1. In the figures shown below the same force is applied to a composite that is reinforced with fibers running in different directions. A B a. Which composite deforms the least? Why? (3 pts) C D b. Assume the critical fiber length is ~ 4.5 mm and the fiber diameter is ~ 6.0 mm. You have a choice between fibers with lengths of 0.75 mm and fibers with lengths of 75.0 mm, which would provide the most efficient reinforcement? Explain your answer. (4 pts) C. List and briefly define the roles of the phases of composite materials. (3 pts)
