Introduction: Since the first aircraft was developed for flight, people have had a goal to improve the aircraft’s physical applications and production of the aircraft more profitable. These changes made aircraft lighter and have increase flight ranges for aircraft for useful for people. In aircraft modification in today’s world is making another major leap in attempting to replace metal structures on aircraft. The reasons for the changes are due to production cost, to create a lighter aircraft, to increase load capabilities, and aim to prevent fatigue and corrosion damage. New structures are being developed to replace metal parts happen to be composite parts. Composite (ex: CTRP) parts are able to meet the standards required to replace metal parts. Due to the new requirements the aircraft will be operated for a longer amount of time until being replaced thus the aircraft structure has a longer lifetime. This seems to be a solution until looking at the engineering aspect of the composite replacing a metal. The reality is that metals and composites not the same structure. Every design aspect has to be corrected therefore the composite can function identically as a metal would in flight. Another issue is that the composites when manufactured need to be checked for issues such as voids, porosity, and fiber misalignment which will cause the composite to fail when it should function right. Even with the production issues with composites structures, composites still have…
