Which of the following are generally characteristic of aramid fibre (Kevlar) composites?
- High tensile strength and flexibility.
- Flexibility, stiffness and corrosive effect in contact with aluminium.
- High tensile strength, stiffness and ability to insulate electricity.
Explanation from PART66Online
Aramid (Kevlar) fibres combine very high tensile strength with stiffness and good impact/damage tolerance, and being a polymer they are electrical insulators rather than conductors. Unlike carbon fibre they do not cause galvanic corrosion of aluminium, so options pairing aramid with a corrosive effect or with electrical conductivity are wrong.

Sure, there should be insulate, not conduct. I corrected this question, thanks.
