Abstract

In recent developments, Carbon Fiber Reinforced Plastics (CFRPs) components have drawn substantial attention in the aviation industry due to their environmental stability and lightweight properties. One of the most common machining operations carried out before the final assembly of any complex component is drilling, and drilling-induced delamination has drawn substantial attention from the research fraternity due to its impact on part rejection. Drilling thrust force plays a vital role in the delamination. In the present research study, the thrust force during the drilling of CFRPs is marginally suppressed using a passive magnetorheological elastomer. To incorporate passive MREs, a novel drilling fixture was designed and developed as per the design restrictions. The study comprises unidirectional and bidirectional fiber orientation to understand the impact of suppression of thrust force using the proposed novel approach. The result demonstrates the reduction of 13% and 16% in the drilling thrust force of unidirectional CFRP and bidirectional CFRP respectively, due to passive back-up provided by an isotropic MRE. Moreover, the present study also incorporates microstructural examination and its impact on reducing thrust force through scanning electron microscope examination. Microstructural examination reveals the layer wise damages and its effect on the unidirectional and bidirectional CFRPs.
