“…On the other hand, oxygen treatments have the advantage of increasing the interfacial adhesion and wetting properties of the fiber while attaching various functional groups such as carboxyl (–COOH), carbonyl (–CO), and hydroxyl groups (–OH) [ 37 , 38 ]. This can be interpreted as a method to enable better interfacial adhesion and interactions between the CNTs and the epoxy matrix of multi-scale composites, providing excellent mechanical properties [ 39 , 40 , 41 ].…”

In this study, nano-scale fillers are added to epoxy matrix-based carbon fibers-reinforced composites (CFRPs) to improve the mechanical properties of multi-scale composites. Single-walled carbon nanotubes (SWCNTs) used as nano-scale fillers are treated with atmospheric-pressure plasma to introduce oxygen functional groups on the fillers’ surface to increase the surface free energy and polar component, which relates to the mechanical properties of multi-scale composites. In addition, the effect of dispersibility was analyzed through the fracture surfaces of multi-scale composites containing atmospheric-pressure plasma-treated SWCNTs (P-SWCNTs) under high load conditions. The fillers content has an optimum weight percent load at 0.5 wt.% and the fracture toughness (KIC) method is used to demonstrate an improvement in mechanical properties. Here, KIC was calculated by three equations based on different models and we analyzed the correlation between mechanical properties and surface treatment. Compared to the composites of untreated SWCNTs, the KIC value is improved by 23.7%, suggesting improved mechanical properties by introducing selective functional groups through surface control technology to improve interfacial interactions within multi-scale composites.

“…The interfacial bonding between the carbon fiber and the matrix is the critical factor determining the macro-performances of carbon fiber/ resin composites and needs to be clarified. VASTM [46,47] ***GO-SiO 2 -CF The presence of GO/SiO2 could increase the surface roughness and wettability of CFs, which significantly enhances the interfacial strength of CFs epoxy composites, and specifically, compared to untreated-CF composites, the IFSS, ILSS, and flexural strength of CF-L5 epoxy composites revealed the highest value, which increased by 86.1%, 89.3%, and 30.4%, respectively.…”

The present review paper focuses on the current state of the art of the alumina-silicate ceramics and surface modifications of ceramics dedicated as fillers in composites with carbon fiber. The use of aluminum-silicates in the form of a cenosphere due to their outstanding properties, i.e., low density, high hardness, and total chemical inertness seem to be promising in biomaterial engineering applications. First of all, the possibilities of the composites application in orthopedic and prosthetic implantology. The following section discusses problems with the use of aluminum silicate ceramics and their processing. Subsequently, in the paragraphs to follow, the possibilities of modifying the surface with chemical methods are discussed, among others oxidation, chemical methods like ionic liquids etching, silanization, and physical processes i.e., thermal treatment. In the summary, the directions of development of ceramic-carbon fiber composites and the primary deficiencies of these composites on which to focus on and solve are discussed.

“…In fact, Borooj et al found that plasma treatment increased the roughness of the surface leading to enhanced mechanical interlocking and improved composite interlaminar shear strength (ILSS), due to the inclusion of different polar functional groups such as carboxyl and hydroxyl on the surface of carbon fibers [ 12 ]. In addition, a detrimental effect of long exposure time and high power plasma was observed owing partly to damage of the carbon fibers surface and, hence, decrease of the ILSS of treated carbon fiber composites [ 14 ].…”

Hydrophobic surfaces are highly desired for several applications due to their exceptional properties such as self-cleaning, anti-icing, anti-friction and others. Such surfaces can be prepared via numerous methods including plasma technology, a dry technique with low environmental impact. In this paper, the effect of a one-step sulfur hexafluoride (SF6) plasma treatment upon the low velocity impact behavior of basalt/epoxy composites has been investigated by using several characterization techniques. A capacitive coupled radiofrequency plasma system was used for the plasma surface treatment of basalt/epoxy composites, and suitable surface treatment conditions were experimentally investigated with respect to gas flow rate, chamber pressure, power intensity, and surface treatment time by measuring the water droplet contact angle of treated specimens. The contact angle measurements showed that treating with SF6 plasma would increase the hydrophobicity of basalt/epoxy composites; moreover, the impact results obtained on reinforced epoxy basalt fiber showed damage in a confined area and higher impact resistance for plasma-treated basalt systems.
