“…The scanning electron micrographs were obtained using a scanning electron microscope (SEM; JEOL model JSM‐6510, Tokyo, Japan) operating at 10 KV. The measurements of glass‐transition temperatures, tensile tests, lap shear tests, and T‐peel tests were performed according to published methods, to which some changes were made when necessary. More specifically, the glass‐transition temperatures, T g , of the samples were evaluated using a differential scanning calorimeter (DSC; TA Instruments, model Q600, New Castle, DE).…”

In order to improve the adhesion strength of acrylic adhesive to untreated poly(ethylene terephthalate) (PET) substrate, two-component acrylic structural adhesives initiated by tributylborane were prepared. The effects of acrylic monomers, elastomers, decomplexers, and oligomers on the adhesion properties of two-component acrylic structural adhesive were investigated in sequence. It is found that the shear strength on PET of adhesives toughened by acrylonitrile-butadiene-styrene copolymer and carboxylterminated butadiene-acrylonitrile copolymer is higher than that of commercial adhesives Dp8010NS and Loctite 3030. A tailored oligomer was synthesized from hydroxyl propyl-terminated polydimethylsiloxane and 3-isopropenyl-a,a-dimethylbenzyl isocyanate. It is also noticed that premature failure usually takes place in the lap shear test samples due to the brittleness of the acrylic adhesive, except in the sample of adhesive modified by tailored oligomer. Excellent adhesion to the PET substrate is achieved by this adhesive modified by tailored oligomer, with a lap shear strength above 11 MPa and T-peel strength up to 5.34 N/mm. Additionally, the resulting adhesive is qualified for the structural bonding of PET materials.

“…Because adhesives are much weaker than the adherents they join, nanofiller-toughened adhesives, including CNTs, were considered to be a potential route to the progress in this domain. 88 For example, Hsiao et al 89 bonded two graphite fiber/epoxy composite laminates using MWCNTs. As low as 1−5 wt % content of MWCNTs yielded the improved shear strength of adhesion.…”

With a few works in 2010 on the application of carbon nanotubes (CNTs) in wind turbine blades (WTBs), new hope has arrived promising to conquer the so-far used materials. From that moment, several dozens of publications have been published confirming that CNTstypically considered as "universal soldiers" in the composite, hybrid, and hierarchical materialscould be a reliable component of WTBs. However, all of the experimental results, in a few cases supported by theoretical models, were obtained only at the laboratory scale. This review intends to answer the title question by summarizing the up-to-now efforts and comparing the levels of outperformance of CNT-based WTBs. The general conclusion from the review is that the physicochemical and mechanical properties of CNT-based WTBs, although promising, must be balanced by economy and technological aspects, with the reliability of large-scale synthesis and standardization of CNT batches as the key aspects.

An In-situ polymerization technique was used to create an epoxy nano-alumina composite adhesive. Ultrasonication was used to achieve the distribution of nano-alumina particles in an epoxy matrix containing weight percentage 0.5,1,1.5 and 2% nanoparticles. Single lap joints with adherents of Copper-Copper (CC), Mild Steel-Mild Steel (MM) and Copper-Mild Steel (CM) were prepared following ASTM D1002 standards. Lap shear strength tests in tension of bonded joint samples (CC, MM, and CM) were conducted on UTM at 1.27 mm/min cross head travel rate. The fatigue strength of bonded specimens was tested at a stress ratio of R 0.1 and a frequency 5HZ by following ASTM D3166 standards. Stress amplitudes of fatigue test were taken at 70%, 65%, 60% and 55% of shear strength of corresponding single lap joints. Six samples were tested to calculate the average number of cycles to failure. For each combination of joints shear strength and fatigue life were increased with an increase in wt.% but maximum increment was obtained at 1.5 wt.% of nanoparticles addition. An increment of 40% for CC joints, 66% for MM joints and 47% for CM joints was obtained in nanocomposite’s shear static strength containing 1.5 wt.% nanoparticles over neat epoxy joints. Increment in fatigue life of CC, MM, and CM joints at 1.5 wt.% of spherical nanoparticle inclusions was 401%, 500%, and 409% respectively.
