This paper presents a numerical modelling methodology to investigate the thermo-mechanics of carbon reinforced thermoplastic-based laminates in situation mechanical loading combined thermal gradients. It concerns particular case irradiation on one face laminate, where temperature varies both from point laminate and through time, ranges ambient matrix decomposition onset. Temperature is key vari...

Use of direct composite and indirect laminate veneers has been an alternative to metal- and all-ceramic crowns for anterior teeth restorations. Dental traumas are the most common reasons for excessive tissue loss. Treatment options depend on the amount of remaining tissue, the extent of the damage to dental pulp and periapical tissues and the time elapsed before dental treatment. The aim of thi...

(ABSTRACT) Composite panel structure optimization is commonly decomposed into panel optimization subproblems, with specified local loads, resulting in manufacturing incompatibilities between adjacent panel designs. Using genetic algorithms to optimize local panel stacking sequences allows panel populations of stacking sequences to evolve in parallel and send migrants to adjacent panels, so as t...

(Abstract) Genetic algorithms are well known for being expensive optimization tools, especially if the cost for the analysis of each individual design is high. In the past few years, significant effort has been put forth in addressing the high computational cost GAs. The research conducted in the first part of this thesis continues this effort by implementing new multiple elitist and variable e...

In this paper Knowledge Discovery System (KDS) is proposed and implemented for the extraction of knowledge-mean stiffness of a polymer composite material in which when fibers are placed at different orientations. Cosine amplitude method is implemented for retrieving compatible polymer matrix and reinforcement fiber, which is coming under predicted fiber class, from the polymer and reinforcement...

Abstract Low mechanical resistance and high weight restrict use of natural stones in applications where tensile or flexural capacity is required together with a low weight, such as for long spans or thin sections (e.g., cladding, countertops, desktops). The use of composite laminates as external reinforcement both to increase the mechanical resistance and to decrease weight of natural stone is ...

Thermophysical properties of a carbon-reinforced epoxy composite laminate (T700/M21 composite for aircraft structures) were evaluated using different innovative characterisation methods. Thermogravimetric Analysis (TGA), Simultaneous Thermal analysis (STA), Laser Flash analysis (LFA), and Fourier Transform Infrared (FTIR) analysis were used for measuring the thermal decomposition, the specific ...

Hybrid fibre reinforced polymer (FRP)-timber (HFT) thin-walled structural members made out of thin-timber veneer and composite laminates are a sustainable alternative to light-weight steel aluminium members. Preliminary studies on HFT structures have demonstrated the potential be used as high performing This study is aimed at investigating effect manufacturing pressure type mechanical propertie...
