Prediction Model for Compressive Strength Value of Aluminum Honeycomb Materials Joined with %1 MWCNT Reinforced Epoxy Adhesive

Abstract

Accepted: 12.03.2015 In this study, aluminum(Al.) honeycomb composite structures were produced by joining core of different cell width and cell height to lower-upper layers by 1% multiwall carbon nanotube reinforced(mwcnt) epoxy adhesive. Compressive strength experiments of Al. honeycomb structures were carried out according to ASTM C365 standards using Instron 8081 model pulling device. Compressive strength values (F) are measured. Compressive experiments were performed three times and mean values were calculated. Experimental results shows that compressive force values decrease when cell height is increased while cell width is constant and values increase when height is decreased. When experimental result is analyzed for the same cell height, it is seen that compressive force values decrease while cell width increases and values increase when cell width decreases. Multiple regression prediction model of strength values of Al. composite structure was created using MINITAB14 programme. Logarithmic regression results of multiple regression prediction models were consistent with the results of the experiment with a coefficient of determination of 97.7%.
