Influence of the Extraction Location on the Physical and Mechanical Properties of the Pseudo-Trunk Banana Fibers

Extraction and characterization of a novel tropical fibre Megaphrynium macrostachyum as a biosourced reinforcement for gypsum-based biocomposites

“…11,50 Under tensile stress, the MMB fibre exhibits a single domain of linear behaviour up to a strain of 2.6% with a tensile strength of 108 MPa and a Young's modulus of 3.2 GPa. This type of behaviour has already been observed in the soy 38 and banana 7 fibres. The behaviour of the MMB fibre is similar to that of the MMKW fibre, but differs from that of the MMK fibre, which has a non-linear initial deformation zone.…”

“…The density ρ of the fibres was estimated with equation (1) by a toluene immersion test (normalρt = 0.866 g.cm −3 ) using a pycnometer according to ASTM D 2320-98. 7 Before the tests, the fibres were cut into small 5 mm pieces and dried in an oven at 105°C for 24 h. 13 Each sample was immersed in toluene for about 2 h to remove air bubbles. 12 In this equation, m0, m1, m2 and m3 are the masses of the empty pycnometer, the pycnometer filled with toluene at room temperature, the pycnometer filled with fibres and the pycnometer filled with fibres and toluene at room temperature.…”

“…3,4 They are mainly composed of cellulose, non-cellulosic materials (hemicellulose, lignin and pectin) and extractives in small proportions. [5][6][7] The physical, thermal and mechanical properties of plant fibres depend on the proportion of these chemical constituents. Hydrogen bonding in the cellulosic structure contributes to improved mechanical properties, while hemicellulose is responsible for the hydrophilic character of the fibres and contributes to their biodegradation, and hinders their thermal resistance.…”

“…9 Many tropical fibres have been investigated over the last decade as alternative raw materials for the development of composites. These include fibres from the Neuropeltis acuminatas liana, 12 banana, 7 Ananas comosus leaf 13 and Triumpheta Pentadra stem. 14 However, other types of tropical fibres are commonly used in cottage industries to make items useful for daily life (baskets, blankets or ropes).…”
