Indonesia has a large variety of natural fibers in abundance. Some of natural fibers become organic waste if not used for something needed by humans. One of the potential uses of natural fiber composite materials is to be used in automotive components. But before natural fiber composites are used in automotive components, it is necessary to examine first what are the requirements for mechanical properties or other properties required by the automotive components. Especially the automotive components which have been made from Polymers, like  dash board, Car interior walls, front and rear bumper and Car body, etc. Each of these automotive components has different function and condition, and that caused different mechanical properties needed. The purpose of this study is collecting the data from the literature, related to the properties needed for these automotive components. This study was conducted by studying the literature of research journals in the last 10 years. From the research journals, data on the requirements of mechanical properties for automotive components will be collected. Furthermore, the data of mechanical properties required for automotive components can be used as a reference to determine the reliability of automotive components made from composite

Mechanical And Tribological Characteristics

In the framework of green materials, in recent years, natural fiber composites attracted great attention of academia and industry. Their mechanical and tribological characteristics, such as high strength, elasticity, friction, and wear resistance, make them suitable for a wide range of industrial applications in which issues regarding a large amount of disposal are to be considered since their environmental friendliness gives them an advantage over conventional synthetic materials. Based on the recent and relevant investigations found in the scientific literature, an overview focused on the tribological characteristics of composite materials reinforced with different types of natural fibers is presented. The aim is to introduce the reader to the issues, exploring the actual knowledge of the friction and wear characteristics of the composites under the influence of different operating parameters, as well as the chemical treatment of fibers. The main experimental tribological techniques and the main used apparatus are also discussed, with the aim of highlighting the most appropriate future research directions to achieve a complete framework on the tribological behavior of many possible natural fiber composite materials.

Property Variation

Properties of composite materials are often predicted from properties of its component materials. In the case of green composites that are typically filled with natural fibers however, a large deviation from predictions is observed due to the large property variation in natural fibers. In this study, techniques have been developed to minimize the effect of the said variations, which included the determination of a fiber useful length and critical length, and the utilization of controlled chemical treatment to remove unwanted fiber components that interfere in fiber-matrix interfacial bonding. The abaca fiber was determined to have a diameter of 190 + 2 mm in about two-thirds of the fiber length in the middle section. A large variation in fiber diameter was observed at the root and tip sections such that the diameter could be as high as 200 mm at the root while the tip tapers to 110 to 165 mm. The useful length with constant diameter was determined to be about 2000 mm at the middle section. The critical length of this useful length was found to be 3.15 mm. The tensile strength was also determined to have an average of 970 MPa when measured at 15 mm gauge lengths but is found to decrease up to 796 MPa with increasing gauge lengths up to 35 mm. This superior tensile strength of abaca is also associated to the 2-3o microfibril misorientation from the axis of the fiber. Use of the fibers in composite as continuous and unidirectional filler at 5% loading to unsaturated polyester (tensile strength of 40 MPa) resulted to a tensile strength of 48 MPa. The tensile strength increased to 71 MPa when chemically treated continuous fiber was employed. Alkali treatment at relatively high temperature improved the surface morphology of the fiber, with waxes and lignin removed from the surface and activating the surface with hydroxyl functional groups, that essentially improved the wettability of the polymer to the fiber, and densified the fiber with the closure of its lumens.

Fiber Reinforced Polymer Composites

The applications of natural fiber composites have enormously increased due to the high availability, eco-friendly nature and practical applications of the composites. In this review different fiber combinations using natural fiber and synthetic fibers have been investigated and found with interesting results. The hybrid nature of fiber reinforcement adds to the mechanical properties of polymer-based composites. The hybridization using more than one fiber reduces the surface deformations in the polymer matrix and enhanced the bonding ability of polymer composites. The alkali treatment was the effective surface treatment process for improving the cellulosic nature with good crystalline nature, good bonding ability with the polymer matrix, this adds to the properties of polymer-based composites. The crystallinity index of 43-68 % were observed in surface treated natural fibers.

This research paper reports a study on thermal and sound insulation samples developed from sugarcane bagasse and bamboo charcoal for automotive industry applications. The sugarcane bagasse and bamboo charcoal fiber is a potential source of raw material that can be considered for thermal and sound insulation applications. Natural fibers are commonly used in diverse applications and one of the most important applications is sound absorption. Natural fiber hybrid composite currently is in greater demand in industries because of their advantages such as low cost, biodegradability, acceptable physical properties, and so on. Eco-friendly sound-absorbing composite materials have been developed using bamboo charcoal and sugarcane bagasse fibers. From these fibers five types of natural fiber green composite were developed using the compression bonding technique. The natural composite noise control performance contributes to its wider adoption as sound absorbers. The sound absorption coefficient was measured according to ASTM E 1050 by the Impedance tube method. The physical properties of natural fiber composites such as thickness, density, porosity, air permeability, and thermal conductivity were analyzed for all samples in accordance with ASTM Standard. The result exposed that natural fiber green composite were absorbing the sound resistance of more than 70% and the natural fibers composites provide the best acoustic absorption properties, these composite materials have adequate moisture resistance at high humidity conditions without affecting the insulation and acoustic properties.

Armor System

Natural-fiber-reinforced polymer composites have recently drawn attention as new materials for ballistic armor due to sustainability benefits and lower cost as compared to conventional synthetic fibers, such as aramid and ultra-high-molecular-weight polyethylene (UHMWPE). In the present work, a comparison was carried out between the ballistic performance of UHMWPE composite, commercially known as Dyneema, and epoxy composite reinforced with 30 vol % natural fibers extracted from pineapple leaves (PALF) in a hard armor system. This hard armor system aims to provide additional protection to conventional level IIIA ballistic armor vests, made with Kevlar, by introducing the PALF composite plate, effectively changing the ballistic armor into level III. This level of protection allows the ballistic armor to be safely subjected to higher impact projectiles, such as 7.62 mm caliber rifle ammunition. The results indicate that a hard armor with a ceramic front followed by the PALF/epoxy composite meets the National Institute of Justice (NIJ) international standard for level III protection and performs comparably to that of the Dyneema plate, commonly used in armor vests.

This research focuses on the development of a sustainable acoustic material comprising natural fibers of corn husk that were alkali modified by 1%, 2%, 5%, and 8% NaOH. The morphology and the acoustical, physical, and mechanical properties of the resulting fibers were experimentally investigated. Five different types of sample were produced in panel form, the acoustical properties of which were studied using a two-microphone impedance tube test. The porosity, tortuosity, and airflow resistivity of each panel were investigated, tensile tests were conducted, and the morphological aspects were evaluated via scanning electron microscopy. The sound absorption and tensile properties of the treated panels were better than those of raw fiber panels; the treated panels were of high airflow resistivity and had low porosity. Scanning electron micrographs of the surfaces of the corn husk fibers revealed that the different sound absorption properties of these panels were due to roughness and the lumen structures.

Fiber Reinforced Polymer Composites

This paper deals with tensile properties of natural fiber reinforced polymer composites. Natural fibers have recently found increasing use in various fields as an alternative to synthetic fiber reinforced polymers. Due to this they have become attractive to engineers, researchers and scientists. Natural fibers are replacing conventional fibers such as glass, aramid and carbon due to their eco-friendly nature, lesser cost, good mechanical properties, better specific strength, bio-degradability and non-abrasive characteristics. The adhesion between the fibers and the matrix highly influence the tensile properties of both thermoset and thermoplastic natural fiber reinforced polymer composites. In order to enhance the tensile properties by improving the strength of fiber and matrix bond many chemical modifications are normally employed. In most cases the tensile strengths of natural fiber reinforced polymer composites are found to increase with higher fiber content, up to a maximum level and then drop, whereas the Young’s modulus continuously increases with increasing fiber loading. It has been experimentally found that tensile strength and Young’s modulus of reinforced composites increased with increase in fiber content [1].
