The aim of this study was to investigate processing parameters of continuous fiber reinforced epoxy composite tubes produced by the filament winding technique. For this purpose, split-disk tests (according to ASTM D-2290 standard) were performed for the specimens produced with two different epoxy resin systems, five different fiber materials and five different winding angles. By determining the hoop tensile strength and modulus of these specimens, the effects of three filament-winding processing parameters; resin type, fiber type and winding angle were evaluated. It is found that use of different epoxy resin systems has no significant influences, while use of carbon fibers compared to glass fibers and use of winding angles greater than 60 degrees increase the performance of the structures considerably. It is also concluded that split-disk tests are efficient to determine the performance of these tubular structures which are usually used under internal pressure developing high hoop stresses.

Cansever, Cahit Can; Yılmazer, Ülkü; Department of Polymer Science and Technology (2007)
In this study, effect of injection molding process parameters on fiber length and on mechanical properties of Polyamide-6 / glass fiber composite were investigated to produce higher performance composites. Polyamide-6 was first compounded with an E-grade glass fiber in a co-rotating intermeshing twin screw extruder. Then, by using this composite, twenty-five types of experiments were performed by injection molding by changing the barrel temperature, injection pressure, hold pressure, mold temperature, cooli...
Behavior of steel-concrete partially composite beams with channel type shear connectors
Baran, Eray; Topkaya, Cem (2014-06-01)
This paper summarizes the findings of an experimental study investigating the flexural behavior of partially composite beams incorporating channel type shear connectors. Results from monotonic load testing of four full-scale steel-concrete composite beams and a steel beam are presented. The main effort focused on identifying the variation of strength and stiffness properties of beams with various degrees of partial composite action. Behavior of channel shear connectors in the composite beam specimens is rel...
A hybrid uniform geometrical theory of diffraction-moment method for efficient analysis of electromagnetic radiation/scattering from large finite planar arrays
Aydın Çivi, Hatice Özlem; Chou, HT; Nepa, P (2000-03-01)
A hybrid uniform geometrical theory of diffraction (UTD)-moment method (MOM) approach is introduced to provide an efficient analysis of the electromagnetic radiation/scattering from electrically large, finite, planar periodic arrays. This study is motivated by the fact that conventional numerical methods become rapidly inefficient and even intractable for the analysis of electrically large arrays containing many antenna or frequency-selective surface (FSS) elements. In the present hybrid UTD-MOM approach, t...

Avil, Esma; Kadioglu, Ferhat; Kaynak, Cevdet (SAGE Publications, 2020-04-01)
The main objective of this study was to investigate contribution of the non-functionalized multi-walled carbon nanotubes on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber reinforced epoxy matrix composites. Epoxy/carbon nanotubes nanocomposites were produced by ultrasonic solution mixing method, while the continuous carbon fiber reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the...
