Preview Questions Composite Technician | Role Specific Skill

Question 1: How does "Structural Reinforcement" work in composite repairs, and when is it necessary in aerospace applications?

Which action should you take?

Choose only one option

Structural reinforcement is unnecessary as long as the resin is applied evenly

Structural reinforcement, such as using additional layers or patches, is needed for areas subjected to high stress or load

Structural reinforcement is only used for aesthetic purposes, not strength

Structural reinforcement weakens the composite, making it less durable

Question 2: How does moisture absorption affect the properties of composite materials in aerospace applications?

Which action should you take?

Choose only one option

It increases the thermal resistance of the composite material

It can lead to a reduction in mechanical properties such as strength and stiffness

It has no impact on composite properties in aerospace use

It enhances the material's resistance to fatigue and cracking

Question 3: 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 4: In aerospace composite manufacturing, what is the significance of "Fiber Volume Fraction" (FVF), and how does it impact the final product?

Which action should you take?

Choose only one option

FVF affects only the cosmetic appearance of the composite, not its structural integrity

FVF only impacts the curing process and not the composite's mechanical properties

FVF is irrelevant as long as the resin content is correct

FVF determines the amount of fiber in the composite, affecting its strength, stiffness, and weight

Question 5: In composite material testing, what does an interlaminar shear test evaluate?

Which action should you take?

Choose only one option

The impact resistance of the outermost layers of the composite

The ability of the resin to bond with the fibers at elevated temperatures

The shear strength between the layers of a laminated composite material

The flexural strength of the composite material

Question 6: What is the most significant challenge associated with the out-of-autoclave (OOA) processing method in composite material manufacturing?

Which action should you take?

Choose only one option

Reducing the weight of composite parts

Ensuring uniform heat distribution in the absence of autoclave pressure

Managing the increased costs due to specialized equipment

Achieving the same high-quality results without using an autoclave
