“…On the other hand, the hybrid + MWCNT composite with 500 and 1000 h of exposure showed no significant variation in tensile strength when compared to the unexposed hybrid + MWCNT composite. This can be explained by the fact that nanoparticles can absorb UV rays 43 .

The main objective of this study was to investigate the effect of aging by ultraviolet radiation and water spray on the mechanical properties of natural fiber and hybrid composites. Pure jute, hybrid jute/glass, and glass fiber‐reinforced composites were fabricated. All these types of composites were further modified with 0.6 wt% of multi‐walled carbon nanotubes (MWCNTs) and their mechanical behavior was compared to the unmodified specimens. Tensile and flexural tests were used to measure the mechanical properties of unaged (control) and aged specimens. A scanning electron microscopy analysis was used to examine the fracture surfaces of the specimens tested. It was found that the aging process affected the mechanical properties of the composites studied in different ways. For jute and jute + MWCNT composites the properties decreased with increased exposure time. The hybrid jute/glass composites (unmodified and MWCNT modified) were less affected by aging and showed an insignificant change in tensile strength. The hybrid + MWCNT composites, showed an increase of approx. 7% in Young's modulus (1000 h) and 9% (500 h) and 17%, (1000 h) in flexural modulus when compared to the unexposed specimens. The MWCNTs had a positive effect on the mechanical properties of the glass + MWCNT aged samples.

“…Conventional synthetic fibre-reinforced composites have been a popular choice for transport and construction industries for the last five decades as a consequence of their high strength-to-weight ratios. However, recent pressures towards a circular economy based on increased sustainability and recyclability of the products, etc., has focused interest on the use of natural fibre reinforcements, as well as biopolymer matrices [ 1 , 2 ]. The usage of such natural fibres has gained momentum due to their advantages in terms of low densities, highly specific strengths and moduli, and biodegradability, compared to glass, for example [ 3 , 4 , 5 ].…”

“…The usage of such natural fibres has gained momentum due to their advantages in terms of low densities, highly specific strengths and moduli, and biodegradability, compared to glass, for example [ 3 , 4 , 5 ]. Natural fibres may also be used as a secondary reinforcement as hybrids with other synthetic fibres [ 1 , 2 ]. The mechanical properties of composites reinforced with lignocellulosic fibres (such as jute, sisal, flax and hemp), while not sufficiently high for structural applications, are high enough to replace glass fibre-composites for low-cost, low strength applications [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

“…For marine applications ageing in seawater, usually as NaCl solution is undertaken. While some studies have taken place on the effects of sea water and acidic and alkaline environments by immersing natural fibre-composites in those solutions [ 1 , 20 , 23 , 24 ], there is still a gap in the understanding of their effects on both physical and chemical changes in individual components, which are determining factors for the mechanical and thermal properties of the composites.…”

Effects of Water and Chemical Solutions Ageing on the Physical, Mechanical, Thermal and Flammability Properties of Natural Fibre-Reinforced Thermoplastic Composites

Biocomposites comprising a combination of natural fibres and bio-based polymers are good alternatives to those produced from synthetic components in terms of sustainability and environmental issues. However, it is well known that water or aqueous chemical solutions affect natural polymers/fibres more than the respective synthetic components. In this study the effects of water, salt water, acidic and alkali solutions ageing on water uptake, mechanical properties and flammability of natural fibre-reinforced polypropylene (PP) and poly(lactic acid) (PLA) composites were compared. Jute, sisal and wool fibre- reinforced PP and PLA composites were prepared using a novel, patented nonwoven technology followed by the hot press method. The prepared composites were aged in water and chemical solutions for up to 3 week periods. Water absorption, flexural properties and the thermal and flammability performances of the composites were investigated before and after ageing each process. The effect of post-ageing drying on the retention of mechanical and flammability properties has also been studied. A linear relationship between irreversible flexural modulus reduction and water adsorption/desorption was observed. The aqueous chemical solutions caused further but minor effects in terms of moisture sorption and flexural modulus changes. PLA composites were affected more than the respective PP composites, because of their hydrolytic sensitivity. From thermal analytical results, these changes in PP composites could be attributed to ageing effects on fibres, whereas in PLA composite changes related to both those of fibres present and of the polymer. Ageing however, had no adverse effect on the flammability of the composites.

Increased recycling of plastics is an essential step toward a more sustainable use of materials, where some of the most challenging fractions are engineering materials and composites. Used pump houses prepared from glass fiber (GF)‐reinforced blends of polyphenylene oxide (PPO) and high‐impact polystyrene (HIPS) obtained through a take‐back scheme (take‐back, TB) were characterized and shredded for use in the preparation of new composites by injection molding. Initial degradation was observed on the surface of the TB parts; however, the core of the material was unaffected. Mechanical reprocessing of regrind and virgin material showed a reduction of tensile strength already at 10% regrind, which was attributed to fiber length reduction during reprocessing. At the same time, Young's modulus and extension at break were largely unaffected, confirming that 25% of TB could be included without any additional loss of properties. As a worst‐case scenario, tests with extensively degraded material showed that Young's modulus and tensile strength would ultimately be reduced with an increasing amount of heavily degraded material and that a balance would have to be found between loss of properties and recycled content for heavily degraded material.
