Internal mixer is an important mixing equipment. After working for a long time, the end face of the internal mixer will be worn. The abrasion of the end face can increase the gap between the mixing chamber and the end face, and then material leakage occurs, which reduces the mixing effect and affects the performance of rubber compound. Therefore, it is very necessary to study the wear of the end face

In this paper, oil palm fiber (OPF) and pineapple fiber (PALF) reinforced biophenolic resin (BPHR) composites and hybrid composites were fabricated by hand lay-up technique. Structural, thermal and mechanical properties of pure and hybrid composites analyzed by Fourier transform infrared (FTIR), thermal gravimetric analyzer (TGA), dynamic mechanical analyzer (DMA), and universal testing machine. Achieved

This research work investigates the influence of hybrid particulate fillers, Mg–Al layered double hydroxide (LDH), and nanoclay (NC), on the mechanical properties and formability of glass laminate AA5052 epoxy composites (GLARE). The composite laminates were prepared by varying the weight percentage (i.e., 3, 4, and 5 wt%) of the hybrid fillers in the epoxy resin. The conventional hand layup technique

The biodegradable and naturally available waste Syzygium cumini particulates filled E-glass fiber laminate-reinforced composites were fabricated with different weight percentages. The present work is to develop a new composite from huge waste of S. cumini seeds. The two different combinations of composites with different concentration (10, 20, 30, 40, and 50 wt%) of reinforcement were fabricated through

A comparatively new approach for the manufacturing of metal parts is the use of fused deposition modeling (FDM). Here, a metal powder filled filament is processed to manufacture components (green part). The subsequent process chain is identical to that of metal injection molding (MIM). Thus, the polymer binder is initially removed from the component (brown part). The metal particles are finally sintered

Basalt fiber reinforced polymer (BFRP) bars have been widely studied because of its advantages in corrosive environment. At present, the researches on the bond properties of basalt FRP bars mainly focus on the types of bars, bond length and environmental effects. In this paper, the bond properties of 12 mm diameter glass fiber reinforced bars with unilateral and bilateral compressive stresses of

The continuous delivery of E-waste from petroleum-based products creates ecological and environmental problems due to non-biodegradable polymers, which release harmful chemicals and toxic gases. This results in biodegradable polymers/fibers appearance, which are biocompatible and degrade in the surrounding environments without causing any environmental pollution and these relieve environmental burden

To enhance the interfacial bonding between the graphene oxide nanoplatelets (GONs) and epoxy (EP) matrix, two different types of silane coupling agents (amino- and EP-silane) were applied to the GONs-EP nanocomposites. The effects of the silane compound type and silanized GON loading (0.1–0.5 wt% at an interval of 0.2) on the dry-sliding wear response of GONs-EP nanocomposites were then studied. The

Producing self-lubricating fabric composites with excellent wear resistance and long service life is desired for their use in practical application, yet still challenging. Therefore, a novel nanoparticle of talc-molybdenum sulfide (MoS2) hybrid nanosheets was synthesized via one-step hydrothermal reaction in this work and incorporated into the Nomex/polytetrafluoroethylene (PTFE) self-lubricating fabric

Dragonfly's wings are highly specialized flying organs that are well adapted to the flying behavior of each dragonfly, mainly consisting of veins and membrane. The effect of graphene nanoparticles on a novel foam-based sandwich panel structure inspired by microstructural features of dragonfly wings has been investigated under low-velocity impact. Composite and nanocomposite sandwich veins are made

Herein, the effects of different content of SnO2 on the stress, strain, and microstructure of AgCuO(10)SnO2(x = 2,5,8) composites during hot extrusion were studied by using finite element analysis and compared with the actual hot extrusion experiment. The results show that cubic CuO gradually becomes fibrous mainly due to shear strain during hot extrusion, but monoclinic CuO and SnO2 only produce

In this paper, the structural damping behavior of axisymmetric nanocomposite cylinders enhanced with randomly oriented graphene nanosheets has been explored by a mesh-free solution. The static responses of such nanocomposite cylinders under internal pressure and exposed to thermal environment are assumed as the initial condition of harmonic vibrations. Using the shape functions of moving least squares

In this work, multiscale basalt fiber/epoxy composites were fabricated using silane-modified Na+-montmorillonite nanoclay, at various contents (0.5, 1, 3, and 5 wt% with respect to the matrix). Flexural and tribological characteristics of the composites were studied. First of all, a silane coupling agent, namely 3-aminopropyltriethoxysilane (3-APTS), was applied onto the surface of the nanoclay particles

This study aimed to synthesize and characterize chlorhexidine (CHX)-loaded poly-L-glycolic acid (PLGA) nanoparticles and to investigate the in vitro drug release in different pH conditions, antibacterial, cytotoxicity activity, and mechanical properties of CHX-loaded PLGA-modified Transbond XT adhesive at tooth-bracket interface. PLGA nanoparticles with and without CHX were synthesized using emulsion

A high-performance compound epoxy resin system suitable for wet filament winding was designed. The glass transition temperature reached 181.3°C, and the tensile strength, tensile modulus, and elongation of the resin casting body were 90.82 MPa, 3312.72 MPa, and 4.17%, respectively. In order to explore the mechanism of microwave curing, the microwave curing kinetics of the composites was studied. Based
