In this research, quasi-static penetration and ballistic properties of non-woven kenaf fibres/Kevlar epoxy hybrid laminates with thicknesses ranging from 3.1 mm to 10.8 mm by hard projectile at normal incidence have been experimentally investigated. Hybrid composites were fabricated by hand lay-up technique in a mould and cured at room temperature for 24 h by static load. Hybrid composites cons...

this article gives an approach to predict the springbackward phenomena during post solidification cooling in a functionally graded hybrid composite cylindrical shell with transverse isotropic structure. here the material properties are considered to be given with a general parabolic power-law function. during theoretical analysis, appropriate transform is introduced in the equilibrium equation ...

In the present study, room temperature mechanical properties of pure magnesium, Mg/ZrO₂ and Mg/(ZrO₂ + Cu) composites with various compositions are investigated. Results revealed that the use of hybrid (ZrO₂ + Cu) reinforcements in Mg led to enhanced mechanical properties when compared to that of single reinforcement (ZrO₂). Marginal reduction in mechanical properties of Mg/ZrO₂ composites were...

Combining conductive micro and nanofillers is a newway to improve electrical conductivity. Micrometric silver flakes and nanometric carbon nanotubes (CNTs) exhibit high electrical conductivity. A new type of hybrid conductive adhesives filled with silver flakes and carbon nanotubes (DWCNTs or MWCNTs) were investigated. High electrical conductivity is measured as well as improved mechanical prop...

Carbon fiber-reinforced multi-layered pyrocarbon-silicon carbide matrix (C/C-SiC) composites are widely used in aerospace structures. The complicated spatial architecture and material heterogeneity of C/C-SiC composites constitute the challenge for tailoring their properties. Thus, discovering the intrinsic relations between the properties and the microstructures and sequentially optimizing the...

The experimental investigation of hybrid metal matrix composites with fly ash and graphite reinforced aluminium alloy (Al 6061) composites samples, processed by stir casting route are reported. The aluminium alloy was reinforced with 3 wt.%, 6 wt.%, 9 wt.% fly ash and fixed 3 wt.% of graphite to mixture the hybrid composite. Hardness of the hybrid composite were tested it was found that when th...

the accumulative roll bonding process is used as a severe plastic deformation technique to produce aluminum composite sheets with ultra fine structure. in this study the effect of simultaneous use mg and sic particles as reinforcements, on the tensile properties of the al-mg-sic hybrid compositeis studied. the al-mg-sic hybrid composites with different amounts of mg and sic contents were fabric...
