No. Fibre Matrix Composites Applied treatment method Resultant properties Ref.
1. Abaca fibre reinforced composites Alkali treatment with 5 wt.% NaOH Increase in tensile strength of ~8% and interfacial shear strength of 32% [45]
2. Coir-fibre reinforced polymer composites 5wt.% NaOH alkali treatment at 20°C for 30 minutes Increase in tensile strength and flexural strength of 17.8% and 16.7%, respectively [46]
3. Benzoxazine resin reinforced with alfa fibres Alkali treatment with 5wt.% NaOH for 5 hours Enhancement of microhardness, flexural strength, and modulus by 29, 37 and 10%, respectively. [47]
4. Oil palm/bagasse fibre reinforced phenolic hybrid composites 2% v/v silane treatment and 4% v/v hydrogen peroxide Increase in tensile strength and flexural strength of ~56 and 120%, respectively [48]
5. Acacia tortilis fibre reinforced natural composite Alkali treatment with 10 wt.% NaOH Enhancement of tensile strength by 27.5%. [49]
6. Flax/banana/industrial waste tea leaf fibre reinforced hybrid polymer composite 5 wt.% NaOH treatment for 12 hours at 27°C. Tensile and flexural strength were enhanced by ~7% and ~5% respectively. [50]
7. Mutingia Calabura bark fibre reinforced green-epoxy composite 2-hour alkali treatment with 5% NaOH.2% silane treatment for 2 hours. Crystallinity index enhancement of 41.01% with NaOH and 14.86% by silane treatment.Tensile strength improvement of 37.75% and 28.92% with NaOH and by silane treatment, respectively.Thermal stability improvement of 14.15% and 4.81% for NaOH and silane treatment, respectively [51]
8. Coir and oil palm empty fruit bunch Acetylation with a mixture of toluene, methanol, and acetone (4:1:1 volume ratio) for 5 hours at 100°C Increase of tensile strength by 8% and 10.8% for coir and oil palm fruit bunch respectively [52]
