Mechanical Behavior of Multimaterial Composite Systems. Interlaminar Behavior.

Abstract

A model of a multimaterial laminate (MML), consisting of orthotropic FRP and aluminum layers bonded through an interlaminar adhesive layer (IAL), was subjected to analytical and experimental investigation, the main aspect being the effect of IAL characteristics and boundary conditions on MML performance-especially on the delamination process which originates at the IAL edges. Analytical results, based on existing theories, yielded distribution functions for IAL shear and normal stresses, strains, forces and moments along the external structural layers (EAL) under mechanical and thermal loading. The EAL strain distribution and effect of edge restraint were verified in part by electrical and photoelastic measurements.
