Abstract

Suji leaves are one of the new materials that can form natural fibers. Suji leaf fiber is fiber obtained from suji leaves. Suji leaf fiber is one of the new materials that can be made into composite materials. The aim of this study was to determine the effect of immersing leaf fiber on liquid smoke and NaOH with fiber volume fractions of 15%, 20% and 25%, angular orientation (0°) and soaking times of 1 hour, 2 hours and 3 hours. Making composites using the hand-lay up method. Sampling using the full factorial method. The highest bending test result was in immersion of liquid smoke of 48.23 MPa at 25% fiber percentage with 1 hour immersion time. This means that the longer the soaking process of suji leaves with liquid smoke will decrease the flexural strength. The highest flexural test result was in NaOH immersion of 40.6 MPa at 20% fiber percentage with 3 hours of immersion time. This means that the longer the soaking process with NaOH will increase the flexural strength. Based on the BSAPI standard from the results of the bending test, the results obtained in this study cannot be used for making wall climbing panels because they do not meet the requirements, namely 112.8 Mpa, but for the manufacture of other materials such as car dashboards which have a type of High Impact ABS plastic material. 37-76 MPa.

Abstract

Synthetic fiber composite materials such as glass fiber, aramid and carbon fiber have good mechanical properties, but cause environmental pollution because they cannot be recycled. Because of this, many researchers are making composites with natural fibers. The advantages of natural fibers include: lower price, easy processing, reduced CO2 emissions, and specific strength meets application requirements. Composites are materials composed of a mixture of more than two different main elements. Composites have the advantages of light weight, higher strength, and corrosion resistance. This study applies the full factorial design method, which will look at the effect of the composite ratio (volume fraction and between fiber layers) on tensile strength. The purpose of this research is to determine the effect of variations in volume fraction and fiber layers of kepok banana stems on tensile strength. So that it can be used as an alternative material for making SNI helmets. This study used variations in volume fractions of 10%, 15%, and 20% and variations in fiber layers of 3, 4, and 5 kepok banana stems. Liquid smoke soaking time was 60 minutes. The average value of the maximum tensile test in the 4th layer, 10% volume fraction of fiber with a value of 42.76 Mpa and the minimum average value in the 3rd layer using 10% volume fraction of fiber with a value of 30.06 Mpa.

Abstract

Wood as the main raw material in making furniture causes the need for wood to increase while in its processing almost 30% of wood is wasted into waste just like that. In overcoming these problems, it is necessary to conduct research for the utilization of waste used for wood processing. Limited equipment in the manufacturing process becomes an obstacle to be one of the causes in the development of particle board products into a household industry. This research tried to make particle board with simple tools. This study used several parameters, namely 80:20, 70:30, 60:40, d and pressures of 7kg, 5kg, 3kg. The test results obtained the physical properties of wood dust composites with the Pva matrix, the lowest value was obtained at a variation of 80:20 pressure 7kg of 17.528% and the highest value at a variation of 60:40 pressure 7kg 117.237%. That the use of more matrices can inhibit water absorption is evidenced by micro photos at the 80:20 variation where the audience is no more than 25%. In the 60:40 variation, the use of more powder causes the glue bonding in this variation not to cover the powder as a whole like the 80:20 variation. Therefore, absorption at 60:40 is greater than at 80:20.

Abstract

During this time animal fibers were often used only for textile products, from the mechanical properties of the Tarantula Web that were already known, the idea arose to utilize the Web Tarantula as a composite reinforcement. Composites will not form if they only use reinforcement, it is necessary to have a mixture of matrices so that the composite can blend perfectly. This study will use a Hollow Glass Microsphere (HGM) & Epoxy matrix. The printing process is carried out in layers, the first layer pours the homogeneous half of HGM-Epoxy on the mold until it covers the base of the mold, then assembles the weighed web into the mold, and finally pours back the remaining HGM-Epoxy until it fills the mold. The tested specimen data was then processed using Microsoft Excel to determine the effect of volume fraction on the impact strength of the Web Tarantula composite with HGM-Epoxy homogeneous matrix. The conclusion in this study is, Web Tarantula fillers 10%, 20%, and 30% do not greatly affect the homogeneous mechanical strength of HGM-Epoxy 20%/80% and 30%/70%, from six specimens with different volume fractions, after impact testing using the Charpy impact method, the five composites have the same value, only one specimen with Web 30%, HGM 30%, and Epoxy 70% has slightly different values. It can be concluded that the volume fraction of Web Tarantula, Homogeneous HGM-Epoxy does not add impact strength to the specimen made.

Abstract

Wood is the main substance commonly used in the particle board manufacturing industry. However, the rate of forest destruction that continues to occur makes the availability of wood decrease. Alternative materials to replace wood are needed. The salak frond, the object of this study, is a non-wood material that can manufacture particle board. This study used the full factorial method to see the effect of impact testing by comparing the use of polyester matrix and salak frond powder in particle board specimens. The parameters in this study used variations in oven temperatures of 800, 1000, and 1200 degrees Celsius for 15 minutes and volume ratios between salak frond powder and polyester matrix 80:20, 70:30, and 60:40. From the test results, the highest mechanical properties of impact strength were obtained at a ratio of 70:30 with a temperature variation of 1000 and an average of 15.80 kJ/m2. The lowest value is found in a ratio of 60:40 with a temperature variation of 800 and an average of 6.65 kJ/m2. The test results of this study have exceeded the standard impact strength of particle board on the market, which is 3.201 kJ/m2
