PROJECT PAPERStab-Resistant and Ballistic Vest made from Coconut FiberCATEGORY : ENVIRONMENT-COMPOSITE TECHNOLOGYRESEARCHERSStudent 1Name:Muhammad Iqbal FauziStudent 2Name:Aristo Kevin Ardyaneira PratamaSupervisorName:Drs. Agus Priyatno, M.PdState Senior High School 3 SemarangCentral Java, IndonesiaABSTRACTStab-Resistant and Ballistic Vest made from Coconut FiberIn the twentieth century, ballistic vest and stab-resistant vest which usually used made from para-aramid synthetic fiber which patented in the name of Kevlar by DuPont. Although kevlar has some advantages. It is cost very much depend on the world market price. This is because the use of sulphate acid in production is rather difficult. This limitations make usual civil person hard to own stab-resistant and ballistic vest to protect himself. Furthermore, kevlar is a synthetic chemical elements that was non-biodegradable. As the consequences, expired kevlar must be recycling in order to keep the environment safe. Based on the literature study, its known that s-glass fiber cloth is cheaper, higher tensile strength, higher tenacity, higher break elongation, higher decompression temperature, and more compatible to the resin than kevlar. Also, based on the study, its known that coconut fiber has the highest break elongation among the other natural fiber which make them very flexible. It is also very easy to find in the tropical countries than the other natural fiber. Therefore, researcher combine them to make semi-organic composite material that cheaper, easier to be made, and more environmentally friendly to be used as alternative stab-resistant and ballistic vest. The purpose of this research are : (1) to know the ways to make stab-resistant and ballistic vest made from coconut fiber, (2) to know the cost of production to make stab-resistant and ballistic vest made from coconut fiber, (3) to know whether stab-resistant and ballistic vest made from coconut fiber can resist level IIA bullet impact until it meets certain safety limitation based on NIJ standard (4) to know whether stab-resistant and ballistic vest made from coconut fiber can resist level II sharp point impact until it meets certain safety limitation based on NIJ standard. The price analysis, ballistic tests, and stab tests show that stab-resistant and ballistic vest made from coconut fiber can resist level IIA bullet impact and level II sharp point impact with minimum thickness 1,35 cm, minimum mass 2,916 kg, and maximum production cost Rp. 857.126,65.Keywords: s-glass fiber cloth, coconut fiber, para-aramid fiber, resin, NIJ standardPREFACEThe first and foremost, researcher wish to express greatest gratitude to The God Almighty for the blessing, grace, love, and strength leading to the completion of our project entitled Stab-Resistant and Ballistic Vest made from Coconut Fiber to follow The 2nd International Science Project Olympiad (ISPrO).ISPrO is an event intends to seek students which have talent and skills in composing scientific project. In this opportunity, the researchers want to show their ideas about the use of coconut fiber as the material for making stab-resistant and ballistic vest.In conducting this research. Researcher find several obstacles that must be faced one of which are the lack of time, information, and place to test the performance of stab-resistant and ballistc vest made from coconut fiber. But then, those obstacles can be solved in time due to the guidance and assistance of various parties. Therefore, researcher would like to express our gratitude to these following people:Drs. H. Bambang Nianto Mulyo, M.Ed, as the principal of State Senior High School 3 Semarang who has permitted researcher to join this event.Drs. Agus Prayitno, M.Pd, as the first advisor who has given researcher his guidance and advise, and also has corrected this scientific paper.Sri Mulyani, M.Kom, as the second advisor who has corrected this paper.Drs. Markus Sutiono, as composite technician who has gave us some suggestions about glass fiber and resin mixture.Drs. Kartono, as Kasubbid Balmetfor of Forensic Laboratory Police Academy and Manager of PERBAKIN who have helped us test the performance of ballistic vest made from coconut fiber.Mr. Dwi Setyambudi from Battalyon Infantry Yonif 400/Raider who has helped us test the performance of ballistic vest made from coconut fiber. Mr. Suroso, as the owner of Mr. Suroso’s Workshop who has borrow us pressor tools to press the panel. Our parents, who have helped researcher and supported researcher in doing this project.Pasiad institute, who have recommended researcher to join this international eventAll people who have contributed for the finishing of this project.Researcher hope that this research will give benefits to the society. Researcher realized that the results of this research are still imperfect, so that researcher need criticism from the readers in order to make us better in our future research.Semarang, 11th January 2014ResearcherTABLE OF CONTENTTITLEiABSTRACTiiPREFACEiiiTABLE OF CONTENTvLIST OF PICTURE AND PHOTO…………………………………………………………viiiLIST OF ILLUSTRATIONixLIST OF TABLExCHAPTER I : INTRODUCTION1Background Issue1Problem Limitations1Problem Statements2Research Purposes2The Benefit of Research2CHAPTER II : LITERATURE STUDY3 2.1.Ballistic Vest3 2.2.Coconut Fiber42.2.1.The Kind of Coconut Fiber42.2.1.1.Mature Brown Coconut Fiber42.2.1.2.White Coconut Fiber52.2.2.Mechanical Properties of Coconut Fiber52.2.3.Chemical Treatment of Coconut Fiber5 2.posite Material6 2.4.Fiberglass62.4.1.The Definition of Fiberglass62.4.2.The History of Fiberglass62.4.3.Mechanical Properties of Fiberglass7 2.5.Jeans10 2.6.Kinetic Energy10 2.7.Stab Resistance Vest102.7.1.Edged Blade Class112.7.2.Spike Class112.7.3.Stab-Resistant Panel Test11 2.8.Synthetic Resin112.8.1.Thermoplastic Resin122.8.2.Thermosetting Resin122.8.2.1.Polyester Resin122.8.2.2.Vinylester Resin132.8.2.3.Epoxy Resin13 2.9.Hypotheses14CHAPTER III : RESEARCH METHODOLOGY16 3.1.Research Methods16 3.2.Research Procedures16 3.3.Research Time and Place17 3.4.Ballistic Test Methods19 3.5.Stab Test Methods19 3.6.Instrument and Materials19 3.7.The Ways of Making203.7.1.First Panel Design with Polyester Resin203.7.1.1.S-Glass Fiber Cloth Arrangement203.7.1.2.Coconut Fiber Preparation and Arrangement203.7.2.Second Panel Design with Epoxy Resin213.7.2.1.S-Glass Fiber Cloth Arrangement213.7.2.2.Coconut Fiber Arrangement213.7.3.Third Panel Design with Epoxy Resin223.7.3.1.S-Glass Fiber Cloth and Jeans Sheet Arrangement233.7.3.2.Coconut Fiber Arrangement233.7.4.Fourth Panel Design with Epoxy Resin243.7.4.1.S-Glass, E-Glass Fiber Cloth, and Jeans Sheet Arrangement243.7.4.2.Coconut Fiber Arrangement24 3.8.Reporting Methods25CHAPTER IV : RESULT AND DISCUSSION27 4.1.Panel Specimen274.1.1.The First Panel Specimen274.1.1.1.The First Panel Specimen Specification274.1.1.2.The First Panel Specimen Production Cost284.1.2.The Second Panel Specimen284.1.2.1.The Second Panel Specimen Specification284.1.2.2.The Second Panel Specimen Production Cost304.1.3.The Third Panel Specimen304.1.3.1.The Third Panel Specimen Specification304.1.3.2.The Third Panel Specimen Production Cost324.1.4.The Fourth Panel Specimen324.1.4.1.The Fourth Panel Specimen Specification324.1.4.2.The Fourth Panel Specimen Production Cost34 4.2.Price Comparison between Stab-Ballistic Vest made from Coconut Fiber and Ballistic Vest made from Para-Aramid35 4.3.Ballistic Test Result35 4.4.Stab Test Result36 4.5.Discussions36CHAPTER V : CONCLUSIONS AND SUGGESTIONS38 5.1.Conclusions38 5.2.Suggestions38REFERENCES39ATTACHMENT42LIST OF PICTURE AND PHOTOPicture 2.1. : Blue jeans texture…………………………………………………………...10Picture 2.2. : Polyester resin chemical structure…………………………………………..12Picture 2.3. : Vinylester resin chemical structure…………………………………………13Photo 4.1. : The first panel specimen…………………………………………………….27Photo 4.2. : The second panel specimen…………………………………………………29Photo 4.3. : The second panel layer photo……………………………………………….29Photo 4.4. : The third panel specimen……………………………………………………31Photo 4.5. : The third panel layer photo…………………………………………………32Photo 4.6. : The fourth panel specimen………………………………………………….33Photo 4.7. : The fourth panel layer photo………………………………………………..34Photo 4.8. : M1911 Pistol and Revolver Colt Police Positive Special…………………..35Photo 1 : E-glass fiber cloth and S-glass fiber cloth…………………………………..42Photo 2: Coconut Fiber……………………………………………………………….42Photo 3: Polyester Resin & Catalyst and Epoxy Resin & Hardener…………………42Photo 4: Epoxy Thinner………………………………………………………………43Photo 5: Cutting Fiber Cloth and measuring epoxy resin and hardener ratio………..43Photo 6: Measuring thinner ratio and preparing coconut fiber………………………43Photo 7: Pressing the panel with workshop pressure tool…………………………....44Photo 8: Testing the panel with Steyr LG-110 FT gas air gun ;
