Composite layups

CFRPs are laminates comprising the stacking of different layers of carbon fiber embedded in a polymer matrix, typically epoxy resin.

Material behaviour

Orthotropic

Quasi-isotropic

Anisotropic

Isotropic

Material that exhibit different resistance and stiffness depending on the direction of the material

Material that is isotropic only in a particular plane (within the same plane, its mechanical properties remain unchanged

Materials whose mechanical properties are unique in three mutually perpendicular directions

Material whose resistance and stiffness remain the same irrespective of the direction in which they are measured

Types of laminates

Hard laminates

Soft laminates

Most of their fibres oriented at either 45° or -45°

Most fibres oriented at 0°

Conventional VS contemporary layup

Plies of 0°, 90°, 45° and 45°

Double-double

QUAD

Set of 4 plys ±Φ±Ψ, where the values of Φ and Ψ range between 0° to 90

A great presentation...

• Improve communication on any topic
• Make a 'match' with your audience...
• And make them be part of the message
• Has an adequate color for its theme
• Represents data with graphics
• Uses timelines to tell stories

Audio

If your content is interactive, it’s engaging.

It is essential to check everything thoroughly. Don’t let any typos slip through!

The tone is usually formal and the vocabulary technical, so bear this in mind when drafting.
