“…The IFSS with the IH-rGF prior to any treatment approximates that reported by Nagel after thermal conditioning [19]. The new, unsized glass fibres, exhibit significantly weaker interfacial adhesion than the IH-rGF and closely matches that reported by Thomason [32] and Min et al [33]. With a fluidised bed temperature of 500 °C, the organic portion of the silane coupling agent present on the fibres in the recyclate will decompose during recycling [13]; however, the siloxane network which is deposited on the fibre surface will remain.…”

The value of recycled glass fibres is reduced significantly due to loss in strength and surface functionality during recycling. This work investigates the potential of a variety of treatments to regenerate the strength and surface functionality of glass fibres recycled from retired wind turbine blades using an in-house developed fluidised bed process. It was found that soaking in hot NaOH solution could provide approximately a 130% increase in the tensile strength of recycled glass fibre; concluding that changes to surface morphology due to etching was the restrengthening mechanism. The interfacial adhesion between recycled glass fibre and polypropylene was also examined. A significant reduction in interfacial shear strength was observed after recycling which is attributed to the loss of original sizing after recycling. Regenerating the interfacial shear strength between recycled glass fibre and polypropylene proved challenging with the use of aminopropyltriethoxysilane coupling agent alone, however, a twofold increase in the interfacial shear strength was attained by modifying the polypropylene matrix with maleic anhydride. It was found that NaOH and silane treatments restored the interfacial shear strength between interfacial shear strength and epoxy to that obtained with as received glass fibres. This work shows that substantial improvements in recycled glass fibre strength and fibre-polymer adhesion can be achieved after utilising various regeneration treatments, in turn producing recycled glass fibres with significantly enhanced reinforcement potential.

The objective of this study is to analyses the Agave Cantula Roxb tensile and bending strength. The analysis was further done to observe the sustainability utilization the Agave Cantula Roxb fiber as a composite strengthener for fishing boat hulls. The research was carried out at the metallurgy mechanical engineering laboratory, Engineering Faculty, Indonesia Paul Christian University, Makassar. The method used is making a specimen with a 0%, 20%, 30%, 40% and 50% fiber composition, while the catalyst composition as a hardener is about 10%. To determine the material mechanical strength, a tensile test was carried out where the specimen dimension was based on the ASTM D3039 international standard. While for the bending test, the specimen dimension was based on the ASTM D790-03. From the test result it is indicated that not all composite specimen composition can be used as ship hulls material. Based on the standard required by the Indonesian Classification Bureau, the composite tensile strength standard (σt) is about 10 kf/mm2 and a bending strength standard (σb) of 15 kgf/mm2. Based on standard required, the composite condition that fulfilled the requirements is the 50% fiber which has a tensile strength of σt = 11,8 kgf/mm2 and a bending stress σb = 25,41 kgf/mm2.
