“…The degradation mechanism of epoxy resins (Figure 10(c)) showed three distinct mechanisms—the first which is most prominent at around 400°C, which corresponds to the beginning of polymer decomposition and loss of volatiles; 19 the second mechanism around 550°C, which is related to decomposition and burn-up of the resin. 19,22 The beginning of the peak corresponding to the domination of the third mechanism is visible to high temperatures—over 640°C. This mechanism is associated with the degradation of carbon fibers.…”

“…17 –19 Several researchers developed methods based on TGA to estimate constituents content in the epoxy composites. 18,20 –24 Some of them are not straightforward and require two-step analysis with separate measurement of reference fiber only 20 or matrix only 24 sample. Limited number of reports showed attempts at the application of thermogravimetry to characterize TP materials with moderate thermal resistance.…”

The high chemical resistance of the advanced thermoplastic polymers, such as polyether ether ketone (PEEK), polystyrene (PS), or polyamide (PA), makes methods of the composites’ composition evaluation based on chemical etching difficult and tedious. Wider application of the composites with thermoplastic matrix creates a need to find more capable, faster, and easier method of fiber and void content determination. Thermogravimetric analysis (TGA) is known to be one of the most promising candidates. Numerous reports have shown that TGA could be successfully applied for glass-reinforced composites. In this study, carbon fiber/PEEK composite was investigated. Initial tests showed that a simple method based on total burn-up of the matrix cannot be used for such advanced composites due to the high thermal resistance of PEEK. Tests carried with various parameters and microscopic investigation of the degradation process allowed to propose an analysis method that can give a satisfactory outcome. Results obtained with carbon fiber/PEEK composite using TGA-based method matched those obtained by chemical etching. Supplementary investigation of PA-based and epoxy resin composites showed the applicability of the method to a wider group of both thermoplastics- and thermoset-based carbon fiber–reinforced composites.

“…One of the great interests in the field of advanced composites is the incorporation of nanomaterials in the polymer matrix. The ideal reinforcement with outstanding properties for polymers such as epoxy resin is multiwalled carbon nanotubes (MWCNTs) although a lot of other reinforcements are also investigated such as nanodiamonds (Zhang et al., 2017), Carbon fiber (Kim et al., 2017) and graphene oxide (Zhang and Cho, 2018). These composites formed by the incorporation of MWCNTs possess good mechanical properties, excellent electrical and high thermal conductivities then the bulk materials (Fu et al., 2010; Chakraborty and Roy, 2012; Vajtai, 2013).…”

Carbon nanotubes (CNTs) are among the strongest and stiffest contender to be used as filler to elevate the properties of epoxy. The aim of this research work is to evaluate the structural, thermal, and morphological properties of multiwalled carbon nanotubes (MWCNTs) hybridized with silver, copper and silver/copper nanoparticles (Ag/CuNP) obtained via chemical reduction of aqueous salts assisted with sodium dodecyl sulphate (SDS) as stabilizing agent. The MWCNTs/NP was further incorporated in DGEBA (epoxy) using ethyl cellulose as hardener. Scanning electron microscopy (SEM) reveals micro structural analysis of the MWCNTs/NP hybrids. The Fourier transform infrared (FTIR) spectra prove the interactions between the NP and MWCNTs. Thermogravimetric analysis (TGA) shows that the MWCNTs/NP hybrids decompose at a much faster rate and the weight loss decreased considerably due to the presence of NP. X-ray diffraction (XRD) confirms the formation of NP on the surface of MWCNTs and X-ray photoelectron spectroscopy (XPS) confirms the full covering of MWCNTs/NP hybrids with DGEBA.

The carbon fiber/epoxy resin (CF/EP) composites have been prepared using CF and the diglycidyl ether of bisphenol‐A (DGEBA) matrix, modified by a new epoxy‐terminated hyperbranched polyether sulfone (EHPES). Compared with CF/DGEBA composite, the modified CF/EHPES composites achieve excellent performances. The tensile strength, modulus, and elongation at break are increased by 19.1%, 7.9%, and 66.7%, respectively. The results are mainly caused by the strong interfacial properties, the interfacial shear strength (IFSS) of CF/7% EHPES composite is increased by 20.7%. Many crosslinking points enhance the mechanical interlocking between the DGEBA/EHPES matrix and CF surface. The strengthened chemical bonding promotes the formation of a higher density crosslinking network. This study provides a strategy for the domestication of large diameter wind turbine blades.
