“…Overall, however, the compressive strength is found to be higher when alkali treated ridge gourd fabric was used. This is as expected, since alkali treated fabric becomes more crystalline by the removal of a considerable amount of amorphous hemi-cellulose and lignin [10]. In order to improve the compressive properties of these composites, an attempt was made by the authors to hybridize them with glass mat.…”

“…Further, with the use of coupling agents, matrix skin formation is observed on the fiber surface, indicating strong bonding between the fibers and the matrix (Figures 5e and 5f). Varada Rajulu et al [10] has already showed that with alkali treatment, the surface of the fibers in ridge gourd fabric became rough. This may be the reason for better interfacial bonding on alkali treatment.…”

Ridge gourd/phenolic and ridge gourd/phenolic/glass hybrid composites were prepared using resol resin PF-108 as the matrix, the twin layered vegetable fabric ridge gourd (without and with alkali treatment) as the reinforcement and glass fabric as a co-reinforcement. The compressive strength, the modulus of untreated and alkali treated ridge gourd fabric reinforced phenolic composites and the ridge gourd and glass fabric reinforced phenolic hybrid composites in the absence and presence of two coupling agents were also determined. The interfacial bonding between the components of these composites was examined by scanning electron microscopy.

A naturally occurring fabric belonging to the species Hardwikia binata was extracted from the sheath of stem, bark, and branches of the tree. The fabric specimens were treated with sodium hydroxide and poly (vinyl alcohol). The morphology of the fabric specimens before and after NaOH treatment was studied using scanning electron microscopy technique. Ligno-cellulosic properties of fabric were analyzed by XRD, FTIR, and thermo gravimetric methods before and after NaOH treatment. Tensile strength and percentage of elongation at break of the fabric were also studied by using a universal testing machine (model AGS-10kNG). The results showed that the poly (vinyl alcohol)-treated fabric specimens showed higher tensile strength than sodium hydroxide-treated fabric specimens. The Binata fabric has good thermal resistance and was also found to increase by alkali treatment. The FTIR method indicates lowering the hemi cellulose and lignin content by alkali treatment in the fabric. Further, the X-ray diffraction studies revealed an increase in crystallinity of the fabric by alkali treatment.

ABSTRACT:The uniaxial natural fabric Prosopis chilensis was treated with NaOH (alkali), poly (vinyl alcohol) (PVA), and polycarbonate (PC) solutions. The Prosopis chilensis fabric belongs to Leguminosae family. The properties of lignocellulosic fabric and the effect of sodium hydroxide (NaOH) treatment were evaluated using thermal analysis by means of thermogravimetric and differential scanning calorimetry analysis, Autonated total reflection-fourier transform infrared spectroscopy, X-ray diffraction (XRD), and field emission scanning electron microscopy. Tensile properties of the untreated and fabric treated with NaOH, PVA, and PC were also studied to assess their performance. The fabric has good thermal resistance on alkali treatment. The FTIR method indicates lowering the hemi cellulose and lignin content by alkali treatment. Further, the XRD studies reveal that crystallinity of the fabric increases on alkali treatment. Tensile properties of the fabric were enhanced on treatments with NaOH, PVA, and PC treatments.
