“…The behaviour of the double-layered ligno-cellulosic Luffa (ridge gourd) fiber belonging to Cucurbitaceae family were studied and chemical, spectral, and thermal analysis of this fiber were carried out before and after alkali treatment. The thermal degradation of the fiber was reported at 260 °C, which is the initial degradation temperature of this fiber [7].…”

This study focuses on enhancing the static and dynamic mechanical behaviours of vinyl ester matrix using surface modified Luffa fibers. The density of Luffa fiber, which belongs to Cucurbitaceae family, is 1.2 g/cc. The Luffa (Ridge gourd) vegetable was dried in sun-light and the required fiber layers were then obtained by using manual extraction process. The fiber layers were then treated with alkali (5% of NaOH) solution at ambient temperature (28o C) for 24 h. From the SEM images, it can be inferred that the chemical treatment did not degrade the fiber surface and retained its reinforcing nature. The Luffa fiber reinforced vinyl ester composites were developed by hand layup technique by varying the number of fiber layers (1, 2 and 3). The morphological and mechanical behaviours of the developed composites were analyzed as per ASTM standards and compared with pure resin. The static and dynamic mechanical properties of vinyl ester composites exhibited significant improvement with fiber surface treatment and increase in number of fiber layers. Among the different composites tested, the composite specimen with three layers of alkali treated fiber exhibited the highest tensile strength (18.88 MPa) compared to untreated fibers (16.83 MPa). The improvement in properties of Luffa fiber reinforced composites can be attributed to the removal of lignin and waxy substances from the fiber by chemical treatment, which was confirmed by SEM. The obtained results indicate that composites reinforced with three layers of surface modified Luffa fibers showed overall improvement in static and dynamic mechanical behaviours

Ridge gourd/phenolic and glass/ridge gourd/phenolic hybrid composites were prepared using resol resin PF-108 as the matrix and the bilayered vegetable fabric ridge gourd as the reinforcement without and with alkali treatment and glass fabric as a co-reinforcement. The natural bilayer fabric of ridge gourd vegetable belonging to the Cucurbitaceae family was treated with 2% aqueous NaOH solution. The flexural strength and modulus of untreated and alkali treated ridge gourd fabric reinforced resol type (PF-108) composites and glass, ridge gourd fabric reinforced resol type (PF-108) hybrid composites in the absence and presence of two coupling agents were also determined.
