Fabrication and flexural experimentation of composite sandwich beams with metal facesheets

This study investigates the bending response of the sandwich composite beam that has undergone three-point bending. The sandwich composite consists of a Unifoam Polystyrene core sandwiched between two aluminum facesheets. This project will be going through the fabrication process of the sandwich com...

This project will be going through the fabrication process of the sandwich composite beam, experimental set-up for testing various specimens, and experimental results of the three-point bending test and compression test.

Next, the sandwich composite beam undergoes 3-point bending until failure to study its bending behavior, the beam fails by core indentation due to localized force. Therefore, a compression test is conducted on the unifoam core to obtain its compressive behavior and understand the different phases of compression.
