“…Based on the tted models, the low, medium, and high-temperature regimes for the material types can be obtained, as shown in Table 3. A downward trend of IFSS values with increasing temperatures has been reported by researchers [15], [17], [18], [27]- [31] as typical behavior among polymer composites, especially at temperatures above the resin's Tg. Reduced IFSS at high temperatures is potentially caused by molecular chain relaxation of polymer matrices and degradation of the CNT surface.…”

Understanding nanocomposite interfacial bonding under environmental conditions will lead to gamechanging material applications in energy, aerospace, electronics, and infrastructure applications. Carbon nanotube (CNT) yarns with high-temperature toughened matrices are candidates to be used in aircraft and space components. While operating, these components are exposed to severe temperatures, which alter their performance due to changes near the interfacial area. This study investigates the interfacial shear strength of CNT yarns in multiple matrices from near-cryogenic temperatures up to temperatures above the matrix glass transition temperature. Statistical and data-driven approaches are implemented to understand and quantify the interface between inclusion and matrix. The ber bundle pullout test is performed at a broad temperature range for fundamental studies of composite material interfaces and their bonding properties in extreme environments. Analysis showed that IFSS decreases with increasing temperature, especially at temperatures near the resin's glass transition temperature. It was shown that the work required to pull out the CNT from all polymer matrices was reduced by more than 60% between temperature extremes.

“…Additionally, the presence of thermal stresses at the fiber/matrix interface cannot be ignored, which are responsible for fiber matrix interfacial debonding. The combined action of polymer softening and interfacial weakening results in the drastic reduction in the mechanical properties of the CNT‐GE and FCNT‐GE composite at elevated temperature . But, the presence of strong chemical bonds between FCNT and epoxy restricts the debonding process to a greater extent than CNT (represented in Figure ).…”

Effects of carbon nanotube/polymer interfacial bonding on the long‐term creep performance of nanophased glass fiber/epoxy composites

et al. 2019

This article is focused on prediction of the long‐term creep performance of glass fiber/epoxy (GE) composites reinforced with pristine carbon nanotube (CNT) and functionalized carbon nanotube (FCNT). 0.1 wt% of CNT and FCNT are added to GE composites to fabricate CNT‐GE and FCNT‐GE composite laminates, respectively. Flexural tests were carried out at room temperature (RT) and 120°C to assess the effect of environment temperature on the flexural properties of the aforesaid materials. FCNT‐GE showed highest improvement in flexural properties at RT followed by CNT‐GE composite and control GE composite, due to better stress transfer with strong chemical interfacial bonding. By using accelerated deformation at elevated temperature and time‐temperature superposition principle, long‐term creep behavior of GE, CNT‐GE, and FCNT‐GE composites at various reference temperatures (30°C, 60°C, 90°C, and 110°C) has been anticipated. Positive reinforcement efficiency is noted up to ~1010.5 and ~1012.5 years for CNT‐GE and FCNT‐GE, respectively at reference temperature of 30°C, following which it neutralized and moderately became negative. However, at higher temperature this time period is reduced abruptly due to unfavorable thermal stress generation at the CNT/polymer interface. Evaluation of thermomechanical properties were also carried out using dynamic mechanical analysis. Differential scanning calorimetry was used to investigate the variation in glass transition temperature due to CNT/FCNT addition to GE composite. Fractographic study was also carried out to know the mode of failure for CNT‐GE and FCNT‐GE composite flexural tested at room temperature.

“…The nano particles presence effect on the impact resistance improvement in composites has been individually dissected in previous works. [16,19] Primarily, it is necessary to explore the incorporation effect for two nanoparticles of three to investigate the simultaneous effect of nanoparticles in the fabrication of sandwich panels. The contact force-displacement and contact force-time graphs for the reference and the specimens filled with different percentages of nanosilica and CNT under the impact energy of 15 J are displayed in Figure 5.…”

“…However, no considerable research has been conducted on the integration effect of nanocarbon on the impact resistance of sandwich composites. [16][17][18][19][20] Karapappas et al [21] verified that carbon nanotubes (CNT) have a significant strengthening effect because of the large aspect ratio. Therefore, additional energy was required for nano scale crack initiation and propagation, that culminated in impact resistance increase.…”

Considering the massive employment of sandwich panels in multifarious applications, numerous research studies have been conducted on their impact resistance enhancement, one of which, is via simultaneous nanoparticles incorporation including various amounts of silica nanoparticles, clay nanoparticles and carbon nanotubes (CNTs) in to sandwich panels, composed of two glass fiber epoxy composite face sheet and polyvinyl chloride core to render them reinforced. The research objective is to experimentally scrutinize the behavior of nano reinforced sandwich panels under low-velocity impact test conducted at different energy levels. The damaged areas of the panels were investigated via scanning electron microscopy, the result of which demonstrated that the impact resistance of the sandwich panel can be improved by the integration of nanoparticles. The incorporation of 0.3% of CNT, 1% of nano clay, and 3% of nano silica enhanced maximum contact force by 18.6%, compared to the unreinforced equivalent.Increasing the weight fraction of both CNTs and silica nanoparticles, made contribution to sandwich panels impact resistance increase. The presence of nano clay up to 1 wt% improved the maximum contact force; however, the integration of it into matrix more than 1 wt% led to the reduction of maximum contact force, thus weakened the impact resistance of sandwich panel.
