Question 1: In aerospace material development, what is the significance of using a thermogravimetric analysis (TGA)?

Which action should you take?

Choose only one option

To assess the material's thermal stability and weight loss under heat

To evaluate the material's impact resistance

To measure the hardness of the material

To determine the material's corrosion rate

Question 2: What is the primary challenge of using "Thermoplastic Composites" in aerospace, and how do they compare to thermosetting composites?

Which action should you take?

Choose only one option

Thermoplastic composites are always superior to thermosetting composites

Thermosetting composites are more expensive but less efficient than thermoplastic composites

Thermoplastic composites are too brittle for aerospace use

Thermoplastic composites offer easier repairability and faster manufacturing cycles, but they are typically less heat-resistant than thermosetting composites

Question 3: What is the importance of "Material Microstructure" in determining the mechanical properties of aerospace alloys?

Which action should you take?

Choose only one option

The microstructure defines the strength, toughness, and ductility of materials, which are critical for structural integrity

Microstructure has no impact on material properties in aerospace

Microstructure is only important for composite materials, not metals

Microstructure is irrelevant in materials used for high-pressure components
