Purpose This research aims to exploit the potential of Ultrasonic Additive Manufacturing (UAM) in the embedding of printed electrical materials directly into the interlaminar region of parts during manufacture in order to realise novel multifunctional Metal Matix Composite’s (MMC’s). Design/methodology/approach To ensure the proper electrical insulation between the printed conductor and metal m...

As typical anchorage-dependent cells myocytes must balance contractility against adequate adhesion. Skeletal myotubes grown as isolated strips from myoblasts on micropatterned glass exhibited spontaneous peeling after one end of the myotube was mechanically detached. Such results indicate the development of a prestress in the cells. To assess this prestress and study the dynamic adhesion streng...

Texturing the surface of a PDMS fi lm with microscale pillars has been shown to enhance shear adhesion to a rigid substrate by an order of magnitude when compared to untextured control fi lms. In this study, it is shown that shear load is distributed uniformly among the contacts rather than concentrated on the contacts nearest the edge of the fi lm-substrate interface, which is in contrast to t...

The mechanical and physical properties of composite materials are greatly influenced by the structure and properties of fiber/matrix interface. Short beam shear test is often performed to evaluate the laminar interface properties in real applications, especially for studying them after a given hydrothermal treatment. However, the results depend on the interface and the matrix properties, so the...

The behaviour of a piezoelectric actuator is strongly affected by the bonding condition along the interface between the actuator and the host structure. The current paper represents an analytical study of the static effect of the mechanical and geometrical properties of the adhesive layer on the coupled electromechanical behaviour of a thin piezoceramic actuator bonded to an elastic medium. An ...

The performance of smart structures depends on the electromechanical behaviour of piezoelectric actuators and the bonding condition along the interface, which connects the actuators and the host structures. This paper provides a theoretical study of the effect of partially debonded adhesive layers on the coupled electromechanical behaviour of piezoelectric actuators subjected to high-frequency ...

The behaviour of a piezoelectric sensor is strongly affected by the bonding condition along the interface between the sensor and the host structure. The current paper represents an analytical study of the static effect of the mechanical and geometrical properties of the adhesive layer on the coupled electromechanical behaviour of a thin piezoceramic sensor bonded to an elastic medium. A sensor ...

A glass fiber reinforced plastic laminate, which consists of half-overlapped wrapped Kapton/R-glass-fiber reinforcing tapes vacuum-pressure impregnated in a cyanate ester/ epoxy blend, is proposed as the insulation system for the ITER Toroidal Field coils. In order to assess its mechanical performance under the actual operating conditions, cryogenic (77 K) tensile and interlaminar shear tests w...

most consumers prefer natural coatings to the chemical ones to act as an enhancement of storage quality of fruits. in this research, quality of thomson oranges coated with chitosan-clay nano composite edible coating plus fungicide-wax chemical coating was compared with a non-coated sample during storage for a period of 3 months through a factorial design (3×4). orange samples were kept in a col...
