Pineapple leaf fibers with diameters of 43 ± 0.1 µm were treated by two different approaches: the alkaline treatment and the combination of the steam explosion and alkaline treatment. The observations revealed the steam explosion process efficiently provided 3.4 µm diameter fibers with a less amount of lignin and a higher proportion of cellulose, compared with the alkaline-treated fibers. The steam-exploded fibers showed higher crystallinity and more thermal stabilities than the alkaline-treated fibers. No structural change from cellulose I to cellulose II was detected from both treated pineapple leaf fibers. Subsequently, all-cellulose composite laminates were prepared from these two types of treated pineapple leaf fibers mats. The higher tensile strength and modulus were obtained from the steam-exploded pineapple leaf fibers composite laminates due to larger surface areas of the fibers interacted with the cellulose matrix. Fracture morphology of the composites was studied after tensile deformation. The combination mechanism of fiber breakage and fiber pull-out deformation was observed from the steam-exploded pineapple leaf fibers composite laminates, whereas only fiber pull-out mechanism was found from the alkaline-treated pineapple leaf fibers composite laminates. The fiber width and amounts of the matrix filling in pores in a mat were found to dominate the mechanical properties of the all-cellulose composites.

“…Crosslinking becomes the prevalent mechanism upon irradiation resulting in improved mechanical properties of the WH blend matrix‐filler system. Literature review suggests that upon irradiation, radical formation in the matrix and filler leads to cross linking between the two materials leading to improvement in the rigidity of network that contributes in significant enhancement of tensile and flexural strength .…”

Disposal of polyethylene used as carry bags is the greatest challenge increasing day by day. Composite materials were prepared by mixing Fly ash (FA) and nanostructured fly ash (NFA) from thermal power station as filler and blends of Waste polyethylene (WPE)(-carry bags) collected from municipal solid waste (MSW) with virgin high-density polyethylene (HDPE) as matrix. Different modifications were induced to improve the overall properties of these composites. At first, the WPE/HDPE blend matrix was modified by grafting with maleic anhydride (MA) and the composite prepared with FA/NFA. Then, the WPE/HDPE-FA/NFA composite as a whole was treated with electron beam irradiation at 250 kGy radiation dose and finally the FA/ NFA filler was treated with radiation dose of 250 kGy and the composite prepared. Significant enhancement in tensile strength, flexural strength, flexural modulus, and hardness are observed for MA modified and irradiated composites, the increase being more prominent in irradiated composites. Furthermore, an increase in storage/loss moduli with enhanced thermal stability was observed with the addition of FA/NFA and upon modifications. The analysis of the tensile fractured surfaces by scanning electron microscopy was in well correlation with the mechanical properties obtained. In summary, after analyzing the effects of the three different modifications on mechanical, dynamic mechanical and thermal properties, the irradiation on to the WPE/ HDPE-FA/NFA composites investigated was selected as the most appropriate for future applications.

The impact of varying thickness on the tension, bending, as well as shear failure shear characteristics of unprocessed woven kenaf with charcoal textile reinforced polyester hybrid compounds has already been empirically examined. Handmade lay-up hybrid composites are created in a mould as well as dried under mild compression for 6 minutes before drying at room temperature. Each hybrid composite had a maximum of five plies, with the amount and location of insulating material varying to provide five different layering patterns. For comparability, a grouping of any and all kenaf laminates has also been created. The increased fibre weight percentage was kept constant at 40%. ASTM specifications were followed for sample creation and testing. The MES 610 Materials Simulation Environment was put through its paces using the automated purposeful sampling software Test Performs. The findings demonstrate that incorporating synthetic fibres as severe diamond flanges may drastically enhance the characteristics of kenaf hybrids. Bending and interlaminar shear characteristics are more affected by layering arrangement than tension qualities. An analysis of all of the quality issues discovered that the hybrids laminated with two different charcoal flanges along both sides are indeed the perfect pairing with such a decent mix of attributes and price.
