Research on Static Compression Test of Polyurethane Foam/Honeycomb Paperboard Composite Material

Objective: To study the mechanical behavior and energy absorption ability in the static compression test of polyurethane foam/Honeycomb paperboard composite material. Methods: The static compression test of polyurethane foam/honeycomb paperboard composite material are conducted by electronic universal testing machine. The mechanical behavior under the conditions of static compression and the influence factors of composite material static cushioning properties were analyzed. Then, a comparison was made between composite materials and simple materials in the respect of the energy absorption ability. Results: The yield stress, strength and other indicators of foam/honeycomb paperboard have doubled growth after filling polyurethane. The aperture size is the main influence factor of static cushioning properties of composite material. Conclusion: The energy absorption amount of composite materials is about 1.85 times than the total energy of two simple materials.
