Abstract

Drilling is a principal machining process that is generally operated to make holes in composite parts to join and assemble into a complicated structures. Recently, the use of natural fiber composites (NFCs) has increased in engineering and industrial applications. Choosing an appropriate non-destructive technique to evaluate the drilling-induced delamination in NFCs is a vital and essential task. This paper investigates three different non-destructive techniques for evaluating and determining the size and shape of drilling-induced delamination in NFCs. According to the results from this research, it can be inferred that the image processing technique using a flatbed scanner can be utilized as an accessible, economical, and efficient method for assessment of drilling-induced delamination in NFCs.
