Special Issue Information

Dear Colleagues,

Polymers and their composites are increasingly being applied in extreme environments, such as cryogenic, high-temperature, corrosive, oxidizing or biological environments, to substitute for traditional metal materials in load-bearing applications due to their properties of low density, flexibility, chemical stability, biodegradability and so on. In recent years, tremendous progress has been made in many engineering fields, driven mostly by new applications of polymers and their composites. In the future, they will be in more demand for equipment used in extreme environments; see, for example, the large demand for promoting the cryogenic mechanical, leakage resisting, anti-thermal, thermal insulating or electromagnetic-radiation-resisting properties of polymer matrix composites for the development of heavy lift rockets and deep space exploration. Fundamentally understanding the behaviour of polymer chains govern, to a large extent, the relationships between the structure, properties, processing, and performance of the corresponding materials, which forms the basis for a more efficient, rational, and economical design of new products and processes for specific applications in several new technologies where polymers are used.

Recognizing the importance of both theories and experiments in understanding the properties of materials across scales and under a variety of conditions, this Special Issue of Polymers invites contributions addressing several aspects of polymer matrix composites, such as design and preparation of polymers, design and processing of composites, testing methodologies and standards, reliability evaluation and life assessment, etc. The above list is only indicative and by no means exhaustive; any original theoretical or engineering experimental work or review article on the polymer matrix composites used in extreme environments is welcome. We hope that these contributions will address a variety of application fields relative to extreme environments, including aerospace engineering, chemical engineering, marine engineering, mechanical engineering, cryogenic engineering, biological or medical engineering, etc.

Abstract
This paper presents the results of an evaluation of corrosion properties of PEO pretreated AlMg3 aluminum alloy samples with polymer coatings obtained by dip-coating in a suspension of superdispersed polytetrafluoroethylene (SPTFE) in a solution of polyvinylidene fluoride (PVDF) in N-methyl-2-pyrrolidone at different PVDF:SPTFE [...] Read more.
This paper presents the results of an evaluation of corrosion properties of PEO pretreated AlMg3 aluminum alloy samples with polymer coatings obtained by dip-coating in a suspension of superdispersed polytetrafluoroethylene (SPTFE) in a solution of polyvinylidene fluoride (PVDF) in N-methyl-2-pyrrolidone at different PVDF:SPTFE ratios (1:1, 1:3, 1:5, and 1:10). The electrochemical tests showed that samples with a coating formed at a ratio of PVDF to SPTFE of 1:5 possessed the best corrosion properties. The corrosion current density of these samples was more than five orders of magnitude lower than this parameter for bare aluminum alloy. During the 40-day salt spray test (SST) for samples prepared in a suspension at a PVDF:SPTFE ratio of 1:1–1:5, the formation of any pittings or defects was not detected. The PVDF:SPTFE 1:5 sample demonstrated, as a result of the 40-day SST, an increase in corrosion current density of less than an order of magnitude. The evolution of the protective properties of the studied samples was assessed by a two-year field atmospheric corrosion test on the coast of the Sea of Japan. It was revealed that the samples with the PVDF:SPTFE 1:5 coating had electrochemical parameters that remained consistently high throughout the one year of exposure. After this period, the polymer layer was destroyed, which led to a deterioration in the protective characteristics of the coatings. Full article

The effects of thermal aging at 85~145 °C in air on the tensile and flexural mechanical properties of 20% glass fiber (GF)-reinforced commercial grade polybutylene terephthalate (PBT) composites were studied. The results showed that as the aging temperature increased, the tensile and flexural strength of the GF/PBT composites significantly decreased. However, the elastic modulus of the composites was almost independent of aging. As the aging temperature increased, the separation between GF and the PBT matrix became more pronounced, and the fibers exposed on the surface of the matrix became clearer and smoother, indicating a decrease in interfacial adhesion between the PBT matrix and GF. The reason for this decrease in strength and brittle fracture of composites is the interface damage between the GF and PBT matrix caused by the difference in their thermal expansion coefficients during thermal aging.

Recently, the application of cryogenic hoses in the field of cryogenic media has become a hot topic, especially in the industry of offshore liquefied natural gas and aerospace field. However, the structure of cryogenic hoses is complex, and reasonable structural properties are required due to the harsh working conditions. There is still plenty of scope for further development to improve the performance in all aspects. In this paper, the current development status of cryogenic hoses for liquefied natural gas (LNG) transportation is reviewed first, including the types, manufacturers, structural forms, performance, and key technical challenges. And then, the recent progress and prospect of cryogenic hoses for cryogenic liquid transportation (such as LNG and liquid oxygen) are summarized, including structure design, low-temperature resistant polymers, liquid oxygen compatible polymers, and leakage monitoring technologies. This paper provides a comprehensive overview of the research development and application of cryogenic hoses. Moreover, future research directions have been proposed to facilitate its practical applications in aerospace. Full article
