Preview Questions Composite Technician | Role Specific Skill

Question 1: In resin transfer molding (RTM), what is the function of the mold's pressure during the infusion process?

Which action should you take?

Choose only one option

To reduce the thickness of the composite material

To compress the material and eliminate air gaps or voids

To facilitate the mixing of resin with the fibers

To accelerate the curing process

Question 2: How should a composite technician address a surface that has been scratched or damaged on an aircraft composite part?

Which action should you take?

Choose only one option

By sanding the damaged area to achieve a smooth surface and reapplying the resin

By replacing the entire composite panel

By ignoring the damage and applying a protective coating

By applying a new layer of composite without surface preparation

Question 3: What is the key difference between wet layup and dry layup techniques in composite manufacturing?

Which action should you take?

Choose only one option

Wet layup is used exclusively for structural parts, and dry layup for non-structural parts

Wet layup involves pre-impregnated fibers, and dry layup uses only resin

Wet layup uses liquid resin applied directly to the fibers, while dry layup uses pre-impregnated fibers

Dry layup involves manual curing, while wet layup uses an autoclave

Question 4: What is the most effective method to evaluate the tensile strength of composite materials used in aerospace applications?

Which action should you take?

Choose only one option

Conducting a thermal test to assess the material's stability

Conducting a tensile test to measure force and elongation

Performing a flexural test to determine bending resistance

Using a fatigue test to simulate long-term stress

Question 5: In composite material handling, what is the key safety consideration when using a high-temperature curing process?

Which action should you take?

Choose only one option

Overheating the resin to speed up the curing process

Proper protective equipment such as heat-resistant gloves and ensuring correct temperature settings to avoid burns

Relying on ventilation alone without considering temperature risks

Ensuring that the curing process is completed quickly to minimize exposure

Question 6: What safety precaution should be followed when working with autoclaves in composite manufacturing?

Which action should you take?

Choose only one option

Use the autoclave without safety checks, relying on automated controls to manage risks

Open the autoclave immediately after the cycle to prevent cooling issues

Ignore temperature limits to save time on curing

Ensure that the autoclave is properly calibrated, and follow the manufacturer's safety guidelines for pressure and temperature settings
