Experimental study on drilling of jute fiber reinforced polymer composites

Abstract

The use of natural fiber composites is growing at a fast rate in terms of industrial applications due to their eco-friendly, recyclable, renewable nature, and low density/costs. Recently, jute fiber is being used as a reinforcement material in the development of natural fiber reinforced plastics for engineering applications. Drilling is an essential machining operation that is frequently performed for making of holes in composite structures to facilitate assembly of several components into a complex part. The literature reviews indicate that only a few of research articles investigated drilling of natural fiber reinforced composites. Hence, in the present research, drilling of woven jute fiber reinforced polymer composites has been examined. This study aimed at evaluation of cutting parameters and drill bit types effect on thrust force, delamination size, and surface roughness in the jute fiber reinforced polymer composites drilling using an experimental design based on full factorial technique. The percentage contribution of the cutting parameters and drill bit types were determined through the analysis of variance. The optimal setting of these parameters was found through observation. The experimental results indicated that the most significant effect was the drill bit type influencing both delamination factor and surface roughness.

Experimental Investigation on Machinability of Polypropylene Reinforced with Miscanthus Fibers and Biochar

“…This led to an increase in the resistance to chip formation, and subsequently, to the higher thrust force value. This result is consistent with other studies [5,7,[12][13][14]39,40]. It also indicates that the thrust force increases rapidly with feed rate increase, especially at the highest spindle speed of 2400 rpm, with a drill of 10 mm (Figure 4c).…”

“…They observed that the thrust force created with the standard drill tool is significantly bigger than that obtained with the trepanning tool. Maleki et al [7] carried out an investigation on the machining of woven jute fabric reinforced polymer composite with different drill tool materials. They [7] showed that the delamination factor and thrust force are lower with the HSS drill compared to those obtained with carbide drills (CoroDrill 854 and CoroDrill 856).…”

“…The surface roughness generated with the CoroDrill 856 was higher than that made with the HSS tool and the carbide CoroDrill 854. They recommended using the HSS twist drill when drilling jute fiber reinforced polymer composites [7].…”
