What can go wrong in quality control? How are aerospace materials quality controlled?

3

Aerospace Materials Quality Control

Quality Control is conducted by a team…

– Design engineer– Materials engineer– Stress engineer– Raw materials producer– Production Planner– Technician– Quality Assurance Inspector

4

Aerospace Materials Quality Control Team

Design engineer- responsible for the general design of the aircraft performance, and general concept. All of which must be met with available materials and manufacturing processes.

5

Aerospace Materials Quality Control Team

Materials engineer- specifies the materials based on properties, cost, size, shape, processing etc.

6

Aerospace Materials Quality Control Team

Stress engineer- analyzes/refines geometry to ensure the material of the components are not pushed beyond their properties.

7

Aerospace Materials Quality Control Team

Raw materials producer- supplies the materials for the aircraft, maintains quality control of physical properties, identifies material and produces certifications to accompany material, may package materials to protect from environmental damage before use. The materials producer may frequently test the material or send samples for independent verification.
