in the present research work, the flexural modulus and strength of glass fiber-epoxy resin and carbon fiber-epoxy resin composites have been enhanced through fiber tension during curing of the polymeric resin. this study showed that the tension applied on the fibers increased the flexural modulus of the glass-epoxy composites up to 12% and the flexural strength up to 19%. the flexural modulus a...

This paper demonstrates the feasibility of replacing the metal coil spring with the composite coil spring. Three different types of springs were made using glass fiber, carbon fiber and combination of glass fiber and carbon fiber. The objective of the study is to reduce the weight of the spring. According to the experimental results the spring rate of the carbon fiber spring is 34% more than th...

Room temperature magnetic field effects have not been definitively observed in either single-walled carbon nanotubes (SWCNTs) or C₆₀ under a small magnetic field due to their weak hyperfine interaction and slight difference of g-factor between positive and negative polarons. Here, we demonstrate charge-transfer induced magnetic field effects in nano-carbon C₆₀-SWCNT bulk heterojunctions at room...

radar absorbing materials, i.e. magnetite (fe3o4) coated carbon fibers (mccfs) were fabricated by electro-deposition technique. black-colored single spinel phase fe3o4 nanoparticles was easily synthesized by hydrothermal method using reduction of a fe (iii) - triethanolamine complex in an aqueous alkaline solution at 60-80 ◦c. uniform and compact fe3o4 films were fabricated on nitric acid treat...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper presents a high-Q MWCNT (Multi Wall Carbon Nano-Tube) network based pulse-shaped on-chip embedded nano-inductor for power electronic circuits. This high-Q inductor is fabricated using a composite of MWCNT (multi Wall Carbon Nano Tube) network and Fe in semiconductor processing environment. A layer of nano composite film (Cu/CoFe2o4) is pat...

Catalytically grown carbon nanofibers (CNF) are a newly developed type of material produced from the decomposition of selected carbon-containing gases over metal particles. These materials consist of nano-sized graphite platelets separated a distance of at least 0.335 nm and stacked in various orientations with respect to the fiber axis. Such an arrangement results in a unique structure that is...

The review addresses the effect of various carbon and iron-based percentage nano- additives on both electromagnetic (EM) wave mechanical properties composite materials. It also assessed influence particle fiber size along with manufacturing process, (tensile strength flexural strength), fracture behaviors (fracture toughness) (reflection loss). Reviewing selection nanomaterials for a particular...
