Strength Analysis and Variation of Elastic Properties in Plantain Fiber/Polyester Composites for Structural Applications

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

Analysis and Application of Natural Fiber Reinforced Polyester Composites to Automobile Fender

In Nigeria, little attention has been given to the analyses and applications of natural fibers for automobile body parts production. Hence in this work, an attempt is made to evaluate the compressive and impact strength of plantain fiber reinforced polyester composites (PFRC) and to develop an automobile fender using plantain fiber reinforced polyester composites. The PFRC automobile fender was constructed using the hand lay-up technique. The method adopted to achieve the PFRC fender involved fiber extraction, fiber surface treatment, laminates development for impact and compressive test experiment and the development of automobile fender. Experimental investigations for compressive and impact tests were carried out on the laminates which were prepared according to the ASTM D256 and ASTM D1621 standards, respectively. The impact strength result of the PFRC with volume fraction 0.25 and 0.3 was 12.22J/m2 and 12.83J/m2, respectively. The compressive strength, shear stress and resultant stress results of PFRC laminates with volume fraction 0.25 and 0.3 were 62.52MPa, 31.26MPa, 69.99MPa and 68.98MPa, 34.49MPa, 77.12MPa, respectively. From the results, it was observed that the strength of the plantain fiber reinforced polyester composites depend on the fiber volume fraction. The constructed automobile fender was simulated in a Solidworks software environment and was found that the edges, especially the circular part of the automobile fender have high stress concentrations. The production of the automobile fender using PFRC was done at low cost

HYGROTHERMAL RESPONSE OF PLANT FIBRE REINFORCED COMPOSITES

ABSTRACT The effect of soaking time and temperature response for coconut and raffia fibre reinforced composite on their mechanical properties have been studied. Tensile and compression test for treated and untreated were performed using a universal testing machine (Monsanto Tensometer). The conditioned samples in each case show better tensile and compressive strength compared to the untreated samples. Raffia fibre reinforced polyester showed a better mechanical and moisture absorption properties at various operating temperature in the study
