Preview Questions Composite Technician | Role Specific Skill

Question 1: Why is "Gel Coat Application" critical in composite manufacturing for aerospace, and how does it affect the final product?

Which action should you take?

Choose only one option

Gel coats reduce the strength of the composite and make it more brittle

Gel coats are only used for aesthetic purposes and do not affect performance

Gel coats provide a smooth, durable surface, protect the composite from environmental damage, and improve aesthetic appearance

Gel coats are optional and do not impact the quality of the final composite

Question 2: When evaluating the environmental resistance of composite materials, what is the primary concern in aerospace applications?

Which action should you take?

Choose only one option

Changes in material color due to weathering

Ultraviolet degradation and oxidation

Surface wear from frequent mechanical contact

Exposure to moisture and temperature cycling

Question 3: What is the primary challenge in repairing aerospace composite parts that are exposed to high temperatures?

Which action should you take?

Choose only one option

Selecting repair materials that can withstand the elevated temperature environment without degradation

Ignoring the temperature conditions and using standard materials

Focusing solely on surface repairs without considering structural integrity

Using low-temperature resin systems that do not provide adequate bonding

Question 4: When performing a resin flow test during composite fabrication, what is being measured?

Which action should you take?

Choose only one option

The tensile strength of the resin used in the composite material

The resin's chemical resistance to environmental factors

The bonding strength of the resin to the fibers

The ability of the resin to flow and penetrate through the fibers during the layup process

Question 5: When using a pre-preg composite material in aerospace manufacturing, why is it critical to maintain a specific temperature during storage?

Which action should you take?

Choose only one option

To increase the resin's viscosity for better handling

To reduce the fiber's tensile strength

To prevent the resin from prematurely curing and becoming unusable

To prevent the material from becoming brittle over time

Question 6: How does temperature affect the curing process of composite materials?

Which action should you take?

Choose only one option

Very high temperatures can cause the resin to become brittle

High temperatures accelerate the curing process, but can lead to fiber degradation if not controlled

Low temperatures can shorten curing time

Temperature has no significant impact on curing
