Abstract

Abstract Glass fibre (GF), nanoclay (NC) and hybrid composites compatibilised with maleic anhydride polypropylene (MAPP) were prepared by extrusion and injection moulding. The fourier transform infra-red spectra revealed the characteristic absorption peaks of MAPP in the compatibilised GF and NC composites. A decrement in the peak intensity of X-ray diffraction patterns of NC composite was obtained as the MAPP content increased indicating a partial exfoliation of NC. The thermogravimetric analysis showed that the incorporation of MAPP into hybrid composites reduced the thermal stability of the material. The dynamic mechanical analysis showed an increase in the storage modulus in the hybrid composites with lower content of MAPP due to the enhancement in the interfacial adhesion between the GF, NC and PP matrix.

Highlights

Polypropylene (PP), one of the most exploited the optimum mechanical properties
To cope with some limitations of PP, a number of reports have been published on for example, low stiffness and low strength, and to expand the use of maleic anhydride grafted polypropylene (MAPP). Their applications in different sectors, inorganic fillers, such as compatibiliser for PP composites, there is very little as glass fibre (GF), carbon nanotubes and clays, are often information available regarding the effect of compatibiliser added when processing the polymer composites, which in the hybrid composite systems[15]
Glass fibre reinforced PP composite is in PP/GF/NC hybrid composites prepared through a melt quite attractive because of their ease of fabrication, superior processing method is investigated

Summary

Introduction

Polypropylene (PP), one of the most exploited the optimum mechanical properties. the extent thermoplastic resins in the composites, alloy and blends to which fillers can vary the properties of the resultant industries[1], possesses outstanding properties like low composite parts is depends on the nature of adhesion between density, good abrasion resistance and excellent electrical the filler and the matrix. To cope with some limitations of PP, a number of reports have been published on for example, low stiffness and low strength, and to expand the use of maleic anhydride grafted polypropylene (MAPP) Their applications in different sectors, inorganic fillers, such as compatibiliser for PP composites, there is very little as glass fibre (GF), carbon nanotubes and clays, are often information available regarding the effect of compatibiliser added when processing the polymer composites, which in the hybrid composite systems[15]. For this reason, in normally combine the advantages of their constituent phases[3]. Using nano reinforcements in a GF reinforced PP matrix, Cui et al.[14] observed that the addition of 2 wt% nano-ZnO in 40 wt% GF composite gave
