“…Among these materials, aramid-reinforced composites are known to have one of the best protection-to-weight ratios, high impact and compressive strength, and thus it is commonly applied in components subjected to impact loads, as well as in the lightweight armors production. [5][6][7] Among manufacturing techniques used to produce thermoset polymer composites, resin transfer molding (RTM) has become very popular in the automotive and aerospace sector industries. When compared to traditional compression and spray up techniques, RTM presents advantages, such as efficient processing, quick manufacturing cycles, good dimensional tolerance and surface finish in all sides and reduced costs.…”

“…10 For instance, some studies analyzed ballistic impact in thermoset polymer composites, 7,11-13 e.g. Omidvar et al 7 prepared epoxy/calcium carbonate/Kevlar (29/49 and 129) composites with epoxy resin. They achieved the best result with filling percentage of 50%, and highest thickness of 6 mm for the composite with Kevlar 49, it is considered as the best for rigidity and the results showed higher impact absorption.…”

This study focused on evaluating mechanical and dynamic-mechanical properties of polyaramid/vinyl ester composites, as a function of the fiber content. Furthermore, split Hopkinson pressure bar technique and V 50 Ballistic limit tests were performed. Composites were prepared by resin transfer molding (RTM) with different fiber content, samples being identified as AD4, AD5 and AD6 (with 4, 5 and 6 polyaramid layers, respectively). Initially, fiber, void and matrix contents were calculated and statistically analyzed, in different regions of the composites. Mechanical and dynamical mechanical properties of the composites were improved by using higher fiber content. For example, impact strength of AD6 composite was 35% higher than AD4. Moreover, increase in the fiber content promoted an increase in tenacity and stress of the composites, in the same strain rate. Velocity limit in AD6 sample was estimated in ballistics tests and it was concluded that the composite obtained could accomplish the level I requisites of ballistic protection with V 50 of 304 m.s À1 .

“…With regard to the mechanical behavior of the composite structures, different studies were used in the Taguchi method. In the study of Omidvar et al [17], the experimental method of Taguchi was used to find the relationship between different factors that control the optimal ballistic behavior in Kevlar-epoxy composite materials. Tom Sunny et al [18] used the Taguchi method for studied delamination in drilling GFRP composites.…”

The present study addresses the effect of attached mass on dynamic properties of composite laminate plates, under flexural vibration, for clamped-free-free-free boundary conditions. Furthermore, factors influencing the effect of attached mass on natural frequencies of laminate composite are studied using the Taguchi method. The considered factor parameters are: attached mass weight, attached mass locations from the clamped edge, staking sequences, and number of layers. The results of this study indicate that the dynamic characteristics of the laminate composite plates are sensitive to the attached mass, where the natural frequencies are found to be inversely proportional to the mass weight. The results was found that the locations of the attached mass and number of layers were the most important factors affecting the natural frequencies, where the location of the masses fell into the antinodes and into the nodal area of vibration, respectively. In addition, the paper presents a good correlation between the numerical results obtained by the ANSYS software and those obtained experimentally.

“…That is why a powerful simulator is needed to calculate the fuel consumption. This computer toolbox is able to define a specified vehicle to assess fuel consumption, exhaust products and useful performance characteristics (Wang et al 2012;(ADVISOR) AVS 2002;Markel et al 2002;Omidvar et al 2012).…”

Automotive emission is becoming a critical threat to today's human health. Many researchers are studying engine designs leading to less fuel consumption. Gearbox selection plays a key role in an engine design. In this study, Taguchi quality engineering method is employed, and optimum gear ratios in a five speed gear box is obtained. A table of various gear ratios is suggested by design of experiment techniques. Fuel consumption is calculated through simulating the corresponding combustion dynamics model. Using a 95 % confidence level, optimal parameter combinations are determined using the Taguchi method. The level of importance of the parameters on the fuel efficiency is resolved using the analysis of signal-to-noise ratio as well as analysis of variance.
