(Key: C=Poor, B=Good, A=Excellent)

Aramid

• High strength, good impact, high abrasion resistance and medium stiffness.

Carbon

• Very high strength in both tensile and compression, high stiffness and high resistance to corrosion, creep and fatigue. But poor impact strength.

Glass

• Good compressive strength and stiffness, good tensile strength and excellent electrical properties at relatively low cost.
