Abstract
Abstract This work investigates the incorporation of disposed carbon microfibres (CMF) obtained from the cutting process of laminate composites into epoxy polymers at different mass fractions (0, 2.5, 5, 7.5 and 10wt%). The elastic modulus and strength under tensile, compressive, flexural loads and impact resistance are investigated via Analysis of Variance (ANOVA). The tensile (compressive) modulus progressively increases up to 36.6% (28.6%) with the inclusion of CMF. The inclusion of 5wt% CMF results in an increase of 27% (19%) in tensile (compressive) strength. The flexural strength also increases 28.6% when 10wt% CMF is added. CMF waste leads, however, to a dramatic decrease (approx. 50%) in impact resistance attributed to the increase in stiffness.

Abstract The increasing utilisation of carbon materials increases the waste generation. Therefore, it is necessary to analyse recycling alternatives. In this research, carbon powder wastes obtained from the cutting process of laminate composites have been incorporated into epoxy matrix phase in order to improve the mechanical characteristics. Physical and mechanical properties, hardness, abrasion, erosion and thermal behaviour have been analysed. Results show that carbon powder wastes incorporat...

Abstract Composite materials are used in a wide range of applications such as automotive, aerospace and renewable energy industries. But they have not been properly recycled, due to their inherent nature of heterogeneity, in particular for the thermoset-based polymer composites. The current and future waste management and environmental legislations require all engineering materials to be properly recovered and recycled, from end-of-life (EOL) products such as automobiles, wind turbines and aircr...

The objective of this study is to develop a new method of manufacturing glass fiber reinforced epoxy composites and to quantitatively show that the properties of such a new material are superior to that of a conventional fiber reinforced polymer composite of the same material base composition. To achieve this objective, the glass fiber (GF) reinforced epoxy composite samples are prepared in four different ways: Method A, using ‘clean’ GF as the reinforcement (i.e., with no modification or additi...

Abstract This work describes the physical and mechanical characterization of unidirectional [0]12 and crossply [(0/90)3/ 0 ¯ ]S flax fibre reinforced composites fabricated in autoclave using a prepreg flax tape impregnated with fire retardant epoxy polymer. Tensile, bending and impact properties are evaluated along the longitudinal and transverse fibre directions. The tensile-tensile fatigue behaviour is characterised along the fibre direction. Physical and specific properties are also assessed ...
