Research on static compression test of polyurethane foam/honeycomb paperboard composite material

Abstract

To study the mechanical behavior and energy absorption ability of polyurethane foam/honeycomb paperboard composite material under the static compression test. The static compression tests of polyurethane foam/honeycomb paperboard composite material are conducted by electronic universal testing machine. The mechanical behavior under the condition of static compression and the factors influencing the composite materials’ static cushioning properties were analyzed. Then, a comparison was made based on the energy absorption ability between composite materials and simple materials. The yield stress, strength and other indicators of foam/honeycomb paperboard have doubled the growth after filling polyurethane. The aperture size is the main influencing factor affecting the static cushioning properties of composite material. The energy absorption amount of composite materials is about 1.85 times than the total energy of two simple materials.
