Foaming composites were prepared by using the starch and EVA as the main ingredients, supplemented with glycerol, NaHCO3, wood powder additives and mould pressing through flat vulcanizing machine. Through the analysis of the static compression property, cushioning property of the composite foam was mainly studied with the influence of contents of starch, glycerin, NaHCO3 on the performance of cushioning property. The research showed that with the increase in starch content, the cushioning property of composite material was improved. The cushioning property was best when starch content was 55%. Adding Glycerin could increase the flexibility of the compound foam material. The cushioning property reached optimal when glycerin content was 14%. NaHCO3 content exerted major effects on cushioning property, and the cushioning property was optimal when NaHCO3 content was 9%.
