摘要：
Hybrid sisal fibers (HSFs) were made by mixing untreated sisal fibers (USFs) with alkali treated sisal fibers (ASFs), and blended with PLA matrix to make PLA/HSFs composite. It was found that the reinforced effect of HSFs was better than that of ASFs. Impact strength and crystallinity of PLA/HSFs had obvious improvements. beta crystal of PLA was found from the XRD graph of PLA/HSFs, which may lead to an enhance in the impact strength and thermal stability.
