This paper presents the design, fabrication and characterization of a flexible solidstate electrical double layer supercapacitor fabricated in a single fabric layer. The proposed supercapacitors were based on fabric electrodes fabricated with low cost carbon materials via a spray coating technique. The single layer solid state supercapacitors achieved a specific capacitances of 40.5 F.g, area c...

wood is a naturally renewable material with both continuous and isolated pore systems. wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. however, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. using nano-materials are very easy in the wo...

car body lightening and crashworthiness are two important objectives of car design. due to their excellent performance, composite materials are extensively used in the car industries. in addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. hat shape energy absorber is used in car’s doors for side impact protection. the aim of these numerical models and exper...

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...

Abstract—Fabric textures are very common in our daily life. However, the representation of fabric textures has never been explored from neuroscience view. Theoretical studies suggest that primary visual cortex (V1) uses a sparse code to efficiently represent natural images. However, how the simple cells in V1 encode the artificial textures is still a mystery. So, here we will take fabric textur...

The penetration behavior of Kevlar fabric intercalated with dry particles and shear thickening fluids (STF), highly concentrated fluid-particle suspensions, is presented. In particular, the role of particle hardness is explored by comparing fabric treatments containing SiO(2) particles, which are significantly harder than Kevlar, to treatments containing softer poly(methyl methacrylate) (PMMA) ...

Abstract Preform is one of the important factors affecting mechanical properties textile composites. To further reflect influence preform structure on composite materials, angle interlocking and plain weave structures are configured in a certain proportion to form fabric with both structures. The results show that compound has positive effect improvement AERC. An increase organization configura...

The technical feasibility of the recycling specific polymeric composite materials was evaluated. Two types carbon composites, both with phenol-formaldehyde resin but different reinforcement, were studied. It discovered that solvolysis oxidizing agents used in an acidic environment allowed for achievement a high-efficiency fiber extraction. extracted secondary fibers had high degree purity (95–9...

Fibre metal laminates (FMLs) are lightweight structures with high structural performance and suitable for many industrial applications. This work describes the impact behaviour of novel sisal fibre-reinforced aluminium (SiRAL) their dependence upon orientations fibres, composite core used surface treatment skins. A cold-pressing technique is to produce SiRALs in six configurations. The FMLs her...
