Preview Questions Composite Technician | Role Specific Skill

Question 1: What is the significance of "Thick Laminate Manufacturing" in aerospace composites, and how does it affect performance?

Which action should you take?

Choose only one option

Thick laminate manufacturing provides the necessary strength and stiffness for high-stress components like aircraft wings

Thick laminates add unnecessary weight to the aerospace structure

It reduces manufacturing time but compromises composite strength

Thick laminates are used only for decorative applications

Question 2: How does fiber orientation affect the mechanical properties of composite materials used in aerospace applications?

Which action should you take?

Choose only one option

Fibers should be oriented only for visual appeal

The orientation of the fibers directly influences the material's strength in specific directions

Random fiber orientation improves the material's isotropic properties

Fiber orientation does not significantly affect the properties

Question 3: How do "Static Electricity" and "Grounding" contribute to safety when working with composite materials and chemicals in aerospace?

Which action should you take?

Choose only one option

Grounding is only necessary when working with metallic components

Proper grounding prevents static build-up, which can cause sparks and ignite volatile chemicals, ensuring a safer work environment

Static electricity has no impact on composite work, as resins are non-reactive

Grounding is unnecessary as long as PPE is used

Question 4: In composite manufacturing, what is the primary purpose of vacuum bagging?

Which action should you take?

Choose only one option

To remove air and excess resin, ensuring optimal fiber consolidation and minimal voids

To improve the aesthetic finish of the composite surface

To speed up the curing process by increasing temperature

To add additional resin for extra strength

Question 5: In the aerospace composite manufacturing process, what is the key benefit of using prepreg materials?

Which action should you take?

Choose only one option

Prepregs provide precise resin-to-fiber ratio and eliminate the need for resin mixing

Prepregs are easier to handle than dry fibers

Prepregs reduce the curing time significantly

Prepregs are more affordable compared to wet-lay composites

Question 6: What are the main concerns when "Repairing Cracks" in composite structures, and how should they be addressed?

Which action should you take?

Choose only one option

Cracks should be left unaddressed as they do not affect the overall integrity

Cracks need to be repaired by removing damaged material, properly bonding new layers, and ensuring structural integrity

Cracks can be filled with resin without the need for fiber reinforcement

Cracks are only a cosmetic issue and do not need to be repaired
