DISADVANTAGES

Fatigue is affected badly from the grains of air in thecomposite material.

Composite materials have different properties in differentdirections in the material

Tensile strength, discharge voltage, flexural strength may bedifferent for the same composite material

Precision manufacturing like hole drilling or cutting can notbe applied to composite materials because they may cause

openings in fibers
