“…In addition to van der Waals binding and chemical bonding, CNTs also provide mechanical interlocking between the matrix and the fibers, increased interfacial friction, and local strengthening of the matrix at the interface. Cui et al [22] showed that COOH-MWCNTs improved homogeneous dispersion and the interfacial adhesion between nanoparticles and epoxy. Figure 1 displays the chemical structure of epoxy and its potential interaction with COOH-MWCNTs.…”

“…Beyond a certain content of CNTs, they aggregate easily and function as a defect in the composite, contributing to stress concentrations and weakening the composite. Therefore, during composite fabrication it is necessary to avoid agglomerations as well as to maintain stable dispersion to avoid secondary agglomeration during curing [22]. Agglomerations cause CNTs to have a very low solubility in most solvents, often resulting in a non-homogenous dispersion within a surrounding matrix.…”

Carbon fiber reinforced polymer (CFRP) laminates exhibit limited fracture toughness due to characteristic interlaminar fiber-matrix cracking and delamination. In this article, we demonstrate that the fracture toughness of CFRP laminates can be improved by the addition of multi-walled carbon nanotubes (MWCNTs). Experimental investigations and numerical modeling were performed to determine the effects of using MWCNTs in CFRP laminates. The CFRP specimens were produced using an epoxy nanocomposite matrix reinforced with carboxyl functionalized multi-walled carbon nanotubes (COOH-MWCNTs). Four MWCNTs contents of 0.0%, 0.5%, 1.0%, and 1.5% per weight of the epoxy resin/hardener mixture were examined. Double cantilever beam (DCB) tests were performed to determine the mode I interlaminar fracture toughness of the unidirectional CFRP composites. This composite material property was quantified using the critical energy release rate, GIC. The experimental results show a 25%, 20%, and 17% increase in the maximum interlaminar fracture toughness of the CFRP composites with the addition of 0.5, 1.0, and 1.5 wt% MWCNTs, respectively. Microstructural investigations using Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) verify that chemical reactions took place between the COOH-MWCNTs and the epoxy resin, supporting the improvements experimentally observed in the interlaminar fracture toughness

Abstract.A simple and efficient method was presented for chemical functionalization of multi-walled carbon nanotubes (MWCNTs) with vitamin B 1 . Poly(ester-imide) (PEI) based nanocomposites were prepared by the incorporation of different amounts of modified MWCNTs (5, 10, 15 wt%) into a chiral and biodegradable PEI by solution blending and ultrasonic dispersion methods. The chiral PEI was produced by a step-growth polymerization of chiral diacid with 4,4!-thiobis(2-tertbutyl-5-methylphenol). Spectroscopic and microscopic techniques were used to examine the chemical structure, morphology and thermal stability of the functionalized MWCNTs and the obtained nanocomposites. The microstructure study revealed the homogeneous dispersion of modified MWCNTs throughout the PEI matrix. Thermogravimetric analysis results confirmed that the heat stability of the prepared composites was improved compared to the pure PEI.
