Thermal non-destructive testing and evaluation of glass fibre reinforced plastic materials has gained more importance in aerospace industry due to low weight and high strength capabilities in severe environmental conditions. More recently, pulse compression favorable non-stationary excitation schemes have been exhibiting reliable defect detection capabilities in infrared non-destructive testing...

The flexural strength comparasion of epoxy matrix composite with diferent reinforcement . Composite is a combination two or more materials that have good physical properties and mechanical properties. Reinforcement commonly used in polymer composites are fibers strips material, bamboo fiber,carbon, PALF malva fiber as resin matrix. research phase began finding the journal which explain about us...

AIM AND OBJECTIVES Use of posts improves the physical properties of endodontically-treated teeth. Different post types are developed such as metal, custom-made, carbon, and quartz. The present study was conducted to evaluate the fracture resistance of glass fiber-reinforced, carbon, and quartz post in endodontically-treated teeth. MATERIALS AND METHODS Forty extracted human maxillary incisor ...

Carbon fiber reinforced polymer (CFRP) sheets are externally bonded to reinforced concrete (RC) members to provide additional strength such as flexural, shear, etc. It has been widely accepted that carbon fiber reinforced polymers (CFRPs) can be used effectively to strengthen reinforced concrete (RC) members. This paper is intended to study and use externally bonded CFRP strips to repair and st...

Abstract The mechanical properties of carbon fiber-reinforced epoxy composites were identified by adding carbon-based nano-reinforcements, such as multi-wall nanotubes (CNTs) and graphene platelets (GP), into the matrix conducting suitable experiments. main focus this study is to compare tensile modulus, strength, flexural thermal conductivity with nanoparticle reinforcement. results revealed t...

in this paper deflection and free vibration of sandwich panel is studied. the core of sandwich panels is made of hexagonal honeycomb and faces are made of two different materials of carbon fiber reinforced plastic and k-aryl/epoxy covering. the governing equations are deduced from the first order sheer deformation theory (fsdt) and they are solved using generalized differential quadrature metho...

Reliable failure prediction methods are required for extending the range of applications of carbon-fiber-reinforced-polymers. In parallel, the development of non-destructive tests (NDT) for continuous health monitoring would result in structures of improved durability and safety. Carbon fibre-reinforced polymers (CFRP) have been investigated for the development of “smart” structures characteriz...

The properties of chloride penetration of hybrid fiber reinforced self-compacting concrete (SCC) were investigated in this study. The results show that the chloride penetration resistance of concrete can be improved by single incorporation either carbon or cellulose fibers. The concrete chloride diffusion coefficient DRCM of 12-cm length carbon SCC with fiber content of 1.7, 2.72, and 3.4 kg/m3...

The article presents the methodology for finding material damping properties at higher frequency and at relatively lower amplitudes. The method employs combined Finite element and frequency response for finding the damping characteristics of composite materials, which are used in high frequency applications. The hybrid method has been implemented on carbon fiber reinforced polymer (CFRP) and gl...
