Abstract

Drilling makes holes in aircraft components that aim to unite other structural parts to create a robust and reliable structure. The drilling process on composite materials does not always work well, resulting in the composite being damaged during the drilling process. One punching defect is delamination (a measure of the damaged area around the hole). This study focused on the composite materials used in aircraft, namely carbon fiber composites with an epoxy resin matrix. The drilling treatment method is directly or in stages and combine them with drilling parameters such as cutting speed and feed rate. The drilling treatment on the entry surface produces a value of F > F crit with a value of 10.3477 > 4.171 based on the hypothesis test using the F distribution that the P-value is 0.003 < 0.05. then the exit surface drilling produces a value of F > F crit with a value of 5.4797 > 4.171 based on the hypothesis test using the F distribution that the P-value is 0.02 < 0.05. Drilling treatment was reinforced by ANOVA calculations with the results that the P value on the entry and exit surface was less than 0.05, indicating that the drilling treatment affected the delamination results. 1.1983 and 1.2487, respectively. The highest levels of delamination occurred at the entry and exit surfaces at RPM 3500 by direct drilling with values of 1.3328 and 1.3827, respectively. With this result, the higher the RPM value, the resulting delamination effect increases both direct and gradual drilling.
