Production of A Safety Helmet Using Palm Kernel Fiber And Shell Particulates
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 2
Abstract
Palm Kernel Fiber (PKF) with Palm Kernel Shell (PKS) particulates as filler were used as reinforcement in polymer matrix composite to investigate their suitability for the production of a safety helmet. The Palm Kernel Fiber (PKF) was initially used as the reinforcement while epoxy resin (Bisphenol-A-glycidyl) served as the matrix. Six specimen were produced having 2.5%, 5%, 7.5%, 10%, 12.5% and 15% PKF content in the composite and their mechanical properties (Tensile strength, Impact strength, Flexural strength and Hardness strength) were evaluated. The specimen having the optimum desirable mechanical properties was adopted for hybridization with the PKS as filler. Specimen D (10% PKF) with the highest impact strength of 6.62 J/mm2 , hardness of 6.9 HRF, tensile strength of 26.75 N/mm2 and flexural strength of 31.02 N/mm2 was selected and reproduced with PKS particulates as filler. The PKF and PKS were mixed in the ratio of 1% PKS - 9% PKF, 2% PKS – 8% PKF, 3% PKS – 7% PKF, 4% PKS – 6% PKF, 5% PKS – 5% PKF and 6% PKS – 4% PKF. All the mechanical tests (Impact, hardness, tensile and flexural strength) evaluated for the hybrid samples. Specimen D6 (6% PKF – 4% PKS) offered the most acceptable combination of mechanical properties; impact strength of 7.27 J/mm2 , hardness of 6.7 HRF, tensile strength of 21.55 N/mm2 and flexural strength of 34.61 N/mm2 . Since impact is the most critical property in this research, and specimen D6 offered the highest, it was adopted for the production of the sample safety helmet.
