[96 ] 2 Bamboo Moisture absorption An increase in moisture resulted in decreased interfacial shear strength. [97 ] 3 Palmyra Length and weight fraction Better mechanical properties were obtained with a length of 55 mm and a weight of 55%. [98 ] 4 Jute Water absorption An increase in water absorption resulted in poor flexural and compressive properties. [99 ] 5 Banana/sisal Length and weight Up to 50% by weight, mechanical properties increased and water absorption decreased. [100 ] 6 Banana/sisal Weight fraction The highest mechanical properties were obtained at 0.4%. [101 ] 7 Chopped snake grass Volume fraction Improved mechanical properties when the volume fraction increases. [80 ] 8 Abaca Fibre loading The mechanical properties showed an increasing tendency up to 40 wt.% of fibre loading. [102 ] 9 Banana/sisal Microfibrillar angle (MFA) High tensile characteristics are seen in fibres with high cellulose content and a low MFA content.

[106 ] 13 Luffa cylindrica Fibre content Improved mechanical properties at 40% fibre content. [107 ] 14 Oil palm Aging and wear behavior The wear test was carried out in dry conditions, and it was discovered that the composites immersed in engine oil and diesel performed better than the others. [108 ] 15 Lantana camara Load and fibre content (1) The proportional wear loss increased in direct proportion to the increase in normal load (2) The optimum wear resistance property was obtained at a fibre content of 40% [109 ] 16 Agave Fibre length (3, 5, and 7 mm) 3 mm agave fibre reinforcement that has been alkali-treated had better mechanical properties. [110 ] 17 Sansevieria cylindrica Fibre length and weight The mechanical characteristics of composites were optimal at 30 mm fibre length and then deteriorated beyond that. [111 ] 18 Vakka Volume fraction Tensile characteristics improved as the percentage of vakka fibre in the composite increased.
