The aim of the present work pointed out the introduction of natural alkalised alpha fibres as reinforcement in the preparation of partially biodegradable green insulation material composite. Thermal conductivity, mechanical properties and acoustical performances of composites were investigated as a function of fibre content. We found that 10% of alkali solution improve the hydrophobic character, mechanical and interfacial properties of the fibers. Composites made of alfa fibers-polyurethane resin has exhibited good mechanical and acoustical properties. At 20% of reinforcement the Young modulus and tensile stress increased by 48.14% and 74.12%, respectively.

“…The strong and broad absorption peak at the range of 3500 to 3300 cm -1 arises from the O-H stretching vibration of hydroxyl groups, and was found to decrease with increasing NaOH concentration. This result indicated that alkali treatment reduced the polarity and hydrophilicity of the SS fiber (Oushabi et al 2017). Similarly, intensity weakening of the absorbance peaks was observed for the 2918, 1635, 1383, and 1053 cm -1 peaks.…”

The application of wood-plastic composites is growing rapidly in the fields of corrosion and aging. The present study investigated the effect of alkalitreated (with NaOH concentrations of 0.5, 2.5, 4.5, and 6.5%) sorghum straw (SS) fiber on the wear resistance of polyvinyl chloride (PVC) composites under simulated seawater and acid rain conditions. The results showed that the wear resistance of the SS/PVC composites was noticeably improved by the addition of the alkali-treated SS fiber. SS fiber treated with 4.5% NaOH showed low polarity and hydrophilicity with high crystallinity and improved mechanical properties, which endowed the SS/PVC composites with high interfacial bonding and wear resistance. Exposure to simulated seawater and acid rain resulted in the deterioration of physical (including water repellency and hardness), mechanical, thermal, and wear-resistance properties of the composites; the wear mechanism of the SS/PVC composites after corrosion for 12 days was mainly abrasive wear.

“…Young's modulus and tensile strength alpha fibre/polypropylene composite were improved by 23% and 16% respectively after alkali treatment [7]. Some other researchers also found improvement in the properties of the bio composites after alkali treatment [8][9][10]. Tensile strength and tensile modulus of bamboo composite [11] and palmyra palm leaf stalk fibre composites [12] were also improved by benzoyl chloride treatment.…”

In this work, woven jute fibres were subjected to ecofriendly and chemical treatments (alkali, benzoylation and sodium bicarbonate) and PLA coating in order to improve the adhesion with epoxy thereby improvement in the performances of their composites. Treated and coated jute fibres reinforced epoxy composites were prepared by hand lay-up technique keeping constant 30 wt% of fibres content in the each composite. Mechanical properties (i.e. tensile, flexural and impact) and dynamic mechanical properties (i.e. storage modulus, loss modulus, damping and glass transition temperature) of prepared composites were studied. The outcomes from the experimental results suggested that benzoyl chloride treated and PLA coated jute composite exhibited the best performance as compared to other all the composites. There were 21%, 40.6% and 27.5% improvement in tensile strength, flexural strength and impact strength respectively for this composite as compared to that of untreated jute fibre reinforced composites. Moreover, storage and loss modulus of jute composites were also significantly enhanced by treatment and coating. The present developed composites can be used for medium strength application in the field of automobile, building and construction and packaging.
