Answer to Question 1

Aramid fibers are often used in applications where energy needs to be absorbed. Not forming strong bonds with the matrix allows slippage and friction heating between fiber and matrix and thus increases the amount of energy that is lost.

Answer to Question 2

Sizing agents are put on fibers to protect the fibers from mechanical damage during later processing, such as if the fibers are to be woven into a cloth. The coupling agents are placed on fibers to enhance the bonding between the fibers and the matrix.
