Composite Engineer Interview Questions and Answers

The best material for tooling development is typically epoxy resin due to its high strength, durability, and dimensional stability.

• Epoxy resin is commonly used for tooling development in composite manufacturing due to its high strength and durability.

• It has excellent dimensional stability, which is crucial for maintaining the shape and accuracy of the tool over time.

• Epoxy resin can also be easily machined and polished to achieve the desired surface finish for the tool.

Composite failure can be identified through visual inspection, non-destructive testing, and mechanical testing.

• Visual inspection: Look for cracks, delamination, or other visible signs of damage on the surface of the composite material.

• Non-destructive testing: Use techniques like ultrasonic testing, thermography, or radiography to detect internal defects without damaging the material.

• Mechanical testing: Conduct tests such as tensile, compression, or flexural testing to assess ...read more

Stacking sequence in composites refers to the specific order in which different layers of materials are stacked together to form a composite structure.

• Stacking sequence determines the orientation of each layer's fibers or reinforcement materials.

• The sequence can greatly impact the mechanical properties of the composite, such as strength, stiffness, and impact resistance.

• Common stacking sequences include unidirectional, quasi-isotropic, and angle-ply laminates.

• For example, a s...read more

Monolithic process refers to a manufacturing process where a product is made in a single continuous step.

• Involves creating a product in one continuous process without any breaks or interruptions

• Typically used in industries like semiconductor manufacturing and composite materials production

• Results in a product with uniform properties and characteristics
