Experimental study of drilling glass fiber reinforced plastics (GFRP) manufactured by hand lay-up

Experimental investigation on delamination in nanocomposite drilling

“…Several empirical studies have been performed to understand the effects of drilling parameters on drilling thrust force and associated delamination. Almost all researchers reported that feed rate makes the largest contribution to delamination and thrust force and both increase with feed rate at any cutting speeds [28][29][30][31][32][33][34][35][36][37]. The effect of cutting speed is contradictory, since increasing this parameter was reported beneficial in references [38][39][40], while it did affect negatively delamination in references [41][42][43][44].…”

Evaluation of Thrust force in Drilling Woven roving Glass fibre reinforced Aluminium Sandwich laminates with TiAlN coated drill using Taguchi analysis

“…The result proved that spur geometry of cemented carbide drill exhibited less thrust force compared with 118º point angle. From ANOVA data analysis it is proved that cutting pressure gets reduced with increasing penetration speed and it becomes highest significant factor among the other factors considered to affect both the cutting pressure and thrust force developed during drilling [8]. Basavarajappaa et al discussed the effect of spindle speed, feed rate on feed force developed in drilling hybrid metal matrix composites, the composite is made by stir casting, The effect of these cutting parameters on burr height and surface finish is also studied, the Taguchi analysis is employed to analyse the datas and it is revealed that the output is greatly influenced by the feed rate that the speed [9] Many adverse damages like delamination, fibre pull outs produced during drilling reduce the fatigue strength of composite laminates thereby reducing its durability.…”

Characterization of jute and glass fiber reinforced polyester based hybrid composite In this research

“…For the synthesis of composite there are many techniques available in industries such as compression molding, vacuum molding, pultruding, hand lay-up and resin transfer molding. Out of all the hand lay-up process is most popular technique because it is a simple and easy method to follow to fabricate composite (Davim et al, 2014). The hand lay-up technique facilitates fabrication of very large and complex composite with minimum manufacture time.…”
