Ramie, sisal and curau\u00e1 fibers were selected as natural fiber reinforcements for the epoxy matrix based composites, which were produced by the hand lay-up technique. Tensile, flexural and impact tests were carried out according to American society for testing and materials (ASTM) standards to characterize the hybrid composites, while differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to evaluate the thermal properties. It was found that the mechanical properties are improved by hybridization of sisal based composites. The thermal analysis showed that the hybridization did not significantly affect the thermal stability of the composites. A scanning electron microscopy (SEM) was used to examine the fracture surface of the tested specimens. The SEM images showed a brittle fracture of the matrix and fiber breakage near the matrix.<\/jats:p>","DOI":"10.3390\/polym12040866","type":"journal-article","created":{"date-parts":[[2020,4,9]],"date-time":"2020-04-09T14:42:03Z","timestamp":1586443323000},"page":"866","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":98,"title":["Mechanical and Thermal Characterization of Natural Intralaminar Hybrid Composites Based on Sisal"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0610-4826","authenticated-orcid":false,"given":"Alexandre L.","family":"Pereira","sequence":"first","affiliation":[{"name":"Federal Center of Technological Education in Rio de Janeiro, CEFET\/RJ, Rio de Janeiro 20271-110, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8378-2292","authenticated-orcid":false,"given":"Mariana D.","family":"Banea","sequence":"additional","affiliation":[{"name":"Federal Center of Technological Education in Rio de Janeiro, CEFET\/RJ, Rio de Janeiro 20271-110, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8430-8904","authenticated-orcid":false,"given":"Jorge S.S.","family":"Neto","sequence":"additional","affiliation":[{"name":"Federal Center of Technological Education in Rio de Janeiro, CEFET\/RJ, Rio de Janeiro 20271-110, Brazil"}]},{"given":"Daniel K.K.","family":"Cavalcanti","sequence":"additional","affiliation":[{"name":"Federal Center of Technological Education in Rio de Janeiro, CEFET\/RJ, Rio de Janeiro 20271-110, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1552","DOI":"10.1016\/j.progpolymsci.2012.04.003","article-title":"Biocomposites reinforced with natural fibers: 2000\u20132010","volume":"37","author":"Faruk","year":"2012","journal-title":"Prog.
