... (SEM)/energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and atomic force microscopy (AFM). Nanoindentation and scratching experiments were conducted to study the mechanical and adhesion behavior. Multi-pass scratch tests were conducted under different sliding conditions. Results showed...

... properties of the composite material. Flexural results indicated homogeneity with improvements in mechanical properties of up to 15% in strength as well as modulus enhancement of up to 25%, respectively. Interfacial adhesion and dispersion were improved with viscosity reduction while utilizing the secondary...

... of these composites were evaluated in this study. Morphology of modified surfaces of jute fabrics examined using scanning electron microscopy and Fourier transform infrared spectroscopy revealed improved surfaces for better adhesion with matrix. Nanoclay infused samples demonstrated lower moisture and water...

... the morphology, microstructure, hardness, scratch resistance, and adhesion strength of the Al 2 O 3 films were progressively imprinted. The FB process led to the deposition of a good-looking and well-adhered graded Al 2 O 3 coating, which was found to be progressively richer in Al 2 O 3 on moving from...

...Christos F. Karanikas; Han Li; Joost J. Vlassak; James J. Watkins A fivefold increase in adhesion energy is observed for poly(acrylic acid) (PAA) modified Cu/TaN interfaces in which the thin copper films are deposited by the hydrogen assisted reduction of bis(2,2,7-trimethyloctane-3,5-dionato...

... with an exception of samples with a base metal thickness of 500 μ m . Based on the results, it was proposed that microfriction at consolidation interfaces plays an important role for joint formation, and localized plastic flow around fibers is important to have fibers fully and safely embedded. adhesion...

...E. Dilara Koçak Producing composites from natural fibers is known to be common. These fibers benefit from their mechanical performances, low density, and their biodegradability. However, it is necessary for the fibers to form adhesion in the matrix. Therefore, it is necessary to apply a chemical...

...Ahsan Ahmed; Atef Fahim; Hani Naguib The design of metal-polymer foam adhesion and load transfer characteristics is carried out in this research work. The metal inserts are used as the load transfer component, while the foam is used as the structural element of the system. The inserts are embedded...

... general case of arbitrarily oriented nanotube rafts. The analysis in part I is based on the JKR theory of adhesion and linear elasticity for aligned multiwalled carbon nanotube raft configuration. It gives rise of several interesting predictions. First, two surfaces covered by aligned nanotubes can adhere...

... of adhesion is adopted. With the incorporation of three-dimensional contact configuration that features the inclined contact, we are able to show that the abnormal tribological behavior, in drastic contrast to the classical Amonton’s law, persists for both inclined and randomly oriented rafts. Consider...

... finite deformation, in combination with an adhesion criterion similar to the JKR theory, on the other hand, predicts a declining law between the frictional force and the pressure. The correlation of the data obtained through the atomistic and the continuum approaches relies on a deeper understanding...

...Deok-Bo Lee; Toru Ikeda; Noriyuki Miyazaki; Nak-Sam Choi The effect of bond thickness on the fracture toughness of adhesive joints was investigated from a microstructural perspective, using compact tension (CT) adhesive-joint specimens with different bond thicknesses. The adhesive material...

...Masaaki Iwasa; Toshio Hattori The fatigue strength of two types of FRP/metal adhesive joints at low temperature, a double lap joint and an embedded joint, was evaluated analytically and experimentally. First, the stress singularity parameters of the delamination edges under mechanical and thermal...

... is increasing. The length of the adhesion zone decreases and the length of the friction zone increases further. The absolute maximum of the pullout force P max is reached. The slip at the unloaded fiber end is unequal to zero s fe > 0 . The fictitious crack tip reaches...

...Deok-Bo Lee; Toru Ikeda; Noriyuki Miyazaki; Nak-Sam Choi The fracture behavior of an interface crack tip has significant influence on the structural integrity of an adhesive joint. We investigate a damage zone and the deformation of rubber particles around a tip of an interface crack between rubber...
