Variations in the mechanical properties of the glass fibre reinforced polymers were seen when exploring nano fillers such as Multi Walled Carbon Nano Tubes (MWCNTs) and graphene powders for reinforcement. GFRP composites when fabricated with increase in percentage weights of MWCNTs and graphene get better interfacial bonding with the matrix. Nano fillers improve the performance of the composites. This paper deals with the examination and experimental investigations carried out for the prediction of the enhancement of mechanical properties on GFRP reinforced with MWCNTs and graphene powders. GFRP composites were fabricated with variations in the amount of nano fillers in percentage weights of 2%, 4%, 6%, 8% and 10% wt. MWCNTs and graphene powders. The method used for reinforcement of resin with nano fillers was ultrasonication method meant for avoiding voids. A tendency for the mechanical properties to deteriorate was observed when nano fillers added were beyond certain weights of MWCNTs and graphene powders. This could be due to the agglomeration of nano fillers that change the fibre/matrix interface. Graphene nano fillers opts to be better compared to MWCNTs since the fabricated graphene reinforced glass fibre specimens have a better performance than GFRP specimens reinforced with MWCNTs.

Phase-stepping photoelasticity has been used to study the fragmentation of an E-glass fibre in epoxy resin and examine quantitatively the effect of a transverse matrix crack on the stress transfer at an interphase. Unsized glass fibre was coated by plasma polymerisation with a crosslinked conformal film of 90% acrylic acid and 10% 1,7-octadiene. The micro-mechanical response at the fibre-matrix interphase and in the adjacent matrix has been described in detail using contour maps of fringe order. From these, the interfacial shear stress profiles at fibre-break have been calculated.

Fibre Reinforced Composites

The fracture behaviour of long fibre reinforced composites is predetermined mainly by properties of fibre-matrix interface. The matrix prepared by pyrolysis of polysiloxane resin possesses ability to resist high temperatures without significant damage under oxidising atmosphere. The application is therefore limited by fibres and possible changes in the fibre matrix interface. The study of development of interface during high temperature exposition is the main aim of this contribution. Application of various techniques as FIB, GIS, TEM, XRD allowed to monitor microstructural changes in the interface of selected places without additional damage caused by preparation. Additionally, it was possible to obtain information about damage, the crack formation, caused by the heat treatment from the fracture mechanics point of view.

Composites were prepared from recycled polypropylene (RPP), oil palm empty fruit bunch (EFB) and/or glass fibre (GF) using extrusion and injection moulding techniques. Two types of maleic anhydride-grafted polypropylene such as Polybond 3200 and Fusabond P 613 were used to improve the interfacial adhesion between fibres and matrix. The EFB: GF ratio was fixed as 70:30 and fibre loading was considered as 40 wt%. Microwave was used to treat the EFB fibre, which was soaked in a fixed mass concentration (12.5%) of alkali solution at different temperatures (70, 80 and 90°C) for a fixed period of time (60 min) and for different times (60, 90 and 120 min) at a fixed temperature (90°C). A magnetron controller was developed to control the time and temperature accurately for the treatment of fibre. Various characterization techniques such as density, melt flow index, tensile, Izod impact, flexural, field-emission scanning electron microscopy and water uptake testing were performed for the composites. Besides, thermogravimetric analysis and differential scanning calorimetry were also used to evaluate the thermal and crystalline properties of the composites, respectively. Result analyses revealed that microwave-treated fibre-based composites showed improved mechanical and thermal properties. EFB fibres treated at 90°C for 90 min were found to be suitable for better reinforcement into the composite in terms of mechanical, thermal and crystalline properties. Moreover, onset degradation temperature and water absorption properties were also found to be changed apparently due to treatment.
