The incorporation of inorganic nanoparticles with thermosetting epoxy polymer is an emerging field research over the past few years. It well analyzed that matrix brittle in nature shows rapid crack initiation and propagation without increasing applied stress value. Therefore, researchers are showing their interest embedded composites to improve fracture resistance (brittleness toughness). In th...

The response over the low-velocity impact of various shape impactors on a glass fiber reinforced polymer composite has been numerically analyzed with hemispherical, flat, partially flat and truncated shaped impactor used to analyze behavior resistance GFRP at speeds. numerical analysis was carried out using finite element software, ABAQUS (Dynamic/Explicit). To assess laminates while impacting,...

Impact tests were carried out on composite laminates and composite scarf repairs, while both were subjected to in-plane loading with tensile pre-strain levels up to 5000 microstrain. The results show that pre-straining of the composite laminates has no noticeable influence on the size of the delamination area for the given impact energy of 8 J, which represents a typical barely-visible impact o...

The glass-reinforced laminated composite is widely used in place of conventional structural materials. glass fiber composites demonstrate outstanding strength the uniaxial direction. effect carbon nanotube reinforcement percentage on flexural polymer investigated this article. final laminates has been found to improve by reinforcing Carbon nanotube. small incorporation MWCNT improves up 51.3%. ...

Automobile sector is always focusing on enhancing level of comfort, fuel economy, customer satisfaction and safety. Vehicle weight reduction increases the overall fuel efficiency. Use of composite materials has made it possible to reduce the weight of the vehicle, without reduction in load carrying capacity. Now a day's manufacturers and researchers are trying to replace conventional material p...

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 ...

In this paper, the problem of tensile strength prediction of composite laminates containing artificially implanted holes is confronted. An approach based on the integration of acoustic emission and load data through neural network is presented. The obtained results show that neural networks can be a useful tool in the monitoring of fracture behavior of composite laminates through acoustic emiss...
