Preview Questions Composite Technician | Role Specific Skill

Question 1: In composite materials, what is the significance of the "Fiber Orientation" when laying up the material for aerospace applications?

Which action should you take?

Choose only one option

Fiber orientation impacts only the aesthetic appearance, not the strength

Fiber orientation only affects the bonding process, not the mechanical properties

Fiber orientation affects the strength, stiffness, and load-bearing capacity of the composite in specific directions

Fiber orientation is irrelevant as long as the fibers are tightly packed

Question 2: Which of the following testing methods is most useful for detecting voids in composite materials used in aerospace applications?

Which action should you take?

Choose only one option

X-ray computed tomography (CT)

Optical microscopy

Ultrasonic testing

Dynamic mechanical analysis (DMA)

Question 3: What is the role of prepreg materials in composite manufacturing for aerospace?

Which action should you take?

Choose only one option

To reduce the curing time and temperature

Pre-impregnated fibers that eliminate the need for separate resin application and ensure uniform resin content

To improve the strength of the resin used in composites

To create lightweight materials with no reinforcement

Question 4: What is the primary concern when using composites in high-temperature aerospace applications?

Which action should you take?

Choose only one option

The weight of the composite material in high-temperature environments

The ability of the composite to absorb heat without structural failure

The cost-effectiveness of the composite material

The thermal stability of the matrix material and the possibility of resin degradation

Question 5: What are the primary factors to consider when selecting the "Curing Cycle" for composites in aerospace manufacturing?

Which action should you take?

Choose only one option

Temperature, pressure, and time must be optimized to ensure proper curing and avoid defects

Only temperature needs to be controlled, as pressure and time are secondary

Curing cycles should be short to reduce manufacturing time

Pressure is not important as long as time and temperature are correct

Question 6: What is the primary role of resin in composite materials used in aerospace?

Which action should you take?

Choose only one option

To increase the thermal conductivity of the composite

To decrease the overall weight of the composite

To bond the fibers together, provide shape, and resist environmental damage

To increase the material's density for better durability
