Preview Questions Composite Technician | Role Specific Skill

Question 1: What is the role of "Vacuum Bagging" in composite repair for aerospace applications?

Which action should you take?

Choose only one option

It ensures proper resin distribution and consolidation of the repair material, removing air voids and enhancing bond strength

It makes the composite repair process faster but less durable

It is only used for aesthetic repairs and not structural ones

It reduces the weight of the repaired composite material

Question 2: What is the benefit of using dynamic mechanical analysis (DMA) in composite material testing?

Which action should you take?

Choose only one option

To determine the overall strength and rigidity of the composite

To measure the chemical composition of the matrix material

To test the material's impact resistance

To evaluate the material's viscoelastic properties, including its response to temperature changes

Question 3: How should a Composite Technician address a situation where there is insufficient resin penetration in a repair area?

Which action should you take?

Choose only one option

Reapply resin under vacuum or pressure to ensure thorough wetting and impregnation of fibers

Ignore the issue and proceed with the repair process

Add more resin without considering proper curing pressure

Only apply resin to the surface and skip further penetration checks

Question 4: What type of fiber is most commonly used in aerospace composites for its high strength-to-weight ratio?

Which action should you take?

Choose only one option

Glass fiber

Aramid fiber

Basalt fiber

Carbon fiber

Question 5: What is the correct safety procedure for handling compressed air tools during composite manufacturing?

Which action should you take?

Choose only one option

Skip the safety checks if the tools are working fine

Allow others to operate tools without training or supervision

Use the tools without safety covers or guards

Always ensure that tools are properly secured and PPE is used, particularly eye and ear protection

Question 6: How does moisture absorption affect composite materials used in aerospace applications?

Which action should you take?

Choose only one option

It increases the weight of the composite without affecting strength

It can reduce the mechanical properties and cause delamination

It enhances the bonding properties of the resin

It does not have any significant impact on composite properties
