Structure, magnetic and mechanical properties of the nanocrystalline composite material of the SILAME® type were tested. The composite material was obtained by solidification of the nanocrystalline powder obtained in the high energy grinding of the initially crystallized Co68Fe4Mo1Si13,5B13,5 amorphous strip with the silicon polymer. The metallic powder was mixed with the silicon polymer in a different weight ratio and next the effect of Co68Fe4Mo1Si13,5B13,5 powder weight ratio on the magnetic and physical properties of the composite was investigated.

Creep Characteristics

AbstractThe creep test is one of the important approaches to determining some mechanical properties of composite materials. This study was carried out to investigate the creep behaviour of an epoxy composite material that was reinforced with Y2O3 powder at weight ratios of 2%, 7%, 12%, 17% and 22%. Each volume ratio was subjected to five loads over the range of 1N to5N at a constant temperature of 16 ± 2°C. In this work, creep behaviour, stress and elasticity modulus were studied through experimental and numerical analyses. Results showed that increasing the weight ratio of Y2O3 powder enhanced creep characteristics.

This paper studies a polymer composite material - a unidirectional organoplastic based on Rusar-NT aramid fiber and a melt epoxy-polysulfone binder. Organoplastic has the following mechanical properties: tensile strength 2060 MPa, Young's modulus 101 GPa. The microstructure of the fiber and the polymer matrix in the organoplastic samples was studied before and after tensile tests. The features of the formation of the binder structure depending on the packing density of the fibers in organoplastics have been determined. The nature of the destruction of fibers and polymer matrix caused by the uniaxial tension has been studied.

The current work reports on the fabrication of composite matrix from saw dust (SD) and recycled polyethylene terephthalate (PET) at different weight ratio by flat-pressed method. Wood plastic composites (WPCs) were made with a thickness of 15 mm after mixing the saw dust and PET followed by a three phase press cycle. Physical properties (Density, Water Absorption (WA) and Thickness Swelling (TS)) and Mechanical properties (Modulus of Elasticity (MOE) and Modulus of Rupture (MOR)) were determined base on the mixing ratios according to the standard. WA and TS were measured after 2 h and 24 h of immersion in water. The results showed that as the density increased, the SD content decreased from 90 % to 50 % into the matrix. However, WA and TS decreases when the PET content increased in the matrix. Remarkably, the MOE and MOR attained a maximum point at 964.199 N/mm2and 9.03 N/mm2respectively in 50 % SD content. In comparism with standard, boards D and E can be classified as medium density boards while A, B and C are low density boards. The results indicated that the fabrication of WPCs from sawdust and PET would technically be feasible for indoor uses in building due to favorable physical properties exhibited. The mechanical properties response showed that it cannot be used for structural or load bearing application.

Response Variable

This research evaluated, with the of the analyses of variance (ANOVA), a composite material based on epoxy matrix phase reinforced with Portland cement (CP-II) particles (0%wt [100%wt of resin], 20%wt, 40%wt, 60%wt). The response-variable investigated were modulus of elasticity (E) and compressive strength (S), bulk density (ρB), apparent density (ρA) and porosity (P). The highest values of the modulus of elasticity were provided from the composites manufactured with 40wt% of cement addition. The inclusion of 60% of cement implies in a reduction in the mechanical properties when compared with the results of the composite manufactured with 40% of cement. For the physical properties, the gradually inclusion of cement provides increasing in the density of the composites, and reduce the porosity of the materials manufactured.

Now a days composite material plays an important role in many industrial applications due to their excellent mechanical properties. Presently researchers are making composite materials using various filler materials to characterize the wear behavior of the composite which is used as a machine component in various industrial applications and in machine house hold articles for daily use to highly sophisticated applications. This is due to the proven fact that composite materials acquire higher strength to weight ratio. In this investigation Nano composites of E-Glass fiber/Multi walled carbon nano tube were prepared by the technique of hand layup. The glass fiber used for current investigation is E-glass fiber bi-directional of 45 degree orientation. The composite material samples were prepared in the form of a plate with a thickness of 4 mm. The fabricated composite materials were cut into analogous profiles as per ASTM for tensile and flexural testing analysis. This investigation reveals that the growth of Multi Walled Carbon Nano Tube (MWCNT) particles improves considerably the mechanical properties even if the fabrication is done by manual method like the technique of hand layup.

Structural Applications

Over the past two decades it has been established that composite materials are the leading emerging materials. The natural fibres present a number of advantages over traditional synthetic fibres because of their better corrosion resistance, excellent thermo-mechanical properties and high strength to weight ratio. Also the composite materials play an important role in maintaining the eco-friendly design requirements. Among this, polymer matrix composite is one of the recent developing sectors on the composite field, because it has high strength with less density as compared to the metal matrix composite. Depending on the applications, the properties of the polymer reinforced composite are improved by modifying compositions, process of fabrication and direction of fibre etc. In this analysis the Roselle Fibre (Hibiscus Sabdariffa) is reinforced with polymer composite by wt % in the mode of compression molding. The mechanical properties of the above fabricated material were analyzed by ASTM Standards and also the characterization of polymer composites were analysed using SEM. The compressive strength and the hardness value were high as compared to other strength properties; hence it is more suitable for compressive and structural applications. The results concluded that the treated fibre with chemical reveals better compatibility with polymer matrix than that of untreated fibre.
