and matrix
For a lamina exposed to changes in temperature, it is generally assumed that
(A) the change in temperature is the same
for the fiber and the matrix.
(B) the change in temperature is greater in
the fiber than in the matrix.
(C) the change in temperature is greater in
the matrix than in the fiber.
