Nondestructive testing method for Kevlar and natural fiber and their hybrid composites

Abstract This chapter highlights the nondestructive testing (NDT) method used for Kevlar and natural fiber and their hybrid composites. This chapter also provides various hybrid composites between synthetic-synthetic fiber, natural-synthetic fiber and natural-natural fiber, types of defects in composites, and methods of NDT used to detect and identify defects in various composites. From the review, NDT methods are widely applied in detecting defects in composites made from synthetic fiber. However, there are limited resources in NDT methods for composites from natural fiber, especially for hybrid composites between natural-natural fiber. Since more research is being conducted in hybridizing composites with natural fiber, modification or development of state-of-the-art NDT techniques for the inspection of such composites is necessary.
