Among numerous types of health-monitoring and damage-sensing sensors that can be integrated into composites, electrically conductive sensors offer a simple, cost-effective, and durable option for structural health monitoring in fiber reinforced composites. In this study, a novel approach is introduced to create electrical conductive networks in glass fiber reinforced composites. For this purpose, hollow micro-channels are generated using vaporization of sacrificial components (VaSCs) which are subsequently filled with CNT-epoxy conductive fillers to induce conductive pathways within the composite. The presence of vascular conductive pathways was not found to hinder the structural integrity of the composites. The use of such conductive pathways for in situ strain monitoring of composites was investigated. The strain sensitivity of the prepared conductive pathways in the composite were found more than twice that of conventional strain sensors, rendering such conductive pathways a promising alternative for in-situ strain monitoring of continuous fiber-reinforced composites.

A procedure to embed fibre Bragg grating strain sensors into GFRP sandwich structures
Dawood, T. A.; Shenoi, R. A.; Şahin, Melin (Elsevier BV, 2007-01-01)
Embedding FBG strain sensors within a GFRP sandwich composite material allows early detection of internal defects. However, the sensors need to survive the manufacturing process to provide this capability. Vacuum infusion is commonly used to manufacture GFRP sandwich composite materials but, it needs to be modified to accommodate the embedding process. A stage by stage procedure is demonstrated here to embed FBG strain sensors between the skin-core interface of a GFRP sandwich beam specimen using the vacuum...
An Approach for the Evaluation of Effective Elastic Properties of Honeycomb Cores by Finite Element Analysis of Sandwich Panels
Aydincak, Ilke; Kayran, Altan (SAGE Publications, 2009-09-01)
Different detailed finite element model alternatives are developed to come up with the most reliable finite element model of the sandwich panel, with the actual honeycomb core geometry, to evaluate the existing equivalent continuum models of aluminum honeycomb cores. Finite element models of sandwich panels with effective elastic constants of the honeycomb core are generated based on the existing continuum models of the honeycomb core. The evaluation of the effective elastic constants of honeycomb cores is ...
Design of fiber-reinforced composite pressure vessels under various loading conditions
Levend, P; Katirci, N (Elsevier BV, 2002-10-01)
An analytical procedure is developed to design and predict the behavior of fiber reinforced composite pressure vessels. The classical lamination theory and generalized plane strain model is used in the formulation of the elasticity problem. Internal pressure, axial force and body force due to rotation in addition to temperature and moisture variation throughout the body are considered. Some 3D failure theories are applied to obtain the optimum values for the winding angle, burst pressure, maximum axial forc...
Design and analysis of filament wound composite tubes
Balya, Bora; Parnas, Kemal Levend; Department of Mechanical Engineering (2004)
This thesis is for the investigation of the design and analysis processes of filament wound composite tubes under combined loading. The problem is studied by using a computational tool based on the Finite Element Method (FEM). Filament wound tubes are modeled as multi layered orthotropic tubes. Several analyses are performed on layered orthotropic tubes by using FEM. Results of the FEM are examined in order to investigate characteristics of filament wound tubes under different combined loading conditions. W...
Contribution of carbon nanotubes to vibration damping behavior of epoxy and its carbon fiber composites
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...
