Hybrid composites based on sisal fibers and silica nanoparticles

Abstract

The progress in establishing new classes of biocomposites has led to potential applications in the automotive, aerospace, and construction industries because of their life cycle properties, low cost, lightweight, nonabrasive, and moderate mechanical strength. The heterogeneity of natural fibers plays an important role in the fiber-matrix adhesion, therefore affecting the mechanical performance and the durability of the composites. This work has described the manufacturing, characterization, and testing of hybrid composites reinforced with sisal fibers and silica nanoparticles. A full factorial design was performed to identify the effects of fiber treatment, fiber orientation and nanosilica inclusion factors on the physical and mechanical properties of hybrid composites. Composites made with unidirectional untreated fibres and silica nanoparticles (2 wt%) provided higher impact resistance. In contrast, the highest strength and stiffness values and the lowest overall porosity were achieved when unidirectional treated fibres with 2 wt% of silica inclusions were considered. POLYM.

Hybrid glass fibre reinforced composites containing silica and cement microparticles based on a design of experiment

“…In fact, the poor tolerance to accidental low velocity impact of composite laminates is still a limitation to their use in many applications. An improvement of impact resistance by adding particle inclusions along with no degrading of flexural properties has been reported in the literature [12][13][14].…”

Novel fibre metal laminate sandwich composite structure with sisal woven core

“…The use of natural fibres in FMLs such as mixed jute/carbon fibres (Vasumathi et al, 2013) and bamboo fibres (Zhang et al, 2000) has been shown to be successful in different applications (Sinmazçelik et al 2011). A new generation of hybrid sisal fibre composites reinforced with micro and nano particles has been investigated for industrial applications Vieira et al, 2016;Ramzy et al, 2014). This work investigates the mechanical properties of FMLs containing an innovative core made of sisal fibre reinforced composite (SFRC).…”

Impact of hybrid composites based on rubber tyres particles and sugarcane bagasse fibres

“…In the present work, several preliminary tests were conducted to achieve a suitable treatment time in which the fibre was sufficiently modified to increase adhesion without excessive degradation of the fibres. This adapted procedure was also reported by Vieira et al [19]. The mercerization treatment consisted of immersing the fibres in a 10% NaOH (w/v) solution for 1 hour at room temperature.…”
