Abstract
Improvement in mechanical properties of fibre-reinforced polymer composites through proper matrix modification has emerged as the significant trend in recent advanced technology. Dispersion of nanofillers in the matrix results in ultra-light weight, high strength, impact resistant and durable structures. In the current investigation, effect of the addition of varying percentages (0, 1, 3, 5 and 7 wt.%) of low-cost nanoclay to the unsymmetrical carbon/glass (C2G8) hybrid composites on mechanical, tribological and low-velocity impact (LVI) behaviour were investigated. Using traditional hand lay-up techniques, nanocomposite specimens were prepared. The results revealed that C2G8 hybrid composite with 5 wt.% loading of nanoclay possessed maximum hardness (35 HV), flexural strength (494 MPa), impact strength (Izod (119.022 kJ m−2), Charpy (563.922 kJ m−2)) and minimum specific wear rate (19.6 × 10−3 mm3 Nm−1) in comparison with other hybrid combinations. LVI test also revealed enhanced energy absorption (112.46 J) for hybrid nanocomposite against plain C2G8 hybrid composite. Furthermore, the damage depth and areas were observed by visual inspection and scanning electron microscope to account for best possible structure–property relationship. Developed hybrid nanocomposite may be considered as a suitable material for various automotive applications.
期刊介绍:
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
