The WCPF in the waste corrugated paper is extracted by beating in a Valli beating machine for different time lengths and grinding in a disc grinder. The effects of beating time and the content of WCPF on the microstructure, mechanical properties, thermal decomposition process, and crystallization properties of the WCPF\/PLA composite were studied. The result shows that the WCPF can be well separated from each other and can be evenly dispersed in the PLA matrix. When 25 wt% WCPF which was beat for 30 min was used, the composite has the greatest improvement in tensile property. This study provides a new process for the recycling of waste paper in the application of polymer reinforcement. The research on waste paper fiber and degradable polymer composite is of great significance for reducing environmental pollutants and developing circular economy.<\/jats:p>","DOI":"10.3390\/polym14173562","type":"journal-article","created":{"date-parts":[[2022,8,30]],"date-time":"2022-08-30T01:37:55Z","timestamp":1661823475000},"page":"3562","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["The Reinforcing Effect of Waste Corrugated Paper Fiber on Polylactic Acid"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7829-5468","authenticated-orcid":false,"given":"Jian","family":"Su","sequence":"first","affiliation":[{"name":"Faculty of Printing, Packaging Engineering and Digital Media Technology, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiwei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Faculty of Printing, Packaging Engineering and Digital Media Technology, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changqing","family":"Fang","sequence":"additional","affiliation":[{"name":"Faculty of Printing, Packaging Engineering and Digital Media Technology, Xi\u2019an University of Technology, Xi\u2019an 710054, China"},{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an 710048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yamin","family":"Zheng","sequence":"additional","affiliation":[{"name":"Faculty of Printing, Packaging Engineering and Digital Media Technology, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mannan","family":"Yang","sequence":"additional","affiliation":[{"name":"Faculty of Printing, Packaging Engineering and Digital Media Technology, Xi\u2019an University of Technology, Xi\u2019an 710054, China"},{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an 710048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Pei","sequence":"additional","affiliation":[{"name":"Faculty of Printing, Packaging Engineering and Digital Media Technology, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhigang","family":"Huang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Processing and Quality Evaluation Technology of Green Plastics of China National Light Industry Council, Beijing Technology and Business University, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105854","DOI":"10.1016\/j.resconrec.2021.105854","article-title":"Upcycling strategies for old corrugated containerboard to attain high-performance tissue paper: A viable answer to the packaging waste generation dilemma","volume":"175","author":"Zambrano","year":"2021","journal-title":"Resour.
