New polyurethane compositions with polyols based on propylene glycol and glycerin have been studied. The technological parameters of the adhesive composition were determined: start time, gelation life (tack-free) time. for maximum elasticity line has developed.

This work is the first systematic study on static behavior of adhesively-bonded Fe-SMA-to-steel joints in applications adopting iron-based Shape Memory Alloys (SMAs). In order to provide a better understanding mechanical adhesively bonded joint, an experimental campaign was established, involving 24 lap-shear tests displacement-controlled loading regime. The test series includes two types Fe-SM...

Adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. On the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. The scope of this paper is experimental investigation on the effects of the addition of Alpha-alumina nanoparticles to the ...

In this paper, the results of imaging experinents with the interfacial region~ of representative solid material joints, ~1ng a transmission-type scanning acoustic microscope operating at 150 HHz, are reported. Voids and flaws in specially made joints as well as production-line silicon solder bonds (die bonded headera' have been detected using the transmission~de of operation of the microscope. ...

Crack-sensing capabilities of a carbon nanotube (CNT) doped adhesive film have been analysed from coupon level to composite repaired panel. Mechanical performance is not negatively affected by the addition CNTs, due their good distribution inside adhesive. Moreover, electrical resistance increases with displacement in both Single Lap Shear (SLS) and Mode-I joints, combined effect deformation cr...
