TL;DR: In this paper, the authors determined the curing kinetics of polymeric diphenylmethane diisocyanate and wood mixtures containing various moisture contents by means of differential scanning calorimetry.

TL;DR: A polyether, moisture curable, polyurethane resin was used as an adhesive on plastic and aluminium substrates, in order to investigate the influence of the surface properties on adhesion.

TL;DR: In this article, the influence of photo-initiators and their mixtures on the polymerization rate of the adhesive compositions were studied and the results showed that the mixture Irgacure 184 provides synergic effects of surface and through curing.

TL;DR: In this paper, the dimensional stability and shear strength of laminated veneer lumbers were measured after being exposed to steam for 2, 6, 12, 24, 48 and 96h periods according to the procedure of the Turkish Standards (TS) 3639.

TL;DR: In this paper, a new form of dismantlable adhesive technology has been developed, which makes it possible for the bonded building materials to be separated by the simple application of heating over 100°C.

TL;DR: In this paper, the correlation between the surface characteristics of composite materials and adhesion performances of corresponding surfaces assemblies is analyzed. And the importance of considering a polymer composite surface not only as a polymer entity, but also as a fibre/polymer unit.

TL;DR: In this paper, two kinds of high-temperature adhesives (HTAs) were prepared for graphite joints and the joining strength was tested at room temperature and the results showed that the graphite joint exhibit satisfactory bonding strength and that ceramics fillers show a marked property modification effect.

TL;DR: In this article, the effects of the properties of the substrates and tackifier on the characteristics of the SIS-based hot-melt pressure-sensitive adhesives (HMPSAs) were investigated.

TL;DR: In this article, the authors investigated the effect of a forced air plasma pre-treatment on surface chemistry and bond strength of a commercial grade polypropylene material, which was used to pre-treat and bond a full size automotive bumper assembly with a polyurethane (PU) adhesive.

TL;DR: In this paper, the defects that are a concern in adhesively bonded joints and how these were simulated with artificial imperfections are reviewed and a subsequent evaluation of the defect bond area with image analysis enables a correlation to strength.

TL;DR: In this article, the Toray Lab-carbon fibers measured by the single fiber fragmentation was determined to be in a similar level to AS-4 and IM-7 in various epoxy-amine thermoset systems and polycarbonate thermoplastic matrix.

TL;DR: In this paper, a finite element analysis was conducted for double lap, metal-to-metal bonded repair joints with different linear edge taper angles, or optimal taper profiles using the shape optimisation approach.

TL;DR: In this article, the influence of metal fillers on water/moisture sorption characteristics of adhesives was investigated and it was found that there is no significant effect of aluminum filler content on moisture diffusivity in epoxy adhesive specimens while adding aluminum filler into epoxy decreases the total amount of water intake at saturation.

TL;DR: In this paper, the authors used the depth sensing indentation (DSI) technique to investigate the distribution of mechanical properties through the bondline for several adhesive joints and to compare this with the mechanical properties measured from bulk adhesive samples used for conventional uniaxial testing.

TL;DR: In this article, an analytical model for understanding crack propagation behavior of adhesively bonded cracked double-lap shear joints subjected to tension-tension fatigue loading is presented, which can be used to calculate the bending moments at the cross sections of the crack tips and strain-energy release rates at the two crack tips.
