In this study, a method combining molecular dynamics (MD) simulation and back propagation (BP) neural network was employed to achieve a balance between self-healing property and mechanical property. In addition, self-healing and mechanical properties were predicted and the influence of different compositions of the system on these properties was investigated by the BP neural network. It was found that the DA bond formed by the furan group of furfuryl glycidyl ether (FGE) and the maleimide group of bismaleimide (BMI) was of great importance for self-healing property, and that diglycidyl ether of bisphenol-A (DGEBA) with a mass fraction of 25%\u201348% could improve the tensile property of the system. Finally, a self-healing epoxy resin system with superior comprehensive properties was designed through the proposed method under four indexes of Young\u2019s modulus (E), self-healing efficiency (<jats:inline-formula>\n                     <jats:tex-math>\n\n<\/jats:tex-math>\n                     <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mi>\u03b7<\/mml:mi>\n                     <\/mml:math>\n                     <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"mrxabf66bieqn1.gif\" xlink:type=\"simple\"\/>\n                  <\/jats:inline-formula>), Ultimate Tensile Strength (UTS), and glass transition temperature (Tg).<\/jats:p>","DOI":"10.1088\/2053-1591\/abf66b","type":"journal-article","created":{"date-parts":[[2021,4,9]],"date-time":"2021-04-09T22:16:23Z","timestamp":1618006583000},"page":"045308","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Properties prediction and design of self-healing epoxy resin combining molecular dynamics simulation and back propagation neural network"],"prefix":"10.1088","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2265-836X","authenticated-orcid":false,"given":"Hao","family":"Luo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Tao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2021,4,21]]},"reference":[{"key":"mrxabf66bbib1","doi-asserted-by":"publisher","first-page":"259","DOI":"10.1016\/j.compositesb.2017.11.056","article-title":"Mechanical properties of glass fibre composites based on nitrile rubber toughened modified epoxy resin","volume":"139","author":"Ricciardi","year":"2018","journal-title":"Composites Part B: Engineering"},{"key":"mrxabf66bbib2","doi-asserted-by":"publisher","first-page":"1194","DOI":"10.1002\/pi.5621","article-title":"Biobased epoxy resin derived from eugenol with excellent integrated performance and high renewable carbon content","volume":"67","author":"Miao","year":"2018","journal-title":"Polym.
