Peripheral such as aerospace, armor, sensors, heat exchanger, automobile, storage, and any other electronic equipment are frequently subjected to varying mechanical and thermal stress, which substantially influence their reliability, life cycle, and performance. The aerospace sector, for example, is in constant research for the decrement in mass to achieve higher fuel efficiency through light weighting

This work presents a method of industrially viable processing of nanocellulose‐reinforced polyamide 6 (PA 6). Cellulose nanocrystal (CNC)‐reinforced PA 6 is gaining attention as a promising material for use in the automotive industry due to its highly crystalline, low density, and environmentally friendly nature. However, the low‐thermal degradation temperature of CNCs presents problems when melt processing

A novel type of sandwiched separator for lithium‐ion batteries has been developed by combining electrospinning and electrospraying techniques. This separator consists of three layers in which the top and bottom layers are prepared by electrospinning a poly(amic acid) ammonium salt (PAAS) solution and the middle layer is obtained by electrospraying a mixture of the PAAS solution and inorganic nanoparticles

Pullout simulations were conducted to investigate the interfacial shear properties between defective graphene (DGr) and polymethyl methacrylate (PMMA) through molecular dynamics simulations with ReaxFF reactive force fields. The effects of number of defects (Stone‐Wales [SW] and double‐vacancy [DV] defects) were investigated. Our results showed that these two types of defects can obviously enhance

Polyimide (PI) and polyetheretherketone (PEEK) are superior high‐performance thermoplastics being extensively used in the fields of fiber‐reinforced polymer composites. However, there is very limited literature addressing the machining behavior of the PI and PEEK composites. The present paper aims to conduct a comparative study into the machining characteristics of these two representative high‐performance

In this paper, a new polyether titanate coupling agent (Ti4000) was used to modify basic magnesium carbonate (BMC), and Ti4000 modified BMC (Ti4000‐BMC) was characterized by X‐ray powder diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and X‐ray photoelectron spectroscopy. Then, PVC composites were prepared by adding BMC or Ti4000‐BMC into soft PVC matrix via melt

Improving the interfacial compatibility of plant fibers and polymer matrices still is an ongoing challenge in the application of natural fiber/polymer composites. In this study, the graphene oxide (GO) was grafted onto alkali‐treated bamboo fiber (ABF) surfaces, and then a GO‐ABF/polypropylene (PP) composite was prepared using a mini‐injection molding technique. The chemical properties of the GO‐ABF

Commercial rubber is hardly considered as raw materials to manufacture multifunctional shape‐memory polymers (SMPs) because it is difficult to either tune its glass transition temperature or introduce crystalline domains. Here, we report the manufacture of luminescent SMP composites based on commercial carboxylated nitrile rubber and rare earth organic complex (REOC) with Sm3+ ions. The dispersion

Glass fiber‐reinforced polymers are widely used in structural systems as load‐bearing elements at both high and low temperatures. This investigation presents the evaluation of glass fiber‐reinforced unsaturated polyester under quasi‐static tension loading at extremely cold temperatures. This work includes the preparation of polyester resin sheets and E‐glass fiber cloth reinforced polyester composite

In this study, graphite nanoplatelets (GNPs) were dispersed in a copolymer matrix consisting of bisphenol‐A based benzoxazine (BZ) and bi‐functional cycloaliphatic epoxy (CER), using two solvent‐free techniques: ultrasonication and three‐roll mill (3RM). The effects of GNP addition on the tensile performance, storage modulus, glass‐transition temperature (T g ), and electrical conductivity were evaluated

This study examined the morphological, rheological, viscoelastic, electrical, and microwave attenuation properties (RADAR absorbent and EMI shielding) of cyclo‐olefin copolymer (COC) composites prepared with the melt mixing method by using different amounts of graphite (0‐75 phr). Rheological percolation threshold of the graphite was determined as ∼38 phr. The RL analyses of the composites showed that

The excellent properties of the composites distinctly depend on the filler particles dispersion, which has close relationship with the surface treatment of filler particles. To improve the compatibility between the filler particles and the matrix, the surface of filler particles is generally treated with coating agents, which can be classified as “dispersants” and “coupling agents.” Coating calcite

A chopped‐glass fiber/multi‐walled carbon nanotubes (MWCNTs) hierarchical reinforcing structure was used to toughen the core‐face interlayer of sandwich materials. Chopped‐fiber mats modified by MWCNTs‐COOH were inserted at the face‐core interface before resin infusion. Sandwich beams were prepared by vacuum‐assisted resin transfer molding, containing a Polyvinylchloride (PVC) foam core covered with

An analytical multiscale model is presented in this article for the analysis of functionally graded nanocomposites. The multiscale scheme is composed of a microscale problem whose solution provides the constitutive model for the macroscale problem. For nanoparticle‐reinforced composites, the microscale problem consists of three phases, namely the nanoparticle, the matrix, and an interphase layer between

Even if the carbon nanotubes (CNTs) and their derivatives are commonly used as reinforcing phase in composite materials, also in commercial products, their tendency to agglomerate generally determines a scarce dispersion, thus not maximizing the effect due to the second phase. In this article, a perfect dispersion of highly entangled nanotubes was achieved by using a very simple approach: exploiting

The stickiness of prepregs (tack) is considered a decisive material property for the success of high‐quality composite manufacturing by automated lay‐up processes such as automated fiber placement (AFP) or automated tape laying (ATL). Adverse control of prepreg tack can easily result in laminate defects or machine breakdown, which are highly undesirable considering the tremendous machinery and material
