The paper presents the initial results of the epoxy-glass composite samples analyses carried out with the use of terahertz spectroscopy. Firstly, the standard specimens made of epoxy resin and glass fibers were researched. The first sample consisted of one layer of glass fiber, the second one had two such layers. To compare the results the results of the composite material sample shut with the ...
The objective of this study is to develop a multiscale modeling approach to predict the influence of molecular structure and microstructure on the bulk-level properties of a graphite/epoxy plain-woven fabric composite in which the resin-rich regions are reinforced with carbon nanotubes. The modeling approach incorporates molecular modeling and micromechanics techniques. A parametric study shows...
This work presents an insight into the effect of conductive filler content on both electrical and thermal properties of a polymer composite system. The electrical conductivity of an insulating polymer can be achieved by dispersing conducting fillers (e.g., metal, graphite powder, carbon black, carbon fiber) in the polymer matrix. The resulting materials are referred to as conducting polymer com...
Inspired by biological systems in which damage triggers an autonomic healing response, we have developed a polymer composite material that can heal itself when cracked. This paper summarizes the self-healing concept for polymeric composite materials and investigates fracture mechanics issues consequential to the development and optimization of this new class of materials. The self-healing mater...
Interlaminar shear strength (ILSS) of fiber reinforced polymer composite is an important property for most of the structural applications. Matrix modification is an effective method used to improve the interlaminar shear strength of composite. In this paper, EPON 862/w epoxy system was modified using Tetraethyl orthosilicate (TEOS) electrospun nanofibers (ENFs) which were produced using electro...
This research investigates the effect of post-cure time on residual stresses in laminated composites. Laminated composites were made of T300 carbon fibers and epoxy resin. The post-cure process was carried out at the constant temperature of 120 °C for 6 and 12 hours for two specimens. The slitting method was employed to determine through-thickness residual stress distribution of the composite l...
imperialist competitive algorithm (ica) is a new socio-politically motivated global search strategy. the ica is applied to hybrid composite laminates to obtain minimum weight and cost. the approach which is chosen for conducting the multi-objective optimization was the weighted sum method (wsm). the hybrid composite laminates are made of glass/epoxy and carbon/epoxy to combine the lightness and...
