Effect of combined micro and nano silicon carbide particles addition on mechanical, wear and moisture absorption features of basalt bidirectional mat/vinyl ester composites

Abstract

Basalt fiber reinforcement in polymer composites has recently become very competitive to the routinely used synthetic fiber reinforcements. In the present work, composite specimens were prepared with basalt fiber mat reinforcement in vinyl ester matrix along with varying quantity of the micro and nano silicon carbide (SiC) filler particle ranging from 1 to 5 wt% in combination. Tribological and water absorption properties of the developed hybrid composites were tested to ascertain its potential for commercial applications. The specimen made of SiC particle addictive combination of 3 wt% nano and 3 wt% micro particle exhibited better mechanical characteristics and this mechanical advantage declines beyond 3 wt% SiC filler addition due to agglomeration and poor dispersion of filler particles in the hybrid composite. The microstructural investigation done via scanning electron microscopy reveals the modes of failure, where better pullout resistance was displayed by the fiber bonding characteristics with the filler and vinyl ester matrix up to 3 wt% nano and 3 wt% micro SiC filler content. Similarly, the tribological characteristics of the composite specimen for the optimum filler content specimen were superior in comparison with other combinations. Moreover, the water absorption features of the developed hybrid composites were within the acceptable limits for marine and structural applications.

Influence of SiC nanoparticles on properties of alkali‐treated areca fruit husk fiber/hybrid polymer composites

“…The damaged surface of AAFHF/SiC/UPR hybrid composite specimens undergone rupture when subjected to tensile and wear loads were examined through scanning electron microscope (SEM). The failure phenomenon of the composite specimens at different type of loads was understood from the obtained SEM images 29 . The SEM images were obtained from thin layer of platinum‐coated composite specimens which inhibit charge gathering at 3 kV electron beam voltage.…”

Extensive characterization of pretreated/enzyme treated cellulosicAreca catechu L. peduncle fiber for polymer composite applications

“…5,6 Weaker interfacial bonding characteristics between the reinforcement and the matrix leads to inferior mechanical characteristics of developed composite. 7 In order to enhance the mechanical characteristics of polymer composites with natural fiber reinforcement, the surface texture of natural fiber reinforcements can be altered by physical or chemical means. The adaptation of physical methods to alter the surface texture of natural fiber reinforcements tends to deteriorate its mechanical characteristics; hence mostly chemical methods were adapted for surface modifications.…”

Comprehensive characterization of raw and treated pineapple leaf fiber/polylactic acid green composites manufactured by 3D printing technique

“…Natural fiber reinforced polymer composites occupies a considerable place in automobile, structural and aerospace applications due to its partial biodegradability, light weight, sufficient specific strength and low cost. [1][2][3] The increasing cost of petroleum based products in recent times and its non-ecofriendly nature has made researchers and engineers to think of an alternate material for petroleum based polymer matrix used in polymer composites. To improve the sustainability of the composite material considering the stringent environmental regulations enforced by the government and to comply with the application requirements it is crucial to identify a green material with novel manufacturing technique suitable for mass production for the same.…”
