Strength Prediction of Adhesively-bonded Scarf Repairs in Composite Structures under Bending
This work reports on the experimental and numerical study of the bending behaviour of two-dimensional adhesively-bonded scarf repairs of carbon-epoxy laminates, bonded with the ductile adhesive Araldite 2015. Scarf angles varying from 2 to 45o were tested. The experimental work performed was used to validate a numerical Finite Element analysis using ABAQUS and a methodology developed by the aut...
متن کاملStrength of Composite Scarf Joints
In recent years, large composite structures have been used increasingly in the aerospace and naval industries. Such a large composite structure is mostly fabricated using the scarf joining technique so that multiple substructures can be connected together. Figure 1 shows three commonly used scarf joint configuration. Among the three, the step/overlap joint is considered as the strongest because...
متن کاملComputational Models of Adhesively Bonded Joints
Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of such adhesive bonding, there is an increasing need for effective and accurate computational methods. The geometry and the nature of an adhesive joint are, however, not so simple to describe effectively...
متن کاملA Probabilistic Method to Predict the Strength of Adhesively Bonded Joints of Gfrp
Experimental and numerical investigations were carried out on adhesively bonded full-scale double lap joints from pultruded GFRP profiles with relatively thick adhesive layers, needed in infrastructure applications to compensate for tolerances. The influence of different geometrical parameters on the joint strength was investigated, namely the thickness of the adhesive layer (from 5 to 35 mm), ...
متن کاملPropagation of ultrasonic Lamb waves in adhesively bonded lap joints
This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...
