Carbon fiber reinforced polymers (CFRP) are stronger and lighter materials in the aerospace industry, instead of titanium and aluminum. The excellent strength-to-weight and stiffness-to-weight properties of composite materials are the main drives of increasing the ratio of the composite parts in aircraft. Less weight on aircraft means less amount of fuel consumption. Subsequently, aircraft can able to fly longer range with higher speeds and more efficiently. As a result, it is a more economical and environmentally friendly condition, which gives the product value and competitiveness for the aircraft manufacturer. During CFRP laminate joining manufacturing activities, delamination is one of the major forms of failure in drilled materials. In this research, a comparative study of drilled hole quality after drilling without pre-hole and pre-hole with three different diameters on CFRP has been made. Two types of different geometrical drill bits were used for the drilling process. The ultrasonic scan images were taken into account to determine the surface delamination. [ABSTRACT FROM AUTHOR] |
