Coefficients of Moisture Expansion

Coefficients of Moisture Expansion

Coefficients of Moisture Expansion

Coefficients of Moisture Expansion

Example Example 3.19 Find the two coefficients of moisture expansion for a Glass/Epoxy lamina with 70% fiber volume fraction. Use properties for glass and epoxy from Tables 3.1 and 3.2, respectively. Assume glass does not absorb moisture.

Example = 2500 kg/m3 = 0.3 = 1200 kg/m3 = 2110 kg/m3 = 0.33 m/m/kg/kg = 60.52 GPa = 3.4 GPa = 0.230
