日前,美国生物复合材料公司Sunstrand的研究人员改进了天然纤维的上浆工艺,使其与偶联剂直接作用,从而为提高天然纤维与树脂间的结合力提供了一条新的思路。对于天然纤维,在复合材料制造领域最受关注的是纤维的亲水性及其与树脂间较差的结合性(包括热塑性树脂和热固性树脂)。尽管这两个领域均存在问题, Researchers at Sunstrand, a US biocomposite company, have improved the sizing process of natural fibers to make them act directly on the coupling agent, providing a new idea for improving the bond between natural fibers and resins. For natural fibers, the most interesting area of ​​composite manufacturing is the hydrophilic nature of the fibers and their poor adhesion to resins, including both thermoplastic and thermosetting resins. Although there are problems in both areas,
