Abstract

The needs of the human communities and industry to build low weight, high strength and durable structures have increased the demand for composite materials, including sandwich structures. In this case sandwich panels are used in situations requiring high mechanical strength, low weight, sound insulation and thermal insulation properties. In this study, Carbon Nanotubes-reinforced composite Honeycomb sandwich panels, were constructed using silicone molding. To determine the role of Carbon Nanotubes on the compressive and bending behavior of sandwich panels, a different weight percentage of this material (0/025, 0/05. 0/075) was added to the epoxy resin. Also, different thicknesses (5mm, 2/5mm) were tested to determine the role of core wall thickness on the compressive and bending behavior of sandwich panels. The results showed that the Compressive Strength of Honeycomb panels has a direct relation with the increase in the percentage of Carbon Nanotubes and also the thickness of the wall. The Compressive Strength of Sandwich panels increased from 42/06 up to 54/32 MPa with increasing carbon from 0/025 up to 0/075 nanotubes. The Compressive Strength of sandwich panels with 5 mm Honeycomb wall thickness and reinforced with 0/025, 0/05 and 0/075 weight percent of Carbon Nanotubes compared to sandwich panels with 2. 5 mm Honeycomb wall thickness were respectively 2/38, 2/15 and 2. 17 times. also the Flexural Strength of 5-mm Honeycomb wall thickness and reinforced with 025/0, 0/05 and 0. 075% weight percent of Carbon Nanotubes compared to sandwich panels with 2. 5 mm Honeycomb wall thickness, were respectively 3, 2. 66 and 2. 7 times.
