Enhancement of interfacial properties of basalt fiber reinforced nylon 6 matrix composites with silane coupling agents

Abstract

In this work solution surface treatment was applied for producing basalt fiber reinforced PA6 matrix composites. Beyond scanning electron microscopy, static and dynamic mechanical tests, dynamic mechanical analysis of composites was used for qualifying the interfacial adhesion in a wide temperature range. The loss factor peak height of loss factor is particularly important, because it is in close relationship with the mobility of polymer molecular chain segments and side groups, hence it correlates with the number and strength of primary or secondary bondings established between the matrix and the basalt fibers. It was proven, that the interfacial adhesion between basalt fibers and polyamide can be largely improved by the application of silane coupling agents in the entire usage temperature range of composites. The presence of coupling agents on the surface of basalt fibers was proven by Fourier transform infrared spectroscopy. The best results were obtained by 3-glycidoxypropyltrimethoxysilane coupling agent

Chopped basalt fibres: A new perspective in reinforcing poly(lactic acid) to produce injection moulded engineering composites from renewable and natural resources

“…The surface of the basalt fibres can be modified easily, thus they can be used as reinforcement fibres for composites [25,26]. Deák et al [27] investigated the influence of different coupling agents on the mechanical and thermomechanical properties of basalt fibre reinforced Polyamide 6 (PA6). The tensile, flexural and impact strengths were improved in the highest level by the type of 3-glycidoxypropyltrimethoxysilane sizing.…”

Effect of POSS and chain extender on tensile and fracture properties of neat and short glass fiber reinforced polyamide 6 composites

“…GF reinforced PA6 has a widespread usage in automotive and other industries such as air intake manifolds and sumps in car engines, fuel injection rails, steering column switches, safety parts in sports and snowboard bindings [6,7]. Notwithstanding these widespread application areas, PA6 exhibits notch sensitivity and brittle fracture behavior at high strain rates, especially at low temperatures.…”

Minimisation of Subgrade Thickness Using Natural and Synthetic Additives in Roads

“…The materials for this study includes the soil sample collected from the two village roads of Thanjavur District, soil reinforcement by Coir fibers from coconut and Nylon tyre cord fibers [4]extracted from the waste tyres. Nontraditional stabilizer Bio enzyme was also used as an additive for stabilization.…”
