This paper explores the characterization of Kevlar composite materials using Raman spectroscopy. The goal of the research is to develop and understand the Raman spectrum of Kevlar materials to provide a foundation for the development of nondestructive evaluation (NDE) technologies based on the interaction of laser light with the polymer Kevlar. The paper discusses the fundamental aspects of exp...

Fiber dimension and durability are recognized as important features in influencing the development of pulmonary carcinogenic and fibrogenic effects. Using a short-term inhalation bioassay, we have studied pulmonary deposition and clearance patterns and evaluated and compared the pulmonary toxicity of two previously tested reference materials, an inhaled organic fiber, Kevlar para-aramid fibrils...

This manufactured by Vacuum Assisted Resin Transfer Moulding (VARTM) method. method uses vacuum pressure difference causes bonding fiber- metal surface epoxy resin. In alloy act as core material a face skin. fiber-metal will have enhanced mechanical properties th...

In increasing the tensile strength of waru tree bark fiber composite (Hibiscus tiliaceus), it is necessary to have a combination reinforcement used in material. One materials that can be combined carbon kevlar. Kevlar has several advantages, including low density, absorbing vibrations well, and resistant chemical solutions. The specific objectives this study were determine maximum strain stress...

Concrete is a brittle material due to its poor tensile strength; consequently, concrete tends crack or peel under an applied external load. Previous studies have investigated the effect of incorporating fiber into concrete, which can improve strength. In this study, static and dynamic mechanical characteristics three types fiber-reinforced (FRC) were examined: carbon-fiber-reinforced (CFRC); Ke...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Composite materials are widely used because of their extreme properties. Researchers working on fabrication of new composite materials worldwide to enhance the applicability of these materials. There are very few works about the effect of nanoclay ...

In this article, the mechanical and three body abrasive wear behavior of Bidirectional and short Kevlar fiber reinforced epoxy composites at five different fiber loading (10wt%, 20wt%, 30wt%, 40wt% and 50wt%) have been evaluated. The mechanical properties i.e. tensile strength, flexural strength, inter-laminar-shear strength, and impact strength are performed to notice the behavior of mechanica...

Fiber-metal laminates (FMLs) such as Kevlar reinforced aluminum laminate (ARALL), 18 Carbon reinforced aluminum laminate (CARALL), and Glass reinforced aluminum laminate 19 (GLARE) offer great potential for weight reduction applications in automobile and aerospace 20 construction. In order to investigate the feasibility for utilizing such materials in the form of 21 laminates, sheet hydro-bulgi...

Mechanical properties of hybrid braided composite rebars are evaluated and compared to theoretical predictions which account for specific processing parameters including yarn size, braiding machine setup, and fiber type. Using a combination of high modulus carbon (Thornel P-55S) and aramid (Kevlar 49) fibers bars have been produced of up to 10 mm diameter with a Young's modulus of 200 GPa, a bi...
