In this paper, Artificial Neural Network (ANN) has been used to predict the equivalent flexural strength of hybrid mesh and fiber reinforced cement-based composites (HMFRCBC). Three ANN models (Models 1, 2 and 3) were developed for predicting the flexural strength of cement-based composites. Model 1 used 48 data of the previously published data of the present authors and Model 2 used 48 data (o...

Polymer matrix composites used in different industrial applications due to their enhanced mechanical properties and lightweight. However, these materials are subjected to friction and wear situations in some industrial and automobile applications. Therefore, there is a need to investigate the wear properties of polymer matrix composite materials. This article emphasizes the dry abrasive wear be...

Abstract Background and Aim: One of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. Since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. Considering the diverse composition of avail...

The epoxy/glass fiber/organo-montmorillonite (OMMT) nanocomposites were prepared by hand lay up method. In the previous work, the flexural and morphological properties of the epoxy/glass fiber/OMMT were studied. In this work, the epoxy nanocomposites were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and water absorption tests. The exfoliation of OMMT in epox...

The purpose of this study is to review many of the available guidelines for Polymer composite materials. Guide lines for failure mode, laminates orientation, winding angle, water absorption, as they strongly influence the mechanical properties of composite materials. The present review is focused on composite laminates made of glass, carbon, graphite, hybrid and natural fiber composites, since ...

Two novel mathematical models based on polynomial function (PF) and boundary condition method (BCM) are presented for determination of shear stress in interface in steady state creep in short fiber composites under axial loading. Important novelty of this research is determination of shear stress in interface without using of shear lag and imaginary fiber technique (IFT) theories. In these appr...

In this work, we report the potential use of novel carbon nanofibers (CNFs), dispersed during fabrication of glass fiber composites to monitor damage propagation under static loading. The use of CNFs enables a transformation of the typically non-conductive glass fiber composites into new fiber composites with appreciable electrical conductivity. The percolation limit of CNFs/epoxy nanocomposite...

in this study, the disadvantages of wood, which is widely employed in producing music instruments, are discussed. for example, high moisture sensitivity, low impact resistance, and time-consuming procedure as well as various properties of different species or in several parts of one specimen which are the main problems of wooden music instruments are extensively discussed in this paper. many ma...

Life cycle assessment is a technique to assess environmental aspects associated with a product or process by identifying energy, materials, and emissions over its life cycle. The energy analysis includes four stages of a life cycle: material production phase, manufacturing phase, use phase, and end-of-life phase. In this study, the life cycle energy of fiber-reinforced composites manufactured b...

In this research, creation of higher mechanical natural fiber mat composites was proposed. The hybrid mat with jute and glass mat was fabricated by needle punching system, in which jute mat was placed on glass mat. The ratio of jute and glass mat layers was set to be 1:0,1:1,1:2 and 2:1, respectively. The composites were fabricated by hand-lay up method with unsaturated polyester resin after ne...
