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...

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...

A Portland cement plaster wall system has many positive features, but one of the physical properties that it does not possess is flexural strength. It is because of the inability of the Portland cement plaster membrane to bend or flex that glass fiber strands were used in Portland cementbased plaster. There are various types of synthetic fibers on the market that will provide flexural strength ...

Abstract In this study, the mechanical damage of Basalt/E-glass hybrid fiber-reinforced polymer composite tubes was evaluated experimentally using Micro hardness on transverse direction, uni-directional static tensile loading, and Quasi-static compressive loading. The Burn-off test method has been studied for volumetric fraction tubes. multi-layer composed eight layers plies at constant fiber t...

The glass fiber reinforced epoxy resin composites play an important role in superconducting Tokamak, which are used to insulate the metal components, such as superconducting winding, cooling pipes, metal electrodes and so on. For the components made of metal and glass fiber reinforced epoxy resin composites, thermal shrinkage leads to non-ignorable thermal stress, therefore, much attention shou...

Abstract The purpose of this research is to understand the transient fiber orientation and the associated rheology of long glass fiber (> 1mm) reinforced polypropylene, in a well-defined simple shear flow, to extend the results and knowledge gained from these fundamental experiments to the use of simulating (more complex) molding processes. Specifically, we are interested in associating the rhe...

Composite resins were reinforced with glass and polyethylene fibers in this study, and the effect of fiber reinforcement on the color change of composite resins was investigated. After accelerated aging, the effect of fiber reinforcement on the color stability of composite resins was also examined. There were three experimental groups (n=12 disks per group): non-fiber-reinforced composite (non-...

INTRODUCTION Along with the miniaturization of optical devices such as medical endoscopes and fiber-optic communication systems, micro-aspheric lenses (1 mm in diameter) have become very important parts [1]. Micro-aspheric lenses are necessary for downsizing and higher image quality. Form accuracy of micro-aspheric lenses is required to be better than 100 nm to make the most of those devises. H...

background : denture fracture is an unresolved problem in complete denture prosthodontics. however, the repaired denture often experiences a refracture at the repaired site due to poor transverse strength. hence, this study was conducted to evaluate the effect of joint surface contoursand glass fiber reinforcement on the transverse strength of repaired acrylic resins. materials and methods: a t...

This study investigated the flexural strength of eight fiber posts (one carbon fiber, one carbon/quartz fiber, one opaque quartz fiber, two translucent quartz fiber, and three glass fiber posts). Eighty fiber posts were used and divided into eight groups (n = 10): G1: C-POST (Bisco); G2: AESTHETI-POST (Bisco); G3: AESTHETI-PLUS (Bisco); G4: LIGHT-POST (Bisco); G5: D.T. LIGHT-POST (Bisco); G6: P...
