Hygrothermal Aging of Silane-Laced Epoxy Coatings

Journal of Adhesion Science and Technology, 2010
Abstract 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, 2012
The 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.

Hygrothermal aging of flip-chip assembled MOEMS

Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2017
Low cost and miniaturized solutions for assembly of optical microelectromechanical systems (MOEMS) are critical for increased exploitation of optical sensors and devices in consumer applications. Examples of applications based on optical sensors and devices already near or on the market are auto-focus lenses and pico-projectors for mobile phones ...

Hygrothermal aging of mastic samples

This study examines the aging behavior of mastic samples subjected to hygrothermal condi-tions in a pressure aging vessel (PAV) for 10, 20, and 40 hours, as well as to reactive oxygen species and hu-midity in Vienna Binder Aging (VBA-WET). Fourier-transform infrared spectroscopy (FTIR) was used to analyze the chemical aging processes, and principal ...

Aging characteristics of epoxy resin in hygrothermal environment

2017 International Symposium on Electrical Insulating Materials (ISEIM), 2017
Because 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

Hygrothermal Aging Effect on Fatigue Behavior of GLARE

Journal of Reinforced Plastics and Composites, 2008
This article reports on the experimental characterization of the fatigue behavior of GLARE laminate taking into account the hygrothermal effects. The environmental factors can limit the applications of composites by deteriorating the mechanical properties during service.

Durability of hygrothermally aged graphite/epoxy woven composite under combined hygrothermal conditions

International Journal of Fatigue, 2002
Abstract The objective of this study was to examine the effects of hygrothermal aging on the durability of a graphite/epoxy woven composite material system. The study was part of a larger project in which the objective was to evaluate and model the effects of moisture, temperature, and combined hygrothermal conditions on the strength and life of a ...

Accelerated Hygrothermal and UV Aging of Thermoplastic Polyurethanes

High Performance Polymers, 2008
Thermoplastic 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

Hygrothermal Aging Effects on Buried Molecular Structures at Epoxy Interfaces

Langmuir, 2013
Interfacial properties such as adhesion are determined by interfacial molecular structures. Adhesive interfaces in microelectronic packages that include organic polymers such as epoxy are susceptible to delamination during accelerated stress testing.

Stress relaxation of a polycarbonate blend after hygrothermal aging

Mechanics of Time-Dependent Materials, 2012
This work has studied the competing effects of physical aging and moisture absorption on the relaxation behaviour of a polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) polymer blend after being subjected to both thermal and hygrothermal aging. Physical aging was simulated by thermal aging the blend at temperatures up to 80 ∘C which is below the ...
