Test specimens were obtained by vulcanization using a laboratory hydraulic press. The elastomer crosslinking and the chemical modification of the hemp fiber surface were achieved by a radical reaction mechanism initiated by di(tert-butylperoxyisopropyl)benzene. The influence of the fiber loading on the mechanical properties, gel fraction, swelling ratio and crosslink degree was investigated. The gel fraction, crosslink density and rubber\u2013hemp fiber interaction were evaluated based on equilibrium solvent-swelling measurements using the Flory\u2013Rehner relation and Kraus and Lorenz\u2013Park equations. The morphology of the EPDM\/hemp fiber composites was analyzed by scanning electron microscopy. The water absorption increases as the hemp fiber loading increases.<\/jats:p>","DOI":"10.3390\/ma15196838","type":"journal-article","created":{"date-parts":[[2022,10,9]],"date-time":"2022-10-09T01:43:11Z","timestamp":1665279791000},"page":"6838","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Mechanical Properties and Equilibrium Swelling Characteristics of Some Polymer Composites Based on Ethylene Propylene Diene Terpolymer (EPDM) Reinforced with Hemp Fibers"],"prefix":"10.3390","volume":"15","author":[{"given":"Maria Daniela","family":"Stelescu","sequence":"first","affiliation":[{"name":"National Research and Development Institute for Textile and Leather, Leather and Footwear Institute, 93 Ion Minulescu Street, 031215 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Airinei","sequence":"additional","affiliation":[{"name":"Petru Poni Institute of Macromolecular Chemistry, 41A Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9433-9595","authenticated-orcid":false,"given":"Alexandra","family":"Bargan","sequence":"additional","affiliation":[{"name":"Petru Poni Institute of Macromolecular Chemistry, 41A Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicusor","family":"Fifere","sequence":"additional","affiliation":[{"name":"Petru Poni Institute of Macromolecular Chemistry, 41A Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihai","family":"Georgescu","sequence":"additional","affiliation":[{"name":"National Research and Development Institute for Textile and Leather, Leather and Footwear Institute, 93 Ion Minulescu Street, 031215 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Sonmez","sequence":"additional","affiliation":[{"name":"National Research and Development Institute for Textile and Leather, Leather and Footwear Institute, 93 Ion Minulescu Street, 031215 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihaela","family":"Nituica","sequence":"additional","affiliation":[{"name":"National Research and Development Institute for Textile and Leather, Leather and Footwear Institute, 93 Ion Minulescu Street, 031215 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurentia","family":"Alexandrescu","sequence":"additional","affiliation":[{"name":"National Research and Development Institute for Textile and Leather, Leather and Footwear Institute, 93 Ion Minulescu Street, 031215 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriana","family":"Stefan","sequence":"additional","affiliation":[{"name":"National Institute of Aerospace Research \u201cElie Carafoli\u201d, 220 Iuliu Maniu Blv., 061126 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1007\/s12221-009-0083-z","article-title":"Fabrication of long and discontinuous natural fiber reinforced polypropylene biocomposites and their mechanical properties","volume":"10","author":"Lee","year":"2009","journal-title":"Fibers Polym."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"243947","DOI":"10.1155\/2015\/243947","article-title":"A Review on natural fiber reinforced polymer composite and its applications","volume":"2015","author":"Mohammed","year":"2015","journal-title":"Int.
