This work aims to analyze the possibility of replacing the metal door of a vehicle with a door made of composite materials. Specific issues related to this replacement are analyzed in the paper. Test specimens were made of composite materials of different sizes, using several types of constituents to determine which material might be most suitable to replace metal in the manufacturing of the door. The choice of materials for the car door was made starting from the characteristics of the analyzed composite materials, but also taking into account the manufacturing possibilities and other engineering limitations. The behavior of the automotive structure as analyzed, using the finite element method for determining the stresses in the structure. Experimental verifications were performed on an experimental stand which has been specially designed for this purpose, to validate the proposed model.<\/jats:p>","DOI":"10.3390\/sym13030383","type":"journal-article","created":{"date-parts":[[2021,2,27]],"date-time":"2021-02-27T03:44:31Z","timestamp":1614397471000},"page":"383","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["New Design of Composite Structures Used in Automotive Engineering"],"prefix":"10.3390","volume":"13","author":[{"given":"Vasile","family":"Gheorghe","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Brasov, B-dul Eroilor 29, 500036 Brasov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Luminita","family":"Scutaru","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Brasov, B-dul Eroilor 29, 500036 Brasov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Virgil Barbu","family":"Ungureanu","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Brasov, B-dul Eroilor 29, 500036 Brasov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eliza","family":"Chircan","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Brasov, B-dul Eroilor 29, 500036 Brasov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihai","family":"Ulea","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Brasov, B-dul Eroilor 29, 500036 Brasov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e03716","DOI":"10.1016\/j.heliyon.2020.e03716","article-title":"From aviation to automotive\u2014A study on material selection and its implication on cost and weight efficient structural composite and sandwich designs","volume":"6","author":"Hagnell","year":"2020","journal-title":"Heliyon"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Stylios, G.K.
