Describe a time when you had to troubleshoot and resolve manufacturing issues related to composite materials.

During my previous internship at a composite materials manufacturer, I encountered a manufacturing issue related to delamination in a carbon fiber composite part. The issue was causing the part to fail under load. I quickly identified the root cause by conducting non-destructive testing using ultrasonic techniques. The tests revealed an inconsistency in the resin distribution, leading to the delamination. To resolve the issue, I worked closely with the production team to adjust the resin infusion process parameters and improve the vacuum bagging technique. I also performed additional testing to verify the effectiveness of the changes. As a result, we successfully eliminated the delamination issue and improved the part's structural integrity.

During my previous internship at a composite materials manufacturer, I faced a challenging manufacturing issue with a carbon fiber composite part. The part was experiencing delamination, leading to structural integrity concerns. To troubleshoot the issue, I conducted a thorough analysis using non-destructive testing techniques such as ultrasonic testing. The testing revealed that the delamination was caused by an inconsistency in the resin distribution during the manufacturing process. To address the issue, I collaborated with the production team to adjust the resin infusion parameters and optimize the vacuum bagging technique. Additionally, I conducted further testing to verify the effectiveness of the changes. Through these efforts, we successfully resolved the delamination issue and improved the part's performance and reliability. This experience enhanced my technical proficiency in composite materials and strengthened my problem-solving skills.

During my previous internship at a composite materials manufacturer, I encountered a complex manufacturing issue involving buckling and warping in a composite structure. The issue was affecting the dimensional stability and overall performance of the part. To investigate the problem, I utilized advanced finite element analysis (FEA) software to simulate the structural behavior and identify potential design flaws. Through the analysis, I discovered that the issue was caused by inadequate reinforcement in certain areas, resulting in localized stress concentrations. I worked closely with the design engineering team to develop a modified design that incorporated additional reinforcement in critical regions. To validate the design, I conducted physical testing using an environmental chamber to mimic real-world conditions. The tests confirmed a significant improvement in dimensional stability and addressed the buckling and warping concerns. The successful resolution of this complex manufacturing issue showcased my technical proficiency in composite materials, problem-solving and analytical skills, adaptability to new technologies, and effective collaboration with cross-functional teams.
