Study of tensile behavior for high-performance fiber materials under high-temperature loads

Abstract

Textile high-performance filament yarn subjected to extremely high thermal loads can be found in various technical application fields. Besides the mechanical loads, textile fiber materials have to also satisfy high safety requirements in these applications with respect to thermal loads. Some of the main fields of application in the field of mechanical engineering are turbines, drive devices, rocket components and fire protection coatings. Textile grid-like structures are also being increasingly used in civil engineering as reinforcements (textile concretes). The design and development of textile structures for these applications demands studying and acquiring the material behavior under high thermal loads. Neither sufficient data nor standardized testing methods have been extensively achieved for evaluating the tensile characteristics of filament yarns under thermal influences. Hence, studying the thermal behavior of these yarns, which are used as input material for the reinforcing structures, is essential. The impact of the standard atmospheric condition on the oxidation behavior of the yarns, as in the case of carbon filament yarns and their influence on the physicochemical and tensile mechanical properties, have to be studied as well. This paper aims to address this issue and provides an insight into the current research about the development and realization of a novel test stand and the subsequent study of tensile mechanical behavior for textile high-performance fiber material under extreme thermal loads together with their physicochemical behavior.

Effect of heat treatment on the morphology, diameter and mesoporous of superfine glass fiber

“…); the influence of diffusion temperature on the water uptake and subsequent degradation behavior of multi-walled carbon nanotube embedded in glass fiber/epoxy composites was elucidated under the temperatures of 25 C and 90 C, respectively (Prusty et al, 2018). For glass fiber itself, the strength degradation of the bundles of E-glass fiber and Advantex glass fibers were investigated under high temperatures up to 650 C (Feih et al, 2009); the tensile mechanical behavior of AR-glass filament yarn was researched under the temperatures of 100-700 C (Younes et al, 2014); the thermal stability, thermo-mechanical and mechanical properties of glass fiber rovings were improved at the temperature of 20-400 C by polysilazane based thermal resistant coating treatment (Shayed et al, 2010.). Those researches focused on the mechanical properties of glass fiber at high temperature, as well as the method of improving its thermal mechanical properties, however ignored the performance of glass fiber itself at high temperature.…”

Establishment of a digital simulated testing platform for radiation protection performance and preparation of three-layer coated flexible composites

“…Node coordinates of each warp and weft yarn were recorded, again according to the recorded coordinates and measured parameters of yarn, in order to accurately reflect the winding path, cross-section shape and interwoven state of the yarn. [21][22][23] The single drawn weft yarn model was as shown in Figure 6(a); the rest of the yarns using the same method were drawn into the structure as shown in Figure 6(b).…”

Carbonization of polyacrylonitrile-based fibers under defined tensile load: Influence on shrinkage behavior, microstructure, and mechanical properties

“…Thus, the effect of tensile load during carbonization on fiber properties is of high interest and has already been the topic of several publications. While some publications refer to the continuous fiber production process close to industrial manufacturing [29][30][31], others use a batch process [32][33][34][35][36][37].…”

“…Here the free choice of temperature, atmosphere, and stress program, which allows for the measurement of the temperature-dependent evolution of material parameters, outweighs the fact that this process is further away from the industrial process. Depending on the parameters addressed, those batch processes are using conventional furnaces [32,34] or alternative concepts like infrared radiation to heat the fiber bundles [37]. To accurately measure the induced length change of the fibers during carbonization, a homogenous heat profile over the clamped fiber length must be guaranteed.…”
