Fiber reinforced composite (FRC) posts are commonly used by clinicians in post-endodontic restorations, mostly due to their favorable physical properties, i.e. the modulus of elasticity close to that of dentin (1). Yet, clinical failures involving endodontically treated teeth reconstructed with FRC posts could occur and are mainly attributed to cementation flaws (2). The design and composition ...

Adhesively luted, fiber-reinforced, composite-inlay, retained fixed-partial dentures can be a clinical alternative for the replacement of missing posterior teeth in selective situations. This type of restoration allows for satisfactory esthetics and reduced tooth preparation compared to a conventional, fixed-partial denture. This clinical report describes the use of a fiber-reinforced, composit...

In this paper the effect of various chemical treatments on the damping property of jute fiber reinforced green composite is discussed. The surface of the jute fiber was modified by alkali, permanganate, benzoyl chloride, malic anhydride and silane treatments. Several samples of unidirectional composites were prepared with treated jute fibers as well as untreated jute fibers. Matrix used is epox...

OBJECTIVES The aim of this study was to investigate the effects of fiber-reinforced resin burs on the surface roughness of a nanofilled composite. METHODS Average surface roughness values (Ra, mum) were measured using a surface profilometer and surface textures after finishing procedures were evaluated using a scanning electron microscope (SEM). Thirty cylindrical specimens were prepared usin...

Glass fiber reinforced polymer composites are one of the most widely used composite materials. The addition of Coal ash to polymer matrix dramatically increases the overall mechanical strength of the composite material as compared to the polymer composite. In view of this, a method is proposed for mixing coal ash powder (size 52-75 μm) into resin and Ash reinforced polymer composites are fabric...

Recently, short fiber reinforced composites are widely utilized in many structural parts in automobile, infrastructure and electric equipment applications due to their high specific strength, high specific stiffness, long fatigue life and high impact resistance as well as cost effective capability of production. If these parts are exposed to low-velocity impact, significant damages may develop ...

Interlaminar shear strength (ILSS) of fiber reinforced polymer composite is an important property for most of the structural applications. Matrix modification is an effective method used to improve the interlaminar shear strength of composite. In this paper, EPON 862/w epoxy system was modified using Tetraethyl orthosilicate (TEOS) electrospun nanofibers (ENFs) which were produced using electro...

The mechanical characterization of short E- glass fiber reinforced, graphite and sintered bronze filled epoxy composite was carried out in this study. The aim of the present study was to develop tribological engineering material. In this study the flexural strength, theoretical and experimental density, Hardness and Impact strength of composites was investigated experimentally. The results show...
