“…and their various applications. [27][28][29][30][31] However, there is no report on the effect of high-frequency microwave radiation treatment on the properties of plantain (Musa paradisiaca) fibre. This work is aimed at evaluating the effect of the physical modification on plantain fibre surface by applying microwave radiation treatments on the fibres.…”

“…The sampled raw plantain fibre was found to have a higher tensile strength of 2084.0Mpa compared to that analysed by Imoisili et al [1] and Ihueze et al [25] who obtained a fibre sample with Tensile strength of 489.5MPa and 536.2Mpa, respectively. However, Imoisili et al [1] observed an appreciable increase in tensile strength for alkaline concentrations up to 3%. This variation in optimal concentration for alkaline treatment may be due to difference in treatment process.…”

Plantain stalks obtained from solid waste stream of Ganmo market in Ilorin was used in this study. Natural fibres extraction from waste plantain stalk was achieved using biological retting methods. The natural fibre was rented from the waste stalk after 24 days of soaking in water. The extracted fibres were exposed to 2, 4 and 6% alkali solution (NaOH) treatment for two hours, washed and dried in the oven for 7 hours. Elemental analysis of raw plantain fibres showed the presence of elements like Indium, Potassium, Silicon and Calcium among others. Tensile strength analysis of the fibres, for single fibre strands showed that the 2% treated fibre showed distinctly promising potential with the highest tensile characteristics of young modulus, stress at break and force at peak of 52864.366N/mm 2 , 5398.536N/mm 2 and 2.650N, respectively. Evaluation of the chemical composition of plantain by FTIR spectroscopy indicated that treatment of natural fibres using NaOH beyond 2% have a negative impact on the plantain fibre properties. Through alkali exposure, the fibre configuration presents small variations in composition. It is consequently apparent that alkali treatment with concentration of less than 2% NaOH is sufficient to remove hemicelluloses and to obtain the optimum tensile effect.

“…It is therefore important to assess the extent of variation of elastic properties in plantain fiberreinforced polyester composites to guard against out of plane failure during structural applications. Unfortunately most studies involving plantain fiber-reinforced composites has dwelt on assessment of tensile, flexural and hardness properties [32], optimization of hardness strengths [33], effect of water and organic extractives removal [34], effects of fiber extraction techniques [35], optimization of flexural strength [36], compressive and impact strength evaluation [37][38][39], effect of high-frequency microwave radiation [40], effect of chemical treatment on the morphology [41], implications of interfacial energetics on mechanical strength [42]. Although Ihueze, Okafor and Okoye [43] has reported the longitudinal (1) and transverse (2) properties of plantain fiber-reinforced composites in Figure 1, there is still need to establish the essential elastic constants at directions other than the material axis directions 1-2.…”

Plantain fiber-reinforced composite materials have demonstrated significant properties that are applicable in structural design and development. However, two major concerns arise in relation to the obvious material anisotropy and challenges imposed by structural discontinuity encountered as need for use of fasteners arises. The study assesses the extent of variation of elastic properties (E x , E y , G xy , v xy , v yx , m x , m y) with fiber orientation using MATLAB functions while considering the extent of variation of the tangential stresses around an idealized functional hole edge. The tensile strength of 410.15 and 288.1 MPa was recorded at 0°fiber orientation angle, while 37.3397 and 33.133 MPa were obtained at fiber orientation angle of 90°for Plantain Empty Fruit Bunch Fiber Composite (PEFBFC) and Plantain Pseudo Stem Fiber Composite (PPSFC), respectively. The tangential stress distribution at hole edge indicated maximum stress value of 119.15 and 100.587 MPa at angular position ø = 90°for PEFBFC and PPSFC, respectively. Judging from various failure indices considered, failure will be initiated at ø = 70°for PEFBFC with stress concentration factor of 2.53 and ø = 65°for PPSFC with stress concentration factor of 2.13, which are less than the stress concentration around the peak stress when angular position is 90°. Both PEFBFC and PPSFC showed similar trends in response to the design scenario considered.
