BOND STRENGTH EVALUATION IN ADHESIVE JOINTS USING NDE AND DIC METHODS
… defects and reliably predicting the bond shear strength. As a result, adhesive bonding technology is still not solely implemented in primary structures of an aircraft. Therefore, there is a greater demand for a novel NDE tool that can meet the existing aerospace requirement for adhesive …

Photoactivated Fixation of Cartilage Tissue
… as a parametric guide, in vitro mechanical testing of photochemically bonded meniscal fibrocartilage and hyaline articular cartilage tissues was performed using a modified single-lap shear test. Finally, the cellular viability and bond stability of a photochemically bonded cartilage …

Layer bonding of solvent-cast thin films for pharmaceutical solid dosage forms
… thin film layers was quantitatively measured by lap shear test. Based on this measurement, bonding threshold pressure was proposed as an indicator showing degree of bonding. At the same time, the layer bonding mechanism of solvent-cast thin films was interpreted as an interdiffusion of amorphous …

Manufacturing and Evaluation of Kenaf/Polypropylene Honeycomb Cores
… properties, as well as in-plane and out-of-plane shear properties of the flat sheets have been analysed by conducting experiments through ‘design of experiment’ methodology. Since melt flow indices and die temperature appear to be critical factors influencing the average and variation in the …

Development of Magnetorheological Elastomer System for Adaptive Vibration Isolation
… of the AB system, and large-scale component testing and evaluation. In addition, since no fabrication and testing systems were available in the market, testing and fabrication units were developed to facilitate the manufacturing of small and large-size MRE specimen, and a double-lap shear …

Crystallization, Morphology, Thermal Stability and Adhesive Properties of Novel High Performance Semicrystalline Polyimides
… polyimides. The BPDA based polyimide was also tested extensively as a structural adhesive using Ti-6Al-4V coupons. Additionally, these polyimides are based on monomers, that are presently commercially available. The bulk thermal stability of the polyimides was first evaluated using dynamic and …

Synthesis and Characterization of Aryl Phosphine Oxide Containing Thermoplastic Polyimides and Thermosetting Polyimides with Controlled Reactivity
… than that of the Tg of the primary structure. Lap shear test results indicated good adhesion to titanium when cured at 250°C -280°C. The cured materials showed high glass transition temperatures and good thermal and thermo-oxidative stability as determined by DSC, TGA and DMA. Good chemical …

Functional coatings deposited by an Atmospheric Pressure Plasma Jet (APPJ) system over Thermoplastic Elastomer (TPE) substrates
… characterization techniques together with the lap-shear test were used to study the influence of each precursor percentage. The main difficulty in this work lied in the hydrophilic character of APTES (for example, -NH2) and the low adhesion of the fluorinated coatings. On one hand, the sample …

The Thermal Stability of Anodic Oxide Coatings - Strength and Durability of Adhesively Bonded Ti-6Al-4V Alloy
The lap shear strength of chromic acid anodized, primed, Ti-6Al-4V alloy bonded with a high performance FM-5 polyimide adhesive has been investigated as a function of thermal treatment for selected times at various temperatures in air. The research findings indicate that the lap shear strength …
