“…While natural fiber composites have several advantages over synthetic fibers, namely high specific strength, environmentally friendly, cheaper and not harmful to health [9] [10]. Then it is supported by the potential of Indonesia's plant wealth which is very abundant in natural fibers such as coconut, banana, pandanus and Boehmeria Nivea plants [11].…”

Composites are a combination of two or more different materials with different mechanical properties. The purpose of this research was to determine the effect of the angle orientation of the Boehmeria Nivea fiber-reinforced composite woven on the physical and mechanical properties. Boehmeria Nivea fiber is soaked in an alkaline solution and made into ropes with a diameter of 2-3 mm and then woven with angle orientations of 0o/15o, 0o/30o, 0o/45o and 0o/90o. The composite manufacturing process uses the press molding method. The tests in this study consisted of a tensile test with the ASTM D3039 standard, a flexural test with the ISO 178 standard and a density test with the ASTM C271 standard. Tensile test results show that the highest tensile strength occurs at 0°/15° webbing angle orientation, which is 13.77 Mpa. While the highest bending test results occur at the orientation of the 0°/15° webbing angle, which is 60.52 MPa. Tensile and flexural strength increases with smaller webbing angle orientation.

“…Natural fibers are also believed to have good mechanical properties for use as composite materials (Asroni & Nurkholis, 2016). Plants that can be used as composite fibers are plants that contain a lot of cellulose, for example, hemp plants [14].…”

Research on hemp fiber composites with epoxy resin matrix and lead acetate as an alternative material for X-ray radiation shielding has been conducted to determine the optimal composition of radiation shielding samples made from hemp fiber, epoxy resin, and lead acetate. The method used to make composite samples with six different designs, namely using a ratio of 4 gams, eight gams, and 12 gams of hemp fiber to 80 gams and 160 gams of resin. The lead acetate used in each composition is 2.5 gams. This study carried out three measurement processes: density, attenuation, and absorption. Density measurements were carried out by measuring the volume and mass of the sample. In contrast, attenuation and absorption measurements were carried out using a mobile X-ray aircraft with a Piranha multi-X-ray meter detector. In the three measures, the highest value was obtained in composition VI, namely with 12 gams of hemp fiber, 160 gams of epoxy resin, 80 gams of catalyst, and 2.5 gams of lead astate. The density value obtained was 1.120 g/cm3. The sample with this composition can absorb 71.22% (1.24580 cm-1) of radiation at 40 kV, absorb 66.91% (1.10621 cm-1) at 60 kV and 60.22% (0.92191 cm-1) of radiation absorbed at 81 kV voltage. Therefore, it can be concluded that the higher resin and hemp used, the more excellent density value obtained—the geater density of the sample, the geater value of attenuation and absorption.

Composites with natural fiber reinforcement have been widely used in various field. Natural fibers have the advantages of easy recycling, environmentally-friendly characters, renewable, non-toxic, inexpensive, high toughness, good insulation against heat and noise, and good thermal properties. The aim of this paper is compare natural fibers used as reinforcing material on composite with an epoxy matrix and the addition of carbon nanotubes (CNT). The natural fibers used are oil palm empty fruit bunches (OPEFB), bagasse, and hemp fiber. Alkalization treatment with NaOH was carried out on natural fibers to remove impurities on the fiber surface and activate hydroxyl groups. CNTs need to be functionalized to achieve the desired compatibility. Functionalization is carried out by the mild acid oxidation method using nitric acid and hydrogen peroxide. Silane coupling agent treatment is carried out on natural fibers and CNTs to improve compatibility with the matrix. The result of the bending strength test of OPEFB, bagasse, and hemp fiber was 509.94 MPa, 36.22 MPa, and 18.12, respectively, in addition to CNT 0.5% mass. The bending strength of OPEFB fiberismore significant than bagasse and hemp fiber, so it has the opportunity to be developed in the automotive industry.
