Natural fibers fulfill most requirements needed to replace synthetic fibers in thermoplastic composites. However, some disadvantages appear when natural fibers are used for composites. The poor compatibility between the hydrophilic fibers with the hydrophobic thermoplastic matrix leads to a weak interface and hence, poor mechanical properties. In this work, the effects of processing techniques (fiber surface modification and varying compounding ...

With increasing environmental awareness, the use of natural fibers are growing rapidly in light of market demands for "green" products. One such example is a pultruded natural fiber composite. In this study, the energy consumption of an innovative new pultruded composite integrating flax fibers with a resin having recycled content was compared to a regular glass fiber composite by using a life cycle perspective. This study begins to identify hotspots within the life cycle of green fiber composites to enable further improvements.
Natural fibres such as wood and vegetable fibre offer many advantages such as renewability, recyclability low specific gravity and high specific strength. In Malaysia most of the studies only focused on producing EFB as MDF and pulp and paper products. This paper reviews the development of natural fibres for building material and discusses the performance of oil palm empty fruit bunch (EFB) reinforced concrete roof slates produced in a preliminary experiment. Oil palm EFBs were used partially as cement replacement at levels of 0.5% and 1.0% and compared with the control specimens (0% fibre content). From the preliminary experiment, the physical properties of EFB roof slates were evaluated. Results show flexural strength and density decreased with increased fibre contents that were mixed with various water cement ratio. However, the results still exceeded the level set by the ASTM of 4 N/mm<sup>2</sup>. The preliminary results from the experiment suggest that oil palm EFBs have a potential to be a material component of reinforced mortar roofing slates with the appropriate water cement ratio and concrete mix.
Palm fibers one among the natural fibers whose leaf stalk and sheath portion were extracted manually. The extracted fibers were alkali treated which enhances fiber properties. In this study three composites were prepared namely, the first one with palm leaf stalk fiber, the second one with palm leaf sheath fiber and the third one with hybrids of palm leaf stalk/sheath fibers. All these fibers were sandwiched inside glass fibers with polyester resin matrix. The composite plates so prepared were tested as per ASTM standards. After various tests it can be noted that the hybrid composite shall be used for fabricating automobile parts like car bumpers, under body shield, etc.
This article highlights the development of an eco friendly polymer composite with natural fibers as reinforcement. The natural fibers are taken from palm tree namely; palm leaf stalk portion. It was sandwiched with artificially available glass fibers. The commercially available polyester resin blend with coconut shell filler in nano form was used as matrix to sandwich these composites. Portions of the extracted palm leaf stalk fibers are treated with potassium permanganate solution to enhance their properties while the remaining fibers are kept raw. For experimentation two set of plates one as untreated and other as alkali treated were fabricated using hand lay-up method. Specimens cut from the sandwiched composite plates were mechanically tested according to the ASTM standards. Experimental results reveal that the alkali treated palm leaf stalk fiber based polymer composite shows appreciable results than the untreated one. SEM analysis explores fewer voids for treated fibers. Hence the developed composite can be recommended for fabrication of automobile parts.
Natural fibers fulfill most requirements needed to replace synthetic fibers in thermoplastic composites. However, some disadvantages appear when natural fibers are used for composites. The poor compatibility between the hydrophilic fibers with the hydrophobic thermoplastic matrix leads to a weak interface and hence, poor mechanical properties. In this work, the effects of processing techniques (fiber surface modification and varying compounding pressure) on the mechanical properties of rice husk-polypropylene composite were investigated. The results showed improvement in mechanical properties for the treated composites (tensile strength, impact energy and hardness), with the mercerized sample having the highest improvement. The trend of results suggest that there is a need for further work on the optimization of the fiber-matrix interface for improved mechanical properties to be achieved.
Hygric strain behaviour of hybrid natural composites was found out experimentally. Hybrid composites are prepared through hand layup technique using pineapple / jute fibers of 40:0, 30:10, 20:20, 10:30 and 0:40 ratios. The overall fiber volume fraction was fixed at 0.4Vf. A separate test setup has been designed for determination of hygric strain (β) in moisture environment. Changes in radius of curvature for each specimen were measured periodically with respect to time. Coefficient of hygric strains are determined from weight gain and change in radius of curvature.
High strength, high modulus fibers such as Kevlar, Spectra, Dyneema and Vectran each have unique properties that require special consideration during the rope design and selection process. The author lists the seven most common types of synthetic rope construction. These are twisted strand, cable laid, single braid (plait), braided braid, double braid and jacketed parallel core rope. The advantages and applications of each type are described.
Increasing the problem of Global warming, green house effects, climate changing, etc. we want tosave our earth. If save our earth, our using/manufacturing products do not affect earth or not spoil the earth. So we want to make eco friendly products. This type of eco friendly products are manufacturing by major constituents of Natural or natural composite materials. Composite materials constitute a significant proportion of the engineered materials market ranging from everyday products to sophisticated niche applications. Natural fibers are worth as weight-saving materials. Natural fibers have been used to reinforce materials for over 3,000 years. Natural fibers have the advantage that they are renewable resources and have marketing appeal. Due to the demand and needs we want to find out new combination eco- friendly materials either recyclable or bio degradable. In this fibers may be using for bio degradable/ recyclable packaging, sealing, and fabrication applications. So we want to study the properties of Maize fibers. Alkaline treating is essential one of Natural fibers treating. Alkaline treated Maize fibers properties are having better Tensile and elongation compare to raw Maize fibers.
In this study discusses the design of automotive bumper composite materials using rice straw fiber - epoxy, the method used in the process is filament winding method with the addition of NAOH and without NAOH on the cleaning process of rice straw fibers from impurities such as silica and lignin. The tensile result test which has been done is the fiber volume fraction of 10%, 20%, 30%, and 40% which obtained an average tensile strength 10% as 6.43 GPA, for 20% as 8.89 GPA, for 30% as 14.295 GPA, and 40% as 5.55 GPA. The composite material of epoxy rice straw fibers with the addition of NAOH obtained tensile test results at volume fraction of 10% as 6.99 GPA, 20% as 10.69 GPA, 30% as 14.76 GPA, and 40% having tensile strength as 8.54 GPA. These three volume fractions meet the criteria for automotive bumper material with tensile strength as 8.09 GPA.
Increase of awareness among people has increased the demand for green products. Other synthetic materials such as plastic and fibreglass has been reduced because of the environmental concern. Reinforcement with other green materials such as lignocellulosic materials has been done to reduce the dependency on synthetic material. Kenaf (Hibiscus cannabinus L.) fibres have the biggest potential to be used as a composite product and also as reinforcement in the composite products. Lignocellulosic materials including kenaf face some of problems when used as a reinforcement material with synthetic materials especially plastic based materials such as polypropylene and polyester. This problem is related to the properties of the fibres and the synthetic materials thus would reduce the mechanical properties of the product manufactured. Modification of the surface by solution treatment has been the popular method for improving the mechanical properties. In this study modification using Sodium Hydroxide or NaOH at three different concentration has been conducted to investigate the influence on the mechanical properties in terms of elasticity and strength properties of the composite material manufactured. The polyester composites were manufactured and tests according to ASTM D790-02 for bending test. Six replications of each type were tested and the values were evaluated using statistical analysis software. All the samples for both MOR and MOE showed significant differences for each type. Based on the result the highest value of the polyester composite was the kenaf that treated with 3% of NaOH solution for both MOR and MOE value.
