“…Since the IFSS value of CNT/BPDA-PDA PI composites has not been tested experimentally yet, we have no accurate data to which to compare. However, it is still meaningful that our simulation value is in the reasonable range for other CNT/polymer composites [3][4][5]. Therefore, this work provides not only a prediction of the IFSS as a function of the CNT walls, but also molecular-level details of the interfacial interaction between BPDA/PDA and CNTs that impact those IFSS values.…”

“…Carbon nanotubes (CNTs), due to their high aspect ratios, have been regarded as one of the most promising reinforcement material in polymer-based nanocomposites [1][2][3][4][5][6]. Using pullout experiments with atomic force microscopy, the interfacial shear strength of CNTs within polymer matrices have been measured in the range of 35 to 380 MPa [7,8].…”

AbstractWith molecular dynamics simulations, nanocomposites were characterized that are comprised of a polyimide (PI) polymer and carbon nanotubes (CNTs) with the same outer diameter but with one, two, or three walls. The simulations indicate that the PI/CNT interaction is strong, regardless of the number of CNT walls, and that there is some degree of alignment of the PI chains near the CNT interface. As the number of CNT walls increased, the density of PI chains near the CNT interface also increased and the average radius of gyration of the PI chains decreased, and these observations were attributed to changes due to the intertube van der Waals interactions. From simulations of the constant force pullout process of the CNT from the PI matrix, the limiting pullout force was calculated to be higher for the triple-walled CNT than for the single-walled one. The interfacial shear strength of the nanocomposites was also calculated from the pullout energy, and the results indicate that increasing the number of walls is a critical factor for enhancing the interfacial stress transfer during tension.

Wooden structure restorationwork in historical buildings requires substitution and/or reparation of structural elements. The aim of this investigation is to compare the density, wave velocity, dynamic module, and quality factor intest pieces of solid wood, laminated wood and a multimaterial of P. pseudostrobus. The work hypothesis proposes that dynamic modules of laminated wood and multimaterial laminated wood reinforced with stainless steel mesh are, at least, equal to solid wood. Small dimension test pieces made of solid wood, laminated wood, and multimaterial wood elaborated with the species P. pseudostrobus were prepared. Humidity content and apparent density of wood were determined. Ultrasound tests in radial, tangential, and longitudinal direction were doneand wave velocity, dynamic module, and quality factor were determined. Empiric evidence indicates that wave velocity, dynamic module, and quality factors are different with the three kinds of test pieces. Laminated wood and multimaterial wood characteristics are similar to P. pseudostrobus solid wood; so that the two compound material have good expectations to substitute some pieces that work as resistance elements in wooden structures.

“…The effi cient solution of anticorrosion metal protection is offered by the formation of complex protecting coating systems consisting of a base paint with the content of nontoxic anticorrosion pigments of inorganic nature and of a top coat that ensures pronounced barrier effects and contains substances preventing the decomposition of a binder exposed to UV radiation [3,4]. The protective properties of organic coatings are dependent, among other factors, on their impermeability to liquids and gases [5][6][7]. Protective fi lm impermeability to liquids and gases can be improved by using nonisometric fi llers [8,9].…”
