The fibre composites are special materials consisting of unique properties such as high specific strength, high specific stiffness, corrosion resistance, high fatigue life etc. They have immense potential to replace the traditionally utilised materials, steel and aluminium for manufacturing of various components of vehicles which renders them very heavy and bulky. This paper demonstrates the feasibility of producing innovative alternative lighter composite materials using E-glass for increasing the safety, movability, performance of the military vehicles. Five different composites were synthesis without fillers and with 4% ZnO, SiO, carbon black and hybrid fillers using hand layup technique. Various mechanical tests such as tension, compression, flexural, inter laminar shear, impact and hardness test were performed on the composites to evaluate and analyse their mechanical properties for exploration of their effective utilisation in automobiles. The study determined that the composite with ZnO filler manifested superlative behaviour in comparison to other materials under examination.

In this paper, we report a modelling investigation of the thermoluminescence mechanisms for the important dosimetric LaAlO3:C crystals, which were grown by solid state reaction method. The aim of this work is to develop for the first time an algorithm that permits the numerical solution of the relevant sets of differential equations governing the different stages of the experimental procedure. The glow curve measured at 10K/s typically consists of three prominent peaks at 417 K, 494 K and 549 K and a minor glow peak at around 372 K. In this work, we show that this TL output behaviour can rather easily be explained within the framework of the 4T1R model. Good agreement between the experimental data and calculations from the model is obtained for this kind of dosimetric material. Results presented here confirm that the LaAlO3:C system an excellent candidate that can be used as a TL dosimeter in UV fields.

The effect of dispersion of fillers in different weight percentages on structural, electrical, and humidity sensing properties of polymer matrix has been investigated. Cerium-aluminate (ACO) was used as the filler material in the polypyrrole (PPy), and the dispersion of the filler was done by an in-situ chemical-polymerisation method. The nanocomposites were characterised by various techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDAX), Fourier transform infrared (FTIR) and thermogravimetry/differential thermal analysis (TG/DTA). The room temperature electrical characterisations were carried out which showed that the lower (10 wt.% and 20 wt.%) and higher (30 wt.%, 40 wt.% and 50 wt.%) filler contents in nanocomposites make them behave like dielectrics and conductors respectively. The AC-conductivity of the PPy was decreased for 10 and 20 wt.% whereas increased for the higher wt.%. The humidity response was studied by using an impedance-analyser, which shows the improvement in sensing properties.

The presence of tetragonal distortion and spontaneous polarisation in lead titanate attracts the researchers to modify the titanate perovskites. A modified lead titanate Pb(Cd1/3W1/3Ti1/3)O3 perovskite is synthesised by a conventional high-temperature solid-state reaction technique. XRD pattern of the sample confirms the cubic crystal structure having space group F-43m. Full proof Rietveld analysis has been used for structural refinement. The presence of FTIR frequency bands corresponding to Ti-O, O-, W-O-W, and CdO stretching confirm that Cd2+, W6+ ions completely substitute the Ti+4 ions at the B site of the perovskite, as confirmed by the XRD obtained data. As the frequency increases from 1 kHz to 5 MHz, the activation energy (Ea) decreases from 0.767 eV to 0.089 eV. The activation energy and conductivity mechanism in the samples dominated by hopping charge carriers. Both Nyquist and Cole-Cole plots confirm the semiconducting nature of the samples and make the material technologically important.
