结晶纳米纤维纤维素具有显著的力学性能：杨氏模量约为130 GPa，抗拉强度在750-1000 MPa之间。最近，人们对在工程复合材料和泡沫材料中开发这些特殊性能越来越感兴趣。在这里，我们比较了纳米纤维纤维素复合材料和泡沫的力学性能的测量与基于复合材料和泡沫模型的潜在性能。我们发现目前的NFC泡沫尚未达到其潜力，并建议修改其微观结构以改善机械性能。
Crystalline nanofibrillar cellulose has remarkable mechanical properties: a Young's modulus of about 130 GPa and a tensile strength in the range of 750-1000 MPa. Recently, there has been increasing interest in exploiting these exceptional properties in engineering composites and foams. Here, we compare measurements of the mechanical properties of nanofibrillar cellulose composites and foams with their potential properties based on models for composites and foams. We find that current NFC foams do not yet reach their potential and suggest modifications to their microstructure for improved mechanical performance.
