“…The complex loading in compression of the Taylor test, where stress, strain rate, and final strain vary within the specimen makes it an ideal test for validating constitutive models, where the complex loading is thought to provide a more robust test of the model [36]. In polymers, the test has been used to understand the behavior of the materials under complex loading for modeling efforts [108][109][110][111][112][113] and to elucidate phase transitions in the polymeric materials [12,114].…”

The mechanical properties of polymers are becoming increasingly important as they are used in structural applications, both on their own and as matrix materials for composites. It has long been known that these mechanical properties are dependent on strain rate, temperature, and pressure. In this paper, the methods for dynamic loading of polymers will be briefly reviewed. The high strain rate mechanical properties of several classes of polymers, i.e. glassy and rubbery amorphous polymers and semi-crystalline polymers will be reviewed. Additionally, time-temperature superposition for rate dependent large strain properties and pressure dependence in polymers will be discussed. Constitutive modeling and shock properties of polymers will not be discussed in this review.

“…The cracks from the central region fail the cylinder before those from the expanding footprint become significant. PEEK exhibits ductile deformation, darkening (consistent with a reduction in crystallinity) and damage behind the impact surface [8,13]. The combination of the Taylor geometry with X-ray tomography has shown that one may obtain a higher fidelity view of damage in 3D than seen before.…”

“…Poly(etheretherketone) (PEEK), as a high performance semi-crystalline engineering polymers with excellent properties such as high thermal stability, mechanical properties, chemical resistance and electrical properties, has attracted intense research attention since developed by ICI at 1978. It provides a new platform for application in aerospace, automobiles, electronics and medical devices [3][4][5].However, PEEK is an expensive polymer due to the high melting point (~334 °C) and viscosity, more than four times the price of other engineering polymers, which restricts its further application.…”

The effects of crystal and amorphous polymers on the structure, morphology, crystalline and thermal properties of PEEK have been investigated by using FT-IR, SEM, DSC and TGA. The interaction existing in PEEK/PPS and PEEK/PEI alloys were stronger than that in PEEK/PPS/ PEI alloys. The SEM results revealed that homogeneous structure exists in the alloys of PEEK/ PPS, PEEK/PEI and PEEK/PPS/PEI. All of the binary and ternary alloys based PEEK exhibits single glass transition temperature (Tg) in full composition range. When PEI was added to the PEEK/PPS alloys, the Tg of PEEK/PPS/PEI alloys increased from 146 °C to 179 °C. The crystallinity degree of PEEK increased when PPS or PEI was added in heating process, while increased firstly and then decreased with increasing the content of PPS or PEI in cooling process. The crystallization peak of PEEK/PPS/PEI alloy disappears in the ratio of 50/25/25. The thermal decomposition temperature (Td 5%) of PEEK/PPS and PEEK/PEI alloys decreased when PPS and PEI were added, the Td of PEEK/PPS/PEI alloy in the ratio of 70/15/15 presented at 510 °C, which was lower than pure PEEK and pure PEI, higher than PPS.Keywords: PEEK, PPS, PEI, plastic alloys, crystallization, thermal properties.Влияние кристаллических и аморфных полимеров на структуру, морфологию, кристаллические и термические свойства ПЭЭК были исследованы с помощью фурье-ИК спектроскопии, сканирующей электронной микроскопии, ДСК и ТГА. Взаимодействие компонентов в сплавах ПЭЭК/ПФС и ПЭЭК/ПЭИ проявлялось сильнее, чем в ПЭЭК/ ППС/ПЭИ. Сканирующая электронная микроскопия показала гомогенную структуру сплавов ПЭЭК/ПФС, ПЭЭК/ПЭИ и ПЭЭК/ПФС/ПЭИ. Все двойные и тройные сплавы на основе ПЭЭК проявляют только одну температуру перехода (Tg) во всем интервале составов. При добавлении ПЭИ к ПЭЭК/ПФС, Tg сплавов ПЭЭК/ПФС/ПЭИ возрастала с 146 до 179°С. Степень кристалличности ПЭЭК возрастала при добавлении ПФС и ПЭИ в процессе нагревания и снижалась при добавлении ПФС и ПЭИ в процессе охлаждения. Пик кристаллизации сплава ПЭЭК/ПФС/ПЭИ исчезает в области 50/25/25. Температура термического разложения (Td) сплавов ПЭЭК/ПФС и ПЭЭК/ПЭИ уменьшалась при добавлении ПФС и ПЭИ. Td сплава ПЭЭК/ПФС/ПЭИ в соотношении 70/15/15 была 510°С, что ниже, чем у чистых ПЭЭК и ПЭИ, но выше, чем у ПФС. 56Functional materials, 23, 1, 2016 Chen Jian-bing et al. / Crystalline and thermal properties ...
