Certified Composites Technicians (CCTs) are responsible for fabricating, inspecting, and repairing composite structures in various industries, including aerospace, automotive, and marine. They work with high-performance materials such as carbon fiber, fiberglass, and epoxy resins.

1. Fabrication

CCTs fabricate composite parts by following detailed engineering drawings and specifications. They use various techniques such as hand layup, vacuum bagging, and autoclave curing to create complex shapes and structures.

• Interpret engineering drawings and specifications to determine material selection and fabrication methods.
• Lay up composite materials using hand layup, vacuum bagging, or autoclave curing techniques.
• Inspect fabricated parts for quality and conformance to specifications.

2. Inspection

CCTs inspect composite structures using non-destructive testing (NDT) methods such as ultrasonic, X-ray, and thermography to identify defects and ensure structural integrity.

• Perform NDT inspections to identify defects in composite structures.
• Interpret NDT results and make recommendations for repairs or corrective actions.
• Maintain inspection records and documentation.

3. Repair

CCTs repair damaged composite structures using techniques such as patching, bonding, and reinforcement. They ensure that repaired structures meet original design specifications and safety standards.

• Identify and assess damage to composite structures.
• Develop and implement repair plans based on damage assessment.
• Perform repairs using approved techniques and materials.

4. Quality Assurance

CCTs play a critical role in maintaining quality assurance in composite fabrication and repair. They adhere to industry standards and regulations to ensure the safety and reliability of composite structures.

• Monitor and maintain quality control procedures throughout the fabrication and repair process.
