Carbon nanotubes (CNTs) are being investigated as a means for large-scale inspection of composite structures. Several studies have shown that CNTs possess exceptional mechanical stiffness and strength, as well as excellent electrical conductivity and piezoresistivity. Thus, it has been proposed that CNTs could be used not only to reinforce composite structures for improved impact and delaminati...

Problem statement: This study presents the results of ANFIS based model proposed for predicting the performance characteristics of reinforced HSC beams subjected to different levels of corrosion damage and strengthened with externally bonded glass fibre reinforced polymer laminates. Approach: A total of 21 beams specimens of size 150, 250×3000 mm were cast and tested. Results: Out of the 21 spe...

The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite el...

This research paper compares the thermal conductivity and thermal expansion coefficients of glass fiber reinforced epoxy composite laminates (GFRP laminates) made using the Hand layup technique. The composite laminates were fabricated by filling with varying concentrations of fly ash, stone powder, aluminium oxide (Al2O3), magnesium hydroxide (Mg (OH)2), Silicon carbide particles(SiC) and hemat...

Delamination is the main defect form of composite laminates. The strength and stiffness laminates are greatly decreased due to delamination defects. In this paper, FE model with was established. And nonlinear post-buckling response investigated. validity verified by comparing analysis results experimental results. a detailed parametric study performed on effects planimetric position behavior Re...

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...
