background and aim: this study investigated the reinforcing effect of silica nanoparticles when incorporated into the matrix phase of an experimental dental fiber reinforced composites (frc) through the evaluation of the flexural properties of the composites. materials and methods: in this experimental study frc samples were divided into two main groups (containing two or three bundles) either ...

The compressive response of polymer matrix fiber reinforced unidirectional composites (PMC’s) is investigated via a combination of experiment and analysis. The study accounts for the nonlinear constitutive response of the polymer matrix material and examines the effect of fiber geometric imperfections, fiber mechanical properties and fiber volume fraction on the measured compressive strength an...

ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(pan)-based carbon fiber. the surface characteristics of carbon fibers were characterized by x-ray photoelectron spectroscopy (xps). the interfacial properties of carbon fiber reinforced polyamide 6 (cf/pa6) composites were investigated by means of the single fiber pull-out tests. as a result, it...

Background Fiber reinforced composite (FRC) is a promising class of material that gives clinicians alternative treatment options. There are many FRC products available in the market based on either glass or polyethylene fiber type. The aim of this study was to present a comparison between glass and polyethylene fiber reinforced composites based on available literature review. Material and Met...

The development of environmental friendly engineering material has received top priority recently. Glass fiber (GF) reinforced polypropylene (PP) composites is one of the most widely used materials in the automotive industry due to its favourable properties. However, the presence of GF has become a major issue in the recycling of GF/PP composites. Considerable efforts have been devoted to find ...

in this study, the strain rate effect on the bending properties of fiber reinforced composites for three types of polymer composites namely phenolic resin reinforced by woven basalt fibers, woven carbon fibers, and woven basalt/ woven carbon fibers at a total volume fraction of approximately 35% has been determined. flexural tests have been conducted at low range of strain rates included 0.03 m...

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...

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 ...

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...
