In the current study, the effect of the thickness and the foam density in three-dimensional integrated woven sandwich
composites on quasi-static properties was investigated. For this purpose, produced samples were subjected to uniaxial
flatwise compression tests and their compression strength and moduli were determined. Obtained results were
optimized by taking core thickness, foam density and panel weights into consideration. Damages that occurred on
the tested samples were reported. When compared to conventional foam core sandwich composites, it was found
that three-dimensional integrated sandwich composites have better compression properties and due to the fact that the
pile yarns in the core and the foam support each other.
