Mechanical strength evaluation of poly(methyl methacrylate) reinforced with long glass, carbon and aramid fibers

Abstract

The purpose of the study was the comparison of poly(methyl methacrylate) reinforced with different types of long fibers: glass, carbon, aramid, glass-aramid hybrid and carbon-aramid hybrid fibers. The test material included 48 samples in the form of a cuboid. The strength tests were performed using the Zwick 1435 machine. The highest strength increase in relation to control samples was obtained with the use of aramid fibers and the lowest with the use of glass fibers.

Effect of Graphene Oxide Incorporation on the Strength of Denture Repair Resin

“…They are light, economical, and aesthetic materials. [1][2][3][4][5] However, the lack of sufficiently developed mechanical strength increases the risk of fracture. 2,6 Materials used in fracture repair should have properties such as being economical, compatible with the color of the dentures, polymerizing quickly, being simple, having sufficient strength, and maintaining dimensional stability.…”

“…7 To overcome these disadvantages, it is aimed at improving the properties of acrylic by adding materials such as glass fiber mesh, cobalt-chromium-nickel, fiber (glass, carbon, aramid, etc), stainless steel, silver, titanium, or zirconium oxide nanoparticles. [2][3][4][5]8 In recent years, graphene and its derivatives have been used to improve the mechanical and biological properties of polymers. 2,9,10 Graphene is a crystalline form of carbon.…”

Statistical inferences in material selection of a polymer matrix for natural fiber composites

“…However, the poor dimensional stability and high mois ture absorption become a problem to these materials [14]. There are many treatments that can increase the strength connection between the natural fiber and polymer ma trix [15][16][17][18][19] to produce a valuable polymer composite, es pecially in the automotive industry. Generally, thermo plastic (Tp) and thermoset (Ts) materials are the polymers used in many applications.…”
