Fiber-reinforced polymer composites (FRCs) have shown great promise as high strength structural materials due to their high stiffness to weight ratio and their ease in processing. They have found extensive use in aerospace, automotive, construction, and recreational equipment material applications. Research in polymer-based nanocomposites (PNCs) has shown explosive growth in the past decade wit...

The paper presents review of research work experimental investigation on polypropylene fibre reinforced concrete and concrete with artificial sand. Use of fiber reinforce polymer in civil engineering increase rapidly. Various type of fiber is used such as glass, carbon, steel, asbestos, polyester and polypropylene. The various experimental investigations for determination of properties of polyp...

The objective of this research was to gain a better understanding of tensile properties of epoxy resin composites reinforced with glass fiber. The effect of fiber orientation & thickness of laminates has been investigated & experimentation was performed to determine property data for material specifications, the laminates were obtained by hand layup process. The laminates were cut to obtain AST...

Reinforced polymers have recently gained interest because of their high stiffness associated with the classical features and cost-effectiveness polymers. A further characteristic, suitable for several applications, is possibility to provide frictional wear resistance. The response commercially available reinforced materials was here investigated in a wide range contact boundary conditions. Expe...

Alpha-grass was studied as the reinforcement in a starch-based polymer matrix. Mater-bi®-Y was chosen as a matrix due to its Young’s modulus, in line with that of polypropylene. The test specimens were injection molded and tensile tested. The obtained results were compared to glass fiber reinforced polypropylene. The reinforcing fibers increased the Young’s modulus significantly, obtaining valu...

In tribological applications, because of the corrosive problems of the metals in water applications, poly-ether-ether-ketone (PEEK) and its composites are preferred for rubbing materials. As it is known PEEK is a high performance semi-crystalline thermoplastic polymer and has received significant attention in recent years. This is due to its high mechanical strength and elastic modulus, high to...

background: scuba diving is one of the fastest growing sports in the world. the objective of this study was to evaluate the effect of pressure variations to which divers are exposed on the pull out strength of glass fiber post luted with different cements. materials and methods: in this in vitro study, 120 extracted, single-rooted lower premolars were endodontically treated. they were randomly ...

Unmanned Aerial Vehicles (UAVs) have high popularity, especially in the military field, but are now also being applied to private and public sectors. One of UAV components that require material technology is wing. The latest developed as a for unmanned aircraft wings composite has strength lightweight. This research aims identify materials can be used wing structures. method this qualitative wi...

OBJECTIVES The aim of this study was to evaluate and compare the load-bearing capacity of fractured incisal edge of maxillary permanent central incisors restored with a nanocomposite and a glass fiber-reinforced nanocomposite. MATERIALS AND METHODS Thirty-six extracted sound maxillary central incisors randomly divided in three groups were used for the present study. Group I (control) containe...
