“…Chuang [30] studied the mechanical properties of the compressed mould of PA6:TPU (80:20) and found the presence of small holes that cause a decrement in tensile stress. Other study conducted by Zo et al [35] also reported the development of small holes in the PA6 and TPU blend composites. Both studies prepared the PA6:TPU blends at the temperature range of 230 to 260°C.…”

“…The melting point of hybrid fibres were lower than that of PA6 with a small endothermic peak of TPU. The decrease in the melting temperature of hybrid fibres can be linked to the interactions between amide group and urethane/urea group via hydrogen bonding [35]. PA6 and TPU could form extensive hydrogen bonding due to their chemical structures and availability of relevant functional groups [34,41].…”

“…The blending of PA6 and TPU via melt spinning can be of further interest as the functional groups present in both polymers; hydroxyl and carbonyl groups will form hydrogen bonding with amide and urethane/urea group [34,35].…”

“…Полімерні нанокомпозити на основі еластомерів з високою електропровідністю застосовуються в багатьох областях виробництва: електропровідних покриттів до електромагнітного екранування мобільної електроніки [1][2]. Найчастіше, для створення таких еластомерних нанокомпозитів використовують матрицю на основі поліуретану (ПУ) та різноманітні наповнювачі, наприклад технічний вуглець [3], металеві частинки [4] або вуглецеві волокна [5], при цьому пороги перколяції для таких систем становлять 5-10 %.…”

Використовуючи метод імпедансної спектроскопії проведено дослідження особливостей електропровідності систем на основі сітчастих поліуретанів та вуглецевих нанотрубок в залежності від величини зовнішнього тиску. Встановлено, що залежність електропровідності від тиску проявляє перколяційну поведінку. Виявлено механізми нелінійної зміни електропровідності зі зростанням тиску. Показано, що досліджувані системи є перспективними п'єзорезистивними матеріалами для створення сенсорів тиску.

The effect of thermo‐oxidative aging on the vibration damping characteristics of the conventional fabric composites reinforced by three‐dimensional (3D) and four‐directional (4Dir) braided preform and laminated plain woven fabric and the 3D‐4Dir braided graphene‐based carbon fiber composites was investigated. Specimens were isothermally aged at 140 °C for various periods of time up to 1,200 h. The results indicated that the thermo‐oxidative aging resulted in deterioration of the matrix and interface performance, in the form of chain scissions, weight loss, microcracks and interfacial debonding, which should be responsible for the decrease of nature frequency and the increase of damping coefficient of the composites. After aging for 1,200 h, the first nature frequency and first damping coefficient retention rates of 3D‐4Dir braided graphene‐coated carbon fiber/epoxy composite were 5.5% and 6.4% higher than those of laminated composite, respectively. One of the reasons was the integrated structure of 3D‐4Dir braided composite exposed lower fiber end area to air than that of laminated composite, leading to less interface oxidation. Another reason was that the graphene reinforced gradient interphase provided an effective shield against interface oxidation and restricted the movement of the different phase of the materials at the composites interface. This synergetic reinforcing effect of 3D‐4Dir braided structure and graphene reinforced hierarchical interface provides an easy and effective way to design and improve the thermo‐oxidative stability of carbon fiber reinforced polymer composites.
