In this work, poly(acrylonitrile‐butadiene‐styrene) (ABS) filaments containing 0, 1, 3, and 5 wt% multi‐walled carbon nanotubes (MWCNT) were prepared by extrusion. The filaments were then used to make the required specimens with a fused deposition modeling machine. The results obtained from the tensile measurements revealed that with the increase in the layer thickness, the tensile strength of the

In this study, the effect of carbon nano‐tubes (CNTs) and fiber carbons on vibration frequency of delaminated anti‐symmetric cross‐ply cylindrical shells is investigated. In this case, (CNTs) are added into polymer matrix of industrial composite. The mixture of rule and Halpin‐Tsai relation are used to obtain the effective materials of reinforced delaminated multi‐scale composite cylindrical shell

An smooth particle hydrodynamics/finite element (SPH/FEM) model was developed to simulate the erosion of zirconia particle‐reinforced epoxy composites, due to the overlapping impacts of angular particles at both perpendicular and oblique incidences. For each composite target, multiple sub‐volumes, each having their own random reinforcement distribution, were modeled. The reinforcements were assumed

This paper addresses the development of a digital twin, based on an inversion procedure, integrating process monitoring with simulation of composites manufacturing to provide a real time probabilistic estimation of process outcomes. A computationally efficient surrogate model was developed based on Kriging. The surrogate model reduces the computational time allowing inversion in real time. The tool

Nanocellulose of hemp fibers was obtained by employing the chemo‐mechanical technique, which included three stages of chemical treatments followed by mechanical grinding. Morphological analysis of untreated, treated, and nanocellulose of hemp fibers was performed by field emission scanning electron microscopy. Further, the crystalline behavior of these fibers was also measured by X‐ray diffraction

The ultrahigh‐molecular‐weight polyethylene (UHMWPE) has become the most widely used material for water‐lubricated bearings. In the research, the effects of introducing sisal fiber (SF) filler materials on the friction and wear characteristics of UHMWPE‐based composites were investigated. The composites were tested against the QSn7‐0.2 copper disc, under water‐lubricated conditions, using a specially

This study aims to combine carbon fibers and copper metallic wires using a rotary twister, and the employment of wire coating technique reinforces the mechanical properties of carbon fibers, creating more feasible applications. The proposed carbon (C)/copper (Cu)/polyester (PET)/polypropylene (PP)/acrylic (A) woven fabrics preserve the electrical conductivity of carbon fibers and metallic wires while

Conductive soy protein biocomposite plastics with high performance were fabricated with glycerol as plasticizer and nanosized carbon black (CB) as conductive filler. Adopting a pretreatment of the CB nanofiller, its dispersion, and interaction with matrix was improved. The results indicated the existence of strong hydrogen bonding between soy protein matrix and CB fillers, which improved the interfacial

Mechanical properties of carbon fiber (CF) reinforced plastic composites are influenced by physicochemical interactions between CF surfaces and matrix polymers. Poor interfacial adhesion between CF surfaces and matrix polymer molecules caused by inertness of graphitic carbon still remains to be solved. Deeper comprehension of the interfacial properties would promote advancement of technologies enhancing

The purpose of this study is to develop polymer composite masterbatches by using poly(lactic) acid as a carrier resin and bamboo charcoal particle as a natural pigment. Moreover, antioxidant and dispersing agent were added to the masterbatches where the antioxidant improves thermal and ultraviolent stability of pigment masterbatches while dispersing agent enhances the distribution and dispersion of

The modified graphene oxide (GO) with different specific functional groups were prepared and introduced into rigid polyurethane foam (PUF). It was proved that NCO groups were bonded on the surface of GO, which could participate into the polyurethane foaming reaction and dramatically improve the interactions between the filler and matrix. It was found that the cell morphology and the mechanical properties

Polymer matrix composites are well suited for applications in space environments due to their excellent specific strengths and moduli, thermal properties, and tailorability.

3D woven spacer fabrics connected with woven cross‐links and forming tunnels of trapezoidal shape were produced in single and double level configuration with four different cell wall opening angles in each configuration. The sandwich composites produced from these spacer fabrics were then analyzed for their out‐of‐plane compressive and flexural properties to study their failure loads, energy absorbency

The present world scenario demands for the utilization of natural fiber‐reinforced polymeric composites as opposed to synthetic fiber‐reinforced composites mainly due to their environmental friendly behavior, availability in abundance, cost‐effectiveness, and lightweight and moderately high‐strength properties. Along with the above said advantages, the ease of manufacturing of natural fibers has made
