Chp. 23: Carbon/Carbon Composites

Question 1

carbonization

Answer 1

atoms on a polymer chain other than carbon will be driven off by heat, leaving behind an amorphous carbon fiber with planes that lie parallel to the fiber length

Question 2

spinning

Answer 2

when a hot liquid pitch is placed in a container with a small hole, and a thin fiber is pulled from it.

Question 3

Carbon fibers are very____but not____.

Answer 3

very stiff but not strong

Question 4

specific modulus

Answer 4

Young’s modulus divided by the density

Question 5

Carbon Fiber Reinforced Plastic CFRP

Answer 5

when a carbon fibers are coated in a resin like epoxy where empty spaces are filled (impregnation)

Question 6

Answer 6

carbon fibers in a carbon matrix

Question 7

Answer 7

high temperatures up to 2500C
