“…Acid hydrolysis treatment on AFAH fibers results in a rougher and more uniform fiber surface [29,32,55,62,63]. This increased roughness is advantageous as it helps to form an interlock between the fibers and the matrix, thereby enhancing the mechanical strength of the composite material [25,[34][35][36].…”

“…By eliminating oil, wax, and other contaminants, the surface of the fibers undergoes a transformation to a rougher and more uniform [29,32], which increases surface roughness and facilitates the formation of physical interlocking between the fibers and the matrix. This process enhances the mechanical strength of the composite [35][36][37][38]. It substantially enhances the compatibility of the fibers with the polymer matrix in the composite, making them more effective for use in a wide range of applications, from technical textiles to automotive and construction components.…”

Recently, abaca fibers have become the focus of specialized research due to their intriguing characteristics, with their outstanding mechanical properties being a particularly notable. In the conducted study, the abaca fibers underwent a preliminary treatment process involving an alkaline solution, which was composed of 0.5% sodium hydroxide (NaOH) and 50% acetic acid (CH 3 COOH). This process entailed immersing each fiber in the solution for a period of one hour. This treatment led to a 52.36% reduction in lignin content compared to the levels before treatment, resulting in a dramatic decrease in the full width at half maximum (FWHM) in the XRD spectra from 1.13 to 0.13. This change indicates that the fibers became more crystalline following the treatment. The abaca fibers were also characterized using BET (Brunauer Emmett Teller) measurements, which revealed that the average pore length ranged from 33-49 nm and the surface area was between 13-28 m 2 •g −1 . The morphology of the abaca fiber after alkali an hydrolisis treatment (AFAH) appeared rougher and more uniform. DMA measurements revealed a significant rise in the storage modulus of the single fiber post-treatment, with dependencies on both frequency and temperature. AFAH exhibited an optimal absorption coefficient of α = 0.9 for frequencies above 2500 Hz. The combined effect of alkalization and hydrolyzation treatments, while resulting in an enhancement in the mechanical properties of the fibers, also reduced high-intensity noise produced by sources such as machinery, aircraft takeoffs and landings, etc., across a broader working frequency range.
