The image above shows a fiber fabrication process.
Which fiber type is this process referring to?

• Carbon fiber

• Glass fiber

Sandwich composites' core typically fall into three categories, which of the following is not:

• Polymeric foam

• Wood

• Honeycomb

Aligned fibrous composites are inherently

• Anisotropic

Type of weave shown in the image

• Unidirectional

• Satin weave

• Twill weave

• Plain weave

Consider the elastic behavior of a continuous and oriented fibrous composite that is loaded in the direction of fiber alignment, were deformation of both matrix and fibers is the same. That means:

• Isostrain situation

• Isostress situation

What is this formula used for?

• Composite longitudinal load

• Critical fiber length

• Critical fiber load

It is composed of several two-dimensional sheets or panels that have a preferred high-strength direction.

• Core

• Honeycomb

• Laminate

• Sandwich composite

What is this equation used for?

• Composite modulus of elasticity in longitudinal direction

• Fiber modulus of elasticity in longitudinal direction

• Composite modulus of elasticity in transversal direction

• Fiber modulus of elasticity in transversal direction

What is this equation used for?
