Chapter 17, Problem 17.55P
Interpretation Introduction

Interpretation:

Modulus of elasticity of composite for parallel and perpendicular condition should be determined.

Concept introduction:

Modulus of elasticity is defined as the ratio of shear stress to shear strain.

Relation for modulus of elasticity is given as:

  EC=fglassEglass+fpolymerEpolymer

  fglassEglass are the volume fraction and modulus of elasticity for glass.

  fpolymerEpolymer are the volume fraction and modulus of elasticity for polymer.

  f=V1V1+V2f=volumefractionV1=volumeoffirstcomponentV2=volumeofsecondcomponent

Relation for modulus of elasticity perpendicular to fiber is given as:

  1EC=fglassEglass+fpolymerEpolymer

  fglassEglass are the volume fraction and modulus of elasticity for glass.

  fpolymerEpolymer are the volume fraction and modulus of elasticity for polymer.

  f=V1V1+V2f=volumefractionV1=volumeoffirstcomponentV2=volumeofsecondcomponent
