Question
Chapter 12, Problem 1CQ
To determine
The quantity which is equal in both matrix and reinforcing phase when a force is applied parallel to a reinforcing phase of a composite material.
Expert Solution & Answer
Answer to Problem 1CQ
Thestrainis equal in both matrix and reinforcing phase when a force is applied parallel to a reinforcing phase of a composite material.
Explanation of Solution
The composite material is a combination of two or more materials together to reinforce the properties of base material. In a composite material the matrix phase is reinforced or surrounded by second phase to provide unique properties like conductivity, strength, wear resistance etc. to composite.
When a force is applied to a reinforced phase, a strain developed in both the matrix and reinforcing phase. The developed strain is considered to be equal in magnitude for both the matrix and reinforce material.
When a force is applied to the reinforced phase, due to the stress developed, the material with very low strain to fracture will fails first. The failure is due to the fact that the phases of composite material would have same strain.
Conclusion:
Thus, thestrainis equal in both matrix and reinforcing phase when a force is applied parallel to a reinforcing phase of a composite material.
