In this study, discrepancies between the free vibration of fiber-metal laminate (FML) and composite cylindrical shells reinforced by carbon nanotubes (CNTs) based on Love’s first approximation shell theory have been considered by beam modal function model. The representative volume elements consist of three and four phases for composite and FML structures, respectively, which include fiber, CNT...

Composite materials made of fiber-reinforced plastic laminates are highly susceptible to surface damage caused by wear during contour milling, especially with inappropriate tool and cutting material properties. Improper choice tools conditions lead delamination between applied layers, thermal in the polymer matrix, reduction edge quality tools. The study was devoted circumferential milling twil...

Carbon fiber composites have become popular in aerospace applications because of their lightweight yet strong material properties. The injection molding process can be used to produce discontinuous fiber composites using less time and resources than traditional methods, thereby broadening carbon fiber composites’ applications in different industries. Utilization of longer fibers offers more loa...

We constructed an atomic structure model for a PANbased carbon fiber containing amorphous structures using molecular dynamics methods. It was found that basic physical properties such as crystallinity, Young’s modulus, and thermal conductivity of our model were nearly identical to those of real carbon fibers. We then obtained the tensile strength of a carbon fiber, which has no macro defects. W...

An active approach for initiating rigidization in carbon-fiber reinforced polymer (CFRP) composites unites electrical resistivity to mechanical stiffening. Temperature control is implemented in efforts to reduce the curing time of the composite and to increase control of the curing process. Specifically, proportional-integral (PI) feedback control of internal resistive (Joule) heating establish...

Carbon nanotubes (CNTs) are one of the most interesting nanomaterials because of their excellent characteristics. In this study, a transparent CNTs coating for cell culture dishes was developed and its properties for cell culture were estimated. Carboxylated multiwalled carbon nanotubes (MWCNTs) were dispersed in aqueous sodium cholate solution and applied on a collagen type I-coated cell cultu...

A simple method has been developed for the preconcentration of benzene and phenolic compounds (BPC) by the adsorption of its carbon nanotubes (CNTs). The preconcentration of benzene and phenolic compounds (BPC) are ubiquitous pollutants, and many of them are carcinogenic or mutagenic. Carbon nanotubes (CNTs) are a kind of novel and interesting carbon material which can be used for separation an...
