The harsh service environment of civil engineering leads to significant degradation of the thermal and mechanical performances of CFRP, which then reduces its service reliability, service safety, and life. Research on the durability of CFRP is urgently needed to understand the long-term performance degradation mechanism. In the present study, the hygrothermal aging behavior of CFRP rods was investigated experimentally through immersion in distilled water for 360 days. The water absorption and diffusion behavior, the evolution rules of short beam shear strength (SBSS), and dynamic thermal mechanical properties were obtained to investigate the hygrothermal resistance of CFRP rods. The research results show that the water absorption behavior conforms to Fick\u2019s model. The ingression of water molecules leads to a significant decrease in SBSS and glass transition temperature (Tg). This is attributed to the plasticization effect of the resin matrix and interfacial debonding. Furthermore, the Arrhenius equation was used to predict the long-term life of SBSS in the actual service environment based on the time\u2013temperature equivalence theory, obtaining a stable strength retention of SBSS of 72.78%, which was meaningful to provide a design guideline for the long-term durability of CFRP rods.<\/jats:p>","DOI":"10.3390\/polym15112490","type":"journal-article","created":{"date-parts":[[2023,5,28]],"date-time":"2023-05-28T15:29:52Z","timestamp":1685287792000},"page":"2490","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["The Aging Behavior and Life Prediction of CFRP Rods under a Hygrothermal Environment"],"prefix":"10.3390","volume":"15","author":[{"given":"Xiaodong","family":"Liu","sequence":"first","affiliation":[{"name":"School of Energy and Built Environment, Guilin University of Aerospace Technology, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingyong","family":"Su","sequence":"additional","affiliation":[{"name":"School of Energy and Built Environment, Guilin University of Aerospace Technology, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Civil Engineering and Architecture, Harbin University of Science and Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaopeng","family":"Song","sequence":"additional","affiliation":[{"name":"School of Energy and Built Environment, Guilin University of Aerospace Technology, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"432","DOI":"10.1016\/j.compscitech.2008.11.012","article-title":"Influence of hygrothermal environment on thermal and mechanical properties of carbon fiber\/fiberglass hybrid composites","volume":"69","author":"Tsai","year":"2009","journal-title":"Compos.
