Chirped fibre Bragg grating (CFBG) sensors have been embedded within the adhesive bondline of single-lap bonded composite joints, fabricated using a transparent glass fibre reinforced plastic (GFRP) adherend bonded to a carbon fibre reinforced plastic (CFRP) adherend. During fatigue cycling, disbonds initiated adjacent to the cut ends of one, or both, of the adherends and the disbonds propagate...

In this work, the effect of adherend shape on the tensile strength of adhesively bonded single lap aluminum structures joint was numerically studied using three dimensional finite element models. Six joint models were investigated. In this paper, a static finite element analysis was performed in A...

Environmental, political. and socioeconomic actions over the past several years have resulted in a decreased wood supply at a time when there is an increased demand for forest products. This combination of increased demand and decreased supply has forced more emphasis on engineered wood products, a varied category usually connected with adhesively-bonded end joints, of which the most common typ...

 provision of large, stress-bearing area  excellent fatigue strength  good shock absorption  reduced galvanic corrosion  no need to have access to far-side of adherend to make joint  bonding is possible on dissimilar materials  provision of smooth contours and sections around joint areas  sealing  improved damping which increases structural stiffness  reduction in distortion and metal...

Preeious metal alloys bondcd by the adhesive r'esin were thermocycled O, 1,OOO, 2,OOO, or 4,OOO times in water between 4 and 60°C , and tensile bend strengths were measurecl. Debonded metal surfaces after the tensile test were analyzed based on an area of cohcsive failure. Three-way ANOVA revealed that all the three parameters adherend, adhesive rnonemer, and nurnber of thermal cycles exhibited...

This paper addresses the sensitivity of ultrasonic welding process for joining dissimilar composites to variations in either force or amplitude vibrations. For that, carbon fibre (CF)/epoxy specimens were welded CF/polyetheretherketone (PEEK) specimens, through a polyetheretherimide (PEI) coupling layer co-cured with CF/epoxy material. It was found that reducing vibrations caused an increase he...

In aerospace and many types of civil infrastructure applications, the use of adhesive-bonded composite joints have been constantly increasing. In this study, fracture behaviour of adhesively bonded single lap joint (SLJ) with pre-existing damage at the interface of free edge of the top adherend and adhesive along the width of the joint is studied by strain energy release rate (SERR) approach us...

Recent work has outlined a method for health monitoring the structural integrity of adhesively bonded composite joints based on the use of a chirped fibre Bragg grating (CFBG) embedded within an adherend, but not within the glue-line. In this paper, the reflected CFBG spectra for disbonds of different lengths have been predicted with the aid of a finite-element model of the strain field resulti...
