of most researchers is on a few tests including tensile test, flexural test, impact test, compression test and hardness. These few tests can describe the mechanical behavior of any material to a large extent and also gives an insight to other possible areas of applications.
