Experimental analysis of behavior and damage of sandwich composite materials in three-point bending. Part 1. Static tests and stiffness degradation at failure studies
The analysis of stiffness and the identification of rupture mechanisms during and after static tests of sandwich panels and their components have been investigated. The sandwich panels, having cross-ply laminates skins made of glass fibre and epoxy resin were manufactured by vacuum moulding an...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The analysis of stiffness and the identification
of rupture mechanisms during and after static
tests of sandwich panels and their components
have been investigated. The sandwich panels,
having cross-ply laminates skins made of glass
fibre and epoxy resin were manufactured by
vacuum moulding and subjected to three-point
bending tests. Two PVC cores of similar type
but with differing densities were investigated.
The effect of core density and its thickness on
the behavior and the damage was highlighted.
In terms of stiffness and load at failure, the
sandwich structure has better mechanical
characteristics compared to its components. |
