Hygrothermal ageing of epoxy based coatings
Journal of Materials Science, 1982Water sorption kinetics, and equilibria at different temperatures, and mechanical tests have been performed on different epoxy based coatings. The resins show different water transport properties and consequently different mechanical properties of the wet system, depending on the temperature and formulation.

Hygrothermal aging effects on mechanical and fatigue behaviors of a short- natural-fiber-reinforced composite [PDF]
International Journal of Fatigue, 2018 A new natural fiber composite made of high density polyethylene (HDPE) and 40% wt of short birch fibers (SBF) was developed to replace polyamide (better known under its industrial name “Nylon”) in spur gear manufacturing. The effect of hygrothermal aging

Effect of Hygrothermal Aging on Polyetherimide Composites
Journal of Reinforced Plastics and Composites, 2007The aim of this study is to investigate the effect of hygrothermal aging on both the static and thermo-mechanical behavior of polyetherimide composites. Tensile testing and dynamic mechanical thermal analysis were performed on the hygrothermally aged polyetherimide composites in the climatic cabin. The decrease in the T

Durability of GFRP nanocomposites subjected to hygrothermal ageing
Composites Part B: Engineering, 2015Abstract This paper presents long term durability prediction of 0–5 wt.% nanoclay/vinylester/glass fibre nanocomposites based on their tensile strength retention in accelerated hygrothermal ageing using Arrhenius rate model. The specimens were exposed to 30 °C, 50 °C and 60 °C and 95% relative humidity for 75 days and tested for tensile strength ...

The hygrothermal aging process and mechanism of the novolac epoxy resin
Composites Part B: Engineering, 2016Abstract Novolac epoxy resins, with the high glass transition temperature (Tg) and excellent mechanical strength, are widely applied in the molding and sealing compounds for the production of electronic devices. However, weather exposure and environmental elements are inclined to affect their durability severely. This work focuses on the hygrothermal

Hygrothermal Aging of Silane-Laced Epoxy Coatings
Journal of Adhesion Science and Technology, 2010Abstract The impact of silane on the hygrothermal stability of epoxy coatings was investigated by specular neu-tron reflectivity (NR). By comparing the hygrothermal degradation behavior of neat novolac epoxy coatingand corresponding bis[3-(triethoxysilyl)propyl]tetrasulfide-laced epoxy coating, the role of silane was elu-cidated.

The Hygrothermal Aging Life Models of Solid Propellant
Advanced Materials Research, 2012The temperature and humidity are two main environmental factors, which have influence on the life of solid propellant. Comparing with single factor aging life model, hygrothermal aging life model is more feasible, which takes temperature and humidity into consideration. In this paper two hygrothermal aging life models were established.

Aging characteristics of epoxy resin in hygrothermal environment
2017 International Symposium on Electrical Insulating Materials (ISEIM), 2017Because of excellent electrical properties, epoxy resin is widely used in packaging and casting power equipment. Moisture and temperature in the environment are inclined to seriously affect the insulation tolerance of epoxy resin. This work focuses on the aging characteristics of epoxy resin in hygrothermal environment. The effect of hygrothermal aging

Accelerated Hygrothermal and UV Aging of Thermoplastic Polyurethanes
High Performance Polymers, 2008Thermoplastic polyurethanes (PU) were prepared from 4,4'-diphenyl methane diisocyanate (MDI), polyether polyol and 1,4 butane diol with and without a hindered amine light stabilizer (Tinuvin®-123) and UV absorber (Tinuvin®-400). The accelerated hygrothermal and UV aging were performed at different humidity and aging temperatures for 720, 1440, and 2160
