“…Due to the effect of the carbon atomic lattice defect and C–C stretching vibration of graphite lattice in-plane, the CF possesses D-peak and G-peak. 36 In Raman spectra, the intensity ( I D and I G ) of these two peaks can reflect the crystal perfection ( R ) of CF, i.e. R = I D / I G .…”

A new strategy of recycling and reusing abandoned carbon fiber reinforced plastics (CFRP) is proposed: CFRPs are first fully carbonized to CF reinforced carbon (C/C) preforms, and then are manufactured into high value-added C/C composites. The results showed that the carbon residue rate of epoxy-resin (EP) matrix was fully recovered as the decomposition route of EP matrix was changed by charring agent. The recycled CF (rCF) was not markedly oxidized or thermally damaged, and possessed comparable properties with those of the virgin CF (vCF) after pyrolysis. The pyrolytic char had no obvious negative effect on the densification efficiency of the rCF reinforced carbon (rCF/C) composites. Both of the rCF/C and vCF reinforced carbon (vCF/C) composite bodies were quite dense, and exhibited almost no difference in their microstructures. The rCF/C and vCF/C composites therefore had quite close interface bonding strength (12.6 MPa and 13.0 MPa, respectively), and bending strength (106.4 MPa and 111.5 MPa, respectively). Furthermore, the rCF/C composites possessed comparable ablative rate with that of the vCF/C composites. The rCF/C composites derived from abandoned CF/EP composites present a great potential to be used as substitutes for vCF/C composites owing to their indistinguishable properties.

“…Although lower than the conventional brake pad, the overall result is good as pads based on carbon nanomaterials do not have high thermal stability. Guo et al investigated the characteristics and frictional performance of C-C/SiC materials made from recycled carbon fiber felt and found that they hold high potential for utilization as alternative commercial brake pad substances [93].…”

The proper functioning of automotive brake pads is of utmost importance to ensure the safety of passengers. Therefore, brake pad materials must be chosen with utmost precision and care to ensure their optimal functioning for long durations. Through a thorough literature review, it is found that the materials used currently for this purpose pose multiple discrepancies. Therefore, it is imperative to shift our focus towards nanomaterials, as they are one of the essential novel materials in this field. This study discusses the multiple constituents used in commercial brake pads, their role in improving and stabilizing their operation, and their desired properties to achieve optimal functioning. Parallelly, this study also reviews some of the potential organic and carbon nanomaterials that could prove to provide tough competition to currently utilized materials for brake pad applications. From this review, the major future commercial brake pad materials obtained include the likes of banana peel powder, crab shell powder, coconut fibers, stark corn fibers, metal oxide composites, metal nitride composites, multiwalled carbon nanotubes, and hybrid nanocomposites. These materials are studied on the basis of their performance under high-frictional force applications and analyzed by considering their mechanical, chemical, thermal, and tribological properties. Carbon nanotube-based composites showed improved tribological and braking performances making them more attractive than the materials in commercially available brake pads. In addition to these, the effects of usage of such nanomaterials on the environment and health are reviewed, in order to understand the feasibility of utilization of nanomaterials in automotive brake pad applications. From this analysis, this work suggests that there are a variety of nanomaterials that prove to be capable of automotive brake pad applications and, with further research and technological developments, would prove to be an asset to the automotive brake pad industry.

Huntite (CaMg3(CO3)4) is a calcium magnesium carbonate mineral and is a mineral in the dolomite group. Although studies on Huntite's flame retardant raw material feature stand out, it is used in the paint industry, and the industrial sectors such as plastics, pol-ymers, special rubbers, and pharmaceuticals. In this study, experiments were carried out by producing brake pad samples in different mixing ratios from huntite mineral and glass fiber, kaolin, graphite, phenolic resin, and rubber powder to be used for brake pads in the automotive industry. Friction coefficient and wear rate which is an important fea-ture for the produced pad samples were measured in the brake pad testing device. Ac-cording to the Archimedes principle, the specific gravity and disc roughness values formed by the brake pad samples on the disc were measured with a roughness tester. According to the measured values, the highest average friction coefficient was obtained in the A45 sample, the minimum wear value was obtained in the A10 sample, and the minimum roughness change was obtained in the A25 sample.
