25. Mechanical behavior and water absorption in sisal/glass hybrid composites
ABSTRACT This study aimed to assess the effect of hybridization on thermomechanical properties and water absorption of composite materials, by introducing sisal fiber tissue into the material. To that end, two composite material plates were manufactured, the first with five layers of E-glass reinforcement mat and the second with three layers of E-glass fiber

26. Weibull analysis of tensile tested piassava fibers with different diameters
ABSTRACT Environmental considerations in addition to technical, economical and societal benefits are increasingly promoting the substitution of natural fibers for glass fiber in polymer matrix composites. However, natural fibers are heterogeneous in their dimensions, specially the cross section, which plays an important role in their mechanical strength. It

27. Evolución microestructural de una aleación de aluminio A356 con y sin reforzamiento. de SiC sometida a molienda mecánica
ABSTRACT The effect of milling time on the crystallite size, microstrain and Vickers microhardness, of an aluminum alloy A356 (Al-7wt % Si) with and without SiC reinforcement (15 wt%) was studied. The metal alloy powders were obtained by the rotating electrode process (REP) from cylinders of the alloy, the obtained powders present spherical morphology with a

28. Reinforcement of poly (vinyl alcohol) films with alpha-chitin nanowhiskers
Abstract Composites Films were produced using Poly (Vinyl Alcohol) as the soft material and reinforced with Chitin Nanowhiskers(NWCH) as the rigid material. The present work studies the reinforcing mechanisms of NWCH in PVA films, made through a solvent casting technique and characterized for their calorimetric, swelling and mechanical properties. DSC tests

29. Study of the microstructure and mechanical properties of beta tricalcium phosphate-based composites with alumina addition produced by powder metallurgy
Abstract The use of alumina as a reinforcement in metallic and ceramic matrix is well-known. The purpose of this study was to investigate the effect of alumina addition according to its amount on the microstructural and mechanical behavior of tricalcium phosphate ceramic (TCP), more specifically the β-TCP. Although β-TCP has excellent bioactive and biocomp

30. Manufacturing and Characterization of Jute/PP Thermoplastic Commingled Composite
The commingled technology is a promising technique for the manufacture of composites reinforced with natural fibers. This study presents the development, processing and basic characterization of a long fiber Jute/Polypropylene (Jute/PP) commingled composite. The Jute/PP fabric was produced in a handloom and the composite was consolidated by compression moldi

31. Weldability Study of LM25/ZrO2 Composites by Using Friction Welding
ABSTRACT In this paper aluminum (LM25) alloy was chosen as a base matrix metal, and it was reinforced with 0, 3, 6, 9, 12% of Zirconium dioxide (ZrO2) particulates based on weight fraction method. Stir casting method was used to cast LM25/ZrO2 composite material. The cast samples were subjected to physical and mechanical test viz, density, hardness, tensile,

33. Fractographic and rheological characterizations of CF/PP-PE-copolymer composites tested in tensile
Abstract This work shows the fractographic study of fractured surfaces resulted from tensile tests of thermoplastic composites based on poly(propylene-co-ethylene) (PP-PE) and modified PP-PE copolymers reinforced with continuous carbon fibers (CF). The PP-PE matrix was modified with two agents called AM1 (based on maleic anhydride) and AM2 (containing an ela

35. Reinforcement of Polyester with Renewable Ramie Fibers
Ramie (Boehmeria nivea) fiber is one of several lignocellulosic fibers with superior strength, but the least investigated, particularly as reinforcement in strong, tough polymeric composites. This paper presents mechanical properties for polyester reinforced with aligned ramie fibers up to 30% by volume. It was found that adding 30 vol% of ramie fibers incre
