In-plane adhesively bonded joints in sandwich structures

Abstract

This work is concerned with the mechanical behaviour of in-plane joints in sandwich structures under static flexural loads. The impetus behind research into these joints stems from the growing development in modular construction techniques that offer competitive global access to higher technology sandwich structures. Characterisation of flexural response is therefore important, as in most instances the primary role of a sandwich is to impart flexural rigidity. A test program involving several commonly used joining methods, including scarf, internal spline and external tape, coupled with flexible and inflexible adhesives were used to demonstrate the mode of failure, strength and stiffness of the joined sandwich. Adaptation of an existing strain measurement technique to the sandwich offers the ability to quantify the joint as a unit, allowing the engineer to conceptualise its performance as a weld. Analytical approaches, together with a numerical study, are used to provide more general comment on optimum in-plane scarf joint configurations. The results are discussed in light of practical ship and boat construction applications, but are directly relevant to large sandwich constructions in general.
