The Application of Statistical Design of Experiments to Study the In-Plane Shear Behaviour of Hybrid Composite Sandwich Panel
Abstract: This paper presents
a statistical aspect of experimental study on the in-plane shear behaviour of
hybrid composite sandwich panel with intermediate layer. The study was aimed at
providing information of how significant the contribution of intermediate layer
to the in-plane shear behaviour of new developed sandwich panel. The
investigation was designed as a single factor experimental design and the
results were throughly analysed with statistics software; Minitab 15. The
panels were tested by applying a tensile force along the diagonal of the test
frame simulating pure shear using a 100 kN MTS servo-hydraulic UTM. The result
shows that the incorporation of intermediate layer has sinificantly enhanced
the in-plane shear behaviour of hybrid composite sandwich panel. The
statistical analysis shows that the value of F0 is much higher than the value
of Ftable, which has a meaning that the improvement provided by the
incorporation of intermediate layer is statistically significant.
