Abstract

The design concept is used for the development of natural plant fiber extractors as raw materials for making natural fiber composites. The extractor is a tool used to extract natural plant fibers which are expected to produce natural fibers as raw materials for making natural fiber composites. In the previous tool, there are still several shortcomings that can be redeveloped, both for the sake of the tool itself and in terms of the fiber produced. In this journal, it is focused on making design concepts before the development of the extractor tool, including identifying problems in previous tools, determining the functional structure, finding solutions to existing problems, determining development specifications on the tool and also evaluating from the technical and economic side. In the process of this design concept, There are several things that are highlighted in the previous tools to be developed, including the mobility of the tool, the quality and quantity of fiber produced, production time and safety aspects and also environmentally friendly. Thus, in the end, all of it will be narrowed down to the choice of specifications needed to support this with the consideration of the objective tree.

Abstract

This study developed an environmentally friendly composite material for use in roller weights of Continuously Variable Transmission (CVT) systems in motorcycles. The composite, made from teak wood powder (Tectona grandis L.F.) and epoxy resin, was formulated as an alternative to conventional PTFE (Polytetrafluoroethylene), which is less environmentally sustainable. The composite was fabricated using the hot-press method, with variations in the teak-resin composition ratios (60:40, 70:30, and 80:20) and hot-press temperatures (160°C, 170°C, and 180°C). The results showed that the composite with a 60:40 composition at 180°C and 20 bar pressure achieved the highest tensile strength of 25 MPa, exceeding that of conventional roller weight material (23 MPa). Tensile testing was conducted in accordance with ASTM D3039 standards. In addition to its superior mechanical performance, the material also utilizes biomass waste and has the potential to reduce production costs. These findings demonstrate that teak wood powder composite is a viable candidate for strong, durable roller weight applications and supports the development of more sustainable automotive components.

Abstract

This study investigates the mechanical properties of composites reinforced with banana frond waste fibers compared to those reinforced with traditional glass fibers. The increasing environmental concerns and the need for sustainable materials have driven the exploration of natural fibers as viable alternatives to synthetic fibers in composite materials. Banana frond waste, a byproduct of banana cultivation, offers a renewable and biodegradable option for composite reinforcement.Composites were fabricated using both banana frond waste fibers and glass fibers, and their mechanical properties, including tensile strength, bending strength, and impact resistance, were evaluated and compared. The results indicated that while glass fiber composites exhibited higher overall mechanical performance, banana frond waste fiber composites showed competitive properties, particularly in terms of impact resistance and specific strength. The natural fibers demonstrated adequate bonding with the polymer matrix, contributing to the composite's overall integrity.Moreover, the use of banana frond waste fibers significantly reduced the composite's environmental footprint, making them a promising alternative for various applications where moderate mechanical performance is sufficient. The study highlights the potential of banana frond waste fibers as a sustainable reinforcement material, encouraging further research and development in this area to optimize their mechanical properties and broaden their application scope.
