Development of nano cellulose fiber green composites fabricated by combining controlled solidification and freeze-drying

本课题制备了纳米纤维素纤维与热塑性树脂或热固性树脂组成的绿色复合材料，并通过实验考察了工艺条件对其力学性能的影响。与纯树脂相比，制得的绿色复合材料的变形应力、最大强度和杨氏模量均有所提高。从实验结果可以看出，利用该方法可以获得高强度的绿色复合材料。

In this project, the green composites which are composed of cellulose nano fiber and thermoplastic resin or thermosetting resin were fabricated, and the effects of processing conditions on their mechanical behavior were examined experimentally. Their deformation stresses, maximum strength and Young's modulus of the fabricated green composite materials increased in comparison with those of the neat resin. It can be seen from the experimental results that it is possible to obtain high-strength green composite by using the proposed method.
