Study of the surfactants role in natural fibres reinforced composites for structural applications

In this study, hemp fibres were used as reinforcements in polypropylene (PP) resin to form composite materials for structural applications. Adhesion between the fillers and holding matrix was enhanced using alkalisation, KMnO4treatments respectively on the fibre surface thus developed. Spectroscopic...

Description
Summary:In this study, hemp fibres were used as reinforcements in polypropylene (PP) resin to form composite materials for structural applications. Adhesion between the fillers and holding matrix was enhanced using alkalisation, KMnO4treatments respectively on the fibre surface thus developed. Spectroscopic analysis such as Fourier transforms infrared (FTIR) and scanning electron microscope (SEM) was carried out to determine interferential adhesion and homogeneous distribution of fibres in the holding matrix. Based on the results obtained fibres treated with both NaOH and KMnO4 treatment showed better mechanical properties than the treatments done in isolation. Among the results obtained fibres specifically treated with specific co mposition of 5% NaOH an d 0.6% KMnO4 exh ibited better mechanical properties compared to those with treated and untreated fibre composite samples.
