“…In [4,5], the moisture absorption behaviour and associated mechanical degradation of unidirectional hybrid (carbon/glass) composite rods for overhead conductors was evaluated. The researches in [6,7] studied the moisture diffusion process in GFRP composites for a bridge deck and in pultruded profiles for structural applications, respectively. The effects of seawater and warm environment was investigated e.g.…”

“…For glass fiber reinforced polymer flame retardant system, the flame retardant fillers and interface between fiber and matrix can decline easily in such severe environment. Though there have been some researches about the effect of single environment elements above on the properties of fiber reinforced polymer composites , it is still lack of more information about the influence of a combination of different environment agents (as natural exposing) on glass fiber reinforced PP flame retardant composites, especially on the flame retardancy and thermal degradation kinetics.…”

In this work, the composites based on long glass fiber reinforced polypropylene/intumescent flame retardant (LGFPP/IFR) were prepared by melt blending. This article presented an experimental research on the influence of combined environment elements in natural condition on the properties of LGFPP/IFR composites with 0–12 months ageing. The flammability and thermal properties of the composites were investigated by limiting oxygen index (LOI), UL–94 test, cone calorimeter test (CCT), thermal gravimetric analysis (TGA), mechanical properties test and energy dispersive X‐ray analysis (EDAX). The LOI values increased from 27.5 to 28.3 in 0–6 months ageing, and then decreased back, however, the TGA curves shift to the lower temperature. The thermal degradation kinetics were analyzed and the apparent active energy (E) of aged and unaged samples were calculated by Flynn‐Wall‐Ozawa method. The results indicated that much lower E values were obtained after 3–12 months ageing. EDAX data proved that the IFR particles gathered on the surface of samples in natural exposing, by which had some effect on the thermal stability and flame retardancy of the composites. The mechanical properties showed a global decrease in the whole ageing period by matrix degradation and interface debonding under the influence of combined environment elements. POLYM. ENG.

“…C ∞ has been reported to be independent of temperature, whereas either positive or negative temperature dependences have also been observed . As for the fiber content in composites, it is considered to have an important influence on both D and C ∞ . Humidity as another critical environmental factor has also been taken into account.…”

“…Humidity as another critical environmental factor has also been taken into account. It is usually considered to have a positive influence on diffusion . On the basis of a literature survey, it is known that environmental factors (including temperature, humidity, and fiber content) affect the parameters of the Fickian model.…”

Moisture diffusion in polyamide 6,6 (PA66) and its short glass fiber-reinforced composites has a great influence on their mechanical properties and service lives under hydrothermal environments. Hence, the moisture diffusion in neat PA66 and its composites was studied comprehensively in this study with the general Fickian model. To systematically investigate the effects of the fiber content, humidity, temperature, and humidity-temperature coupling effect on the diffusion coefficient and equilibrium concentration, gravimetric experiments for the PA66 composites were carried out under different hydrothermal conditions. The results show that the equilibrium moisture concentration depended on the relative humidity and fiber content but only depended weakly on temperature. The diffusion velocity was affected by the three aforementioned factors with different trends. The analysis of variance demonstrated that the humidity-temperature coupling effect played an important role in the diffusion process. The regression analysis gave the corresponding quadratic regression equations.
