Increased demand of fibre reinforced plastic (FRP) composites has led to high volumes manufacturing scrap and end-of-life waste. Restrictions on landfill disposal the energy for virgin material production call cost effective composite recycling technology. Unfortunately there is limited integrity environmental related data in literature, help assess life cycle benefits recycling, particularly glass (GFRP). In this work new approaches based bottom-up unit process modelling were used model...

Global increase of composite waste urgently requires innovative recycling technology. The three dimensional cross-linked structure makes melting and remoulding thermoset impossible. In this study, high voltage fragmentation, originally conceived for fracturing rocks was investigated as a potential process recycling. It then benchmarked against its competitor, mechanical investigation covered effectiveness in separating phases, energy demand recyclate quality. work is new contribution to the...

Global rise of composite material demand has led to major legacy problems manufacturing and end life waste. The heterogeneous nature is the main challenge for recycling. In European Union, tighter legislation on landfill, increasing landfill tax loss valuable are driving need development recycling technology. However, environmental benefits may not be optimised due lack high integrity datasets. This study considered mechanical, voltage fragmentation (HVF) chemical methods. New carbon...

The world is neither globally successful in remanufacturing and re-use of products nor recycling waste materials. This requires a combination circular economy management systems, business models novel technologies. There are contrasting views literature regarding for economy. main built on extended producer responsibility the role end users. paper based study South African industry's view models, drivers sustainers, with particular focus composite waste. Cost reduction was found to be...

High demand of glass fibre reinforced thermoset composites has led to manufacturing and end life waste. Mechanical recycling is currently a mature, rapid process in such waste at an industrial scale. Unlike processes, the effect key variables on recyclate quality not well understood. In this study analysis variance was used establish mechanical granulator that influence energy quality. Two different technologies were also compared. This information vital selecting conditions for running...

Composite materials are widely used in various sectors such as aerospace, wind energy and automotive. The high demand especially for thermoset based glass (GFRP) carbon fibre reinforced polymer (CFRP) composite has led to a rise volumes of manufacturing scrap end-of-life products waste. Unlike thermoplastic polymers, polymers have difficulties recycling due their cross-linked nature. In this paper, processes which grouped into mechanical, thermal chemical methods assessed from the...

Abstract Recycled carbon fibre (rCF) is used in various applications as measures to reduce the waste landfill. This study focuses on using rCF powder form injection moulded polypropylene (PP) products. The was treated with 0.5 mol/L and 1.0 nitric acid. tensile flexural properties were evaluated morphological surface of samples characterised scanning electron microscopy (SEM). As result, higher concentration acid increased strength but leads lower strength. Apart from that, environmental...

Abstract In this study, the main objective is to determine effect of recycled carbon fibre (RCF) on mechanical properties thermoplastics composites and associated environmental impacts. Such study important improve strength as previous studies are limited RCF composites, particularly in aspects. compounding stage, extrusion process was carried out by using two different i.e. polypropylene (PP) acrylonitrile butadience styrene (ABS) mixing with RCF. Particle size weight loading were chosen...

Abstract Fused deposition modelling (FDM) process is one of popular 3D printing technologies, especially on polymer materials for a rapid prototyping. The well known its resource saving, with no tooling cost required and minimum energy demand. However, the challenge that performances are highly influenced by selection parameters. From literature, consideration material usage demand in FDM processes still limited. This study used an L9 Taguchi orthogonal array design investigating effect...

Fused deposition modelling performances are dominated by selection of process parameters. Multi objective optimisation is essential in ensuring excellent product mechanical properties, surface quality and resource efficiency. This paper presents a preliminary work based on Taguchi orthogonal array design experiment, considering build orientation, printing angle layer thickness as the input factors. The orientation has significant influence tensile strength while energy consumption time....

Demand for carbon fibre reinforced plastic (CFRP) increases due to its popular demand in sectors such as automotive and aerospace. This leads high volume of manufacturing end life CFRP waste. The challenge is recycle the heterogenous waste utilise recycled (rCF) potential applications, including injection moulding process. However, effect processing parameters type new thermoplastics, filler weight loading particle size on product mechanical properties not well understood. study carried out...

Abstract Additive manufacturing is a process that makes three-dimensional object layer by layer.

Brick is a material to set up construction especially the wall parts. There are various types of bricks. However, focus this study on bricks that consisted recycled plastics. Plastic most used materials daily by humans and often being disposed in landfills causes problems environment. Waste piles pollution issues arise if plastic waste not due its long time or duration taken decompose. non-biodegradable remains as hazardous for more than centuries. can remain earth 4500 years without...
