“…This technique is also suitable to deliver carbon nanofillers on prepreg materials by a relatively simple process. In this regard, our research group reported that the use of carbon nanostructures (CNTs and graphene‐related materials) by spray coating technique improves the interlaminar fracture properties of prepreg‐based carbon fiber/epoxy composites . Other studies have demonstrated that the addition of multiwalled carbon nanotubes (MWCNTs) on glass fiber fabrics by spray coating can increase the electrical self‐sensing capabilities of composite laminates …”

The influence of seawater (SW) and distilled water (DW) aging on low‐velocity impact behavior of glass fiber/polymer laminates with and without multiwalled carbon nanotubes (MWCNTs) is experimentally investigated. To this aim, unidirectional glass fiber fabrics were coated with 0.75 wt% MWCNTs by airbrushing, infused with resin (epoxy or vinylester), and cured. Then, composite laminates with and without MWCNTs were cut into specimens for low‐velocity impact testing and exposed to hydrothermal aging by immersing them to SW and DW at 60°C for ~2000 h. After that time of conditioning, dry and wet specimens were tested using a drop‐weight tower with an impact energy of 15 J. Results showed that the moisture absorption content of composite laminates exposed to SW and DW aging is considerably higher on epoxy‐based specimens with respect to vinylester ones. The impact tests revealed that the measured impact peak force and absorbed energy in wet specimens are significantly lower compared to dry specimens due to plasticizing effect of the matrix. With the incorporation of MWCNTs into the laminates, the absorbed energy is increased due to additional damage mechanisms induced at CNT‐rich regions during the impact loading. It was also found that the damage area of the laminates after impact tends to be more prominent for laminates fabricated using vinylester resin than for those using epoxy resin as a result of its brittle behavior during impact loading. Post impact damage analyses by ultrasonic C‐scan imaging and scanning electron microscopy showed that matrix cracking, fiber breakage, fiber/matrix debonding, and delamination are the main damage mechanisms induced in the dry and wet specimens during impact.

“…Consequently aluminum must be reinforced with a ceramic material that have high strength, high wear resistance and low CTE. It is well known that reduced graphene oxide (rGO) and carbon nanotube (CNT) reinforcements are ceramic materials with superior mechanical properties and thermal stability [7].…”

Aluminum matrix composites reinforced with reduced graphene oxide (rGO) and hybrid of carbon nanotube (CNT) and rGO are fabricated by solution coating powder metallurgy process. The hardness, wear resistance and coefficient of thermal expansion (CTE) of the reinforced aluminum composites and the associated microstructural changes with rGO range (0.2-0.6 wt. %) and hybrids of 0.2 wt. % CNT-rGO at different ratios have been investigated. The intensive microstructural observations show that rGO is adsorbed on Al particles and uniformly distributed in the Al matrix composites. The hardness values of the composites increase significantly with rGO reinforcement exhibiting the maximum hardness at 0.4 wt. % rGO. Compared with the hybrid composites CNT-rGO/Al counterparts fabricated by the same route and wt. percent of 0.2, the hardness values in the hybrid CNT-rGO increase considerably. Similar to the hardness, the results of wear tests also exhibit corresponding variation in the values of the wear rates. The improvement in the wear resistance of the hybrid CNT-rGO/Al composite is pronounced in this work. Whereas the rGO reinforcements decrease significantly the wear rate of the aluminum-base by 98%, the wear resistance of the corresponding hybrid CNT-rGO is significantly higher than that of the preceding composites. Maximum CTE reduction of 28% was recorded for hybrid CNT-rGO (1:1) reinforced composite.

“…Mixed‐matrix materials (MMMs) are composites, often formed into thin films, consisting of a continuous phase (matrix) and a dispersed particle phase (filler). Over the past three decades, these materials have been investigated for various applications including membranes for separations, reinforced materials for structures, and wound dressings, among others. By creating MMMs, properties of both the matrix and filler are exploited, and oftentimes enhanced, resulting in superior properties than either the matrix or filler alone.…”

The use of mixed-matrix materials (MMM) has become a major topic of research in recent years, due to unique properties achieved in these composites. In this work, biochar from sunflower seed hull pyrolysis and biochar/polysulfone (PSF) MMMs were produced and characterized. The optimal pyrolysis temperature for biochar production was determined to be 500 C. The resulting biochar properties were an iodine number of 203 mg/g and a pore volume of 0.595 mL/g. In MMM fabrication, the use 4% ethanol as nonsolvent in the wet phase inversion process increased the glass transition temperature by 8 C, indicating improved biochar/PSF interaction. The presence of biochar was shown to create pores in otherwise dense surfaces. The critical surface energy was also increased by the addition of biochar from 28.6 mN/m in pristine PSF to 35.7 mN/m in biochar/PSF MMMs. We identified and discussed several potential applications based on the determined properties.
