Chapter 17, Problem 17.35P

Interpretation Introduction

Interpretation:

The strength of bond between fiber and matrix should be determined.

Concept introduction:

Relation gives critical length of fiber:

  $I_c=\frac{T_{Sf}d}{2{\tau }_i}$

Where,

  $T_{Sf}$ is the tensile strength of fiber

d is the diameter of fiber

  ${\tau }_i$ is the strength of bond between fiber and matrix

If critical length of fiber is known, then the value of strength between fiber and matrix can be calculated.
