A new class of functionalized graphene-filled solderable isotropically conductive adhesive (ICA) has been developed using a low-meltingpoint alloy (LMPA) fillers. The mechanical and electrical characteristics of formulated ICAs were investigated and compared with those of three kinds of conventional ICAs filled with Ag particles. The functionalized graphene-filled solderable ICA formed good met...

In this laboratory study shear bond strengths of three filled and one unfilled adhesive systems to enamel and dentine were compared. Forty-eight extracted intact noncarious human mandibular molars were randomly assigned to two groups of 24 one for bonding to enamel and the other for bonding to dentine. Buccal and lingual surfaces of each tooth were randomly assigned for application of each one ...

Appendix 1-Experimental Details Preparation of the conductive adhesive tracks was accomplished by first mechanically mixing a typical thermoset type of adhesive test vehicle with a loading between 78-85 wt% of silver-plated copper to form a uniform paste. The composition is then applied onto a substrate to form conductive traces or electronic circuitry. Usual methods of applying the composition...

BACKGROUND AND AIMS Effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. The aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µSBS) of silica- (Spectrum TPH) and zirconia-filled (Filtek Z250) composite resins. MATERIALS AND METHODS Twenty-seven composite resin blocks...

We propose an analytical model to predict the adhesives penetration into hard wood. Penetration of hard wood is dominated by the vessel network which prohibits porous medium approximations. Our model considers two scales: a one dimensional capillary fluid transport of a hardening adhesive through a single, straight vessel with diffusion of solvent through its walls and a mesoscopic scale based ...

Most of the structures in Civil Engineering consists in assemblies of deformable bodies, thus it is of interest to dispose of efficient models of junctions between deformable solids. The classical schemes of Continuum Mechanics lead to boundary value problems involving several parameters, one being essential: the (low) thickness of the layer filled by the adhesive. For usual behaviors of the ad...

BACKGROUND To compare the shear bond strength of brackets with and without enamel etching. MATERIAL AND METHODS In this study, 60 sound premolars were randomly divided into four different groups: 1- TXE group: Enamel etching+Transbond XT adhesive+ Transbond XT composite. 2- TXS group: Transbond plus self-etch adhesive+ Transbond XT composite. 3- PQ1E group: Enamel etching+ PQ1 adhesive+ Trans...

The mechanical behavior of electrically conductive adhesive joints exposed to elevated temperature and relative humidity conditions has been investigated, and failure mechanisms of conductive adhesive joints have been determined. Three model, silver-filled, epoxy-based adhesive systems have been studied in conjunction with printed circuit board (PCB) substrates with metallizations of Au/Ni/Cu a...

In the present paper, a novel epichlorohydrin/cardanol adhesive was reinforced by multi-walled carbon nanotubes (MWCNTs) and characterized experimentally. The MWCNTs in weight ratios (wt %) of 0.5%, 1.0% 2.0%. bulk properties were through dynamic mechanical analysis tests, tension fracture toughness while its shear behavior single-lap tests on aluminum composite bonded specimens. morphology usi...
