Quasi - static and dynamic mechanical properties of honeycomb reinforced plastic foam

Honeycomb reinforced plastic foam samples were prepared through honeycomb cutting and injection molding process, and the compression tests of samples were done. Through tests the pressure-displacement date were obtained, then the calculation was conducted to obtain the stress-strain curve of honeycomb reinforced plastic foam samples. The experimental results show that stress of all honeycomb reinforced plastic foam samples is larger than the sum of honeycomb and plastic foam. It is also found that the complex effect of composite material is more apparent with the decrease of the length of the cell and the increase of the thickness of samples. On the basis of quasi-static properties, the simulation model of composite material was built. By applying pressure pulse to the model, the same complex effect was found on the condition of dynamic impact. It is proved that this composite material is suitable not only for lower strain ratio, but also for higher strain ratio.
