Preview Questions Composite Technician | Role Specific Skill

Question 1: What does "Delamination Testing" in composites aim to identify, and why is it critical for aerospace applications?

Which action should you take?

Choose only one option

It evaluates the weight reduction capability of composite materials

It identifies the separation of composite layers under stress, which can compromise the structural integrity and safety of aerospace components

It measures the resin flow during the curing process

It checks for surface smoothness and aesthetic qualities of composites

Question 2: 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 3: What type of damage mechanism is most commonly associated with composite materials under high-impact conditions?

Which action should you take?

Choose only one option

Matrix cracking and fiber delamination

Minor surface deformation with no structural impact

Surface scratching and adhesive wear

Thermal degradation and corrosion

Question 4: How should a Composite Technician approach the repair of composite parts that have been exposed to impact damage?

Which action should you take?

Choose only one option

Focus on cosmetic repairs and ignore the impact on structural integrity

Use excess adhesive to bond the damaged area without reinforcing the structure

Assess the extent of damage, remove the damaged area, and restore the part with appropriate fiber orientation and resin

Apply a patch over the damaged area without assessing the internal structure

Question 5: In composite repairs, why is it important to ensure that surfaces are free from contaminants like oil, dirt, and moisture?

Which action should you take?

Choose only one option

Contaminants can interfere with bonding and reduce the strength of the repair

Contaminants enhance the resin flow and improve the bond

Contaminants can speed up the curing process

Contaminants help improve the material's flexibility

Question 6: Why is "Thermal Cycling" an important test for composites used in aerospace applications?

Which action should you take?

Choose only one option

It tests the material's resistance to impact during high-speed flight

It evaluates the material's resistance to long-term wear and abrasion

It measures the material's elasticity under different loading conditions

It simulates the material's performance under extreme temperature variations, evaluating its stability and resistance to thermal stresses
