Modeling of the mechanical behavior of composite at different relative humidities
The moisture diffusion and mechanical response in shear of a laminate constituted of 12 layers of glass fabric fiber/epoxy resin were evaluated. The experimental analysis of the moisture absorption of the specimens conditioned at different relative humidities, 0, 60, and 96% RH at 60°C was to...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The moisture diffusion and mechanical response
in shear of a laminate constituted of
12 layers of glass fabric fiber/epoxy resin
were evaluated. The experimental analysis
of the moisture absorption of the specimens
conditioned at different relative humidities,
0, 60, and 96% RH at 60°C was to determine
the two parameters characteristic of the Fick
diffusion law (the diffusion coefficient D
and the maximum quantity of water of saturation
Mm) which admits the reversibility of
the phenomenon. The analysis of the mechanical
response in shear of the specimens
oriented at 45° tested in uniaxial tension at
constant imposed displacement rates, has
permitted to show that the influence of the
moisture concentration for the composite is very important at 96% RH. The proposed simple
model permits to specify the influence of water
absorption on the mechanical behavior in shear. |
