For some glass fiber-epoxy matrix combination, the critical fiber length-fiber diameter ratio is 33.2. Determine the fiber-matrix bond strength. Assume that the tensile strength for glass is 3.45 GPa (0.5 × 106 psi).

The fiber-matrix bond strength is [b] 51.96MPa [/b]

Explanation:

We are given:

We take d=1

Therefore, to find the fiber-matrix bond strength we use the formula:

;

substituting figures in the equation, we have:

= 33450 * 0.015

= 51.96 MPa

Therefore the fiber-matrix bond strength is 51.96MPa

Fiber-matrix bond strength = 51.96 MPa

Explanation:

To calculate: Fiber-matrix bond strength

Critical fiber length diameter ratio,

Therefore,

Tensile strength for glass,
