目的 为减少对化石燃料的广泛依赖，用生物质复合材料替代合成纤维增强复合材料，制备轻质、缓冲等高性能天然纤维复合材料，开辟环境新材料领域创新的方向。方法 通过不同种类生物质填充物及配比变化，一步成型制备一种可降解轻质发泡缓冲材料，研究缓冲材料产品缓冲性能。结果 相同填充比例条件下，玉米秸秆发泡体缓冲性能优于汉麻秆芯材料;相同填充物条件下，填充比例为30%～40%，缓冲性能良好。结论 为各行业应用提供了环境友好的替代性结构产品，扩展了复合材料应用范围，尤其研发成本低、性能好的生物质复合材料具有重要战略意义。

With biomass pulp as the main raw material and various biomass waste fibers as fillers, a degradable lightweight foaming buffer material was prepared by one-step molding with abundant biomass resources by adopting physical turbulent mechanical mixing method. Through different kinds of biomass fillers and ratio changes, the changing relationship of cushioning properties of cushioning materials products was studied. The results show that the cushioning performance of corn straw foam is better than that of hemp core material under the same filling ratio. Under same filling condition, the filling ratio is 30%-40%, and the buffer performance is good. This material is of great significance for exploring the use of biomass waste to develop new environmental protection packaging materials instead of foam plastic products and then providing reference for industrial application.
