“…[30] When fiber is treated with NaOH solution, the amount of hemicellulose and lignin decreases, causing fiber fibrillation (breaking down of fiber bundles), and the interfacial surface area for contact between fiber and matrix increases. [31,32] After 5% silane treatment, tensile and flexural strength increases in comparison to untreated fiber composite with values 23.03 and 43.54 MPa, respectively. This is because the silane coupling agents make a layer on the surface of the fiber, and their adherence through the matrix increases.…”

Currently, natural fiber composites are used in many applications (industrial, automotive, and construction) where fire resistance is a critical factor. The main objective of this research work is to investigate the thermal degradation and fire performance of raw and treated fiber composites developed using hand layup with different fiber loadings of 5, 10, 15, and 20 wt%. Alkali treatment (5%, wt/vol) and silane treatment (5%, wt/vol) were used to improve the thermal stability and compatibility of hemp fiber with polymer matrix. The developed composites were characterized for thermal (thermogravimetric analysis), chemical (Fourier transform spectroscopy), morphological (scanning electron microscopy and X-ray diffraction), and mechanical behavior. Further, the flammability behavior of the developed composites was investigated using vertical cum horizontal flammability test apparatus and limiting oxygen index (LOI) tester. The results of mechanical characterization reveal that alkali treated fiber composites (20% loading) have the highest tensile strength (24.4 MPa) and flexural strength (46.1 MPa). Composite reinforced with silane-treated fibers have shown excellent flame retardancy with the lowest horizontal burning rate (16.11 mm/min) and higher LOI (23.5%). Scanning electron microscopy confirms the better fiber-matrix compatibility of silane-treated fiber with epoxy.

“…[13,14] The need for a biodegradable alternative material for engineering structures has prompted researchers to look at the utilization of natural resources as a part of advanced materials with the objective of reducing the use of steel, plastics in different structures. [15,16] A. Cantala is a leafy fiber plant from the family of Asparagaceae which contains almost 257-341 species of Agavaceae. [17,18] Mexico is the motherland of A. Cantala and slowly it started evolving around the Philippines, India, and Indonesia.…”

The use of lignocellulosic fibers into polymer matrices gained attention of the researchers and brought substantial research. The main objective of this research work is to determine the thermal characteristics and hygrothermal aging of untreated and surface modified Agave Cantala plant fiber-reinforced polylactide composites. Cellulosic fibers were extracted from the fleshy leaves of the plant by water and mechanical retting processes. The extracted fibers were treated with trimethoxy methyl silane and fabrication of the composites was done using matched die molding method. These composites are characterized by thermo-gravimetry analysis, Fourier transform infrared spectroscopy, X-ray diffraction study, hygrothermal aging, energy dispersive X-ray spectroscopy and field emission scanning electron microscopy analysis. The results showed the trimethoxy methyl silane treated A. Cantala treated fiber reinforced composites exhibiting better thermal, hygrothermal, and morphological behavior.
