Which of the following are generally characteristic of carbon/graphite fiber composites? 1. flexibility.2. stiffness.3. high compressive strength.4. corrosive effect in contact with aluminum.5. ability to conduct electricity. a. 1 and 3b. 2,3 and 4.c. 1,3, and 5.

option B

Explanation:

The correct answer is option B

Carbon/graphite fiber composite is a polymer composite which is five times stronger than the mild steel and five-time more lighter than it.

This material has a high-temperature resistant quality, it works as a high insulator. The material does not melt at high temperatures. And the material is also corrosive resistant but has a corrosive effect when contact with aluminum.

Hence, we can say that Carbon/graphite fiber has high stiffness, high compressive strength, and have a corrosive effect in contact with aluminum.
