Abstract The natural fiber have recently become attractive and been widely used as reinforcement material to replace synthetic fiber as a concern to environmental issue. However, there are some of natural fiber unable to perform well as reinforcement material due to their natural properties. In this research study, the corn stalk fiber was selected as natural fiber reinforced with polybutadiene adipate terephalate (PBAT) to form bio-composite materials. There are two type of PBAT used which are in pellets form and powder form. The objectives of using different type of PBAT are to identify their compatibility with filler and the dispersion of corn stalk fiber in both forms of matrix. Then, the both type of PBAT also compounded with difference loadings of corn stalk fiber. Lastly, their effect on tensile properties and absorption ability were identified. After the test is run, the composite of neat PBAT in powder form shows highest tensile strength and elongation at break but lowest in water absorption percentage compared to others. However, the composition of pellets PBAT with 30wt% of corn stalk fiber shows highest percentage of water absorption compared to others.

The biodegradable composite films were prepared from corn stalk microcrystalline cellulose as filler and polylactic acid (PLA) as polymeric matrix. The crystallinity, the tensile properties and the thermal properties of the composites were tested. The results show that the tensile properties and thermal properties were improved with the addition of corn stalk microcrystalline cellulose. When corn stalk microcrystalline cellulose account for 10% of the PLA quality, the initial decomposition temperature was raised by 34.38, tensile strength increased by 58.3% and elongation at break increased by 31.1% compared to those of pure PLA.

The development of bio-composites as biodegradable and renewable materials for sustainable technology are advantageous in creating a green and healthy environment. However, the application of natural fiber as a bio-composite material have been found to be restricted especially as it has lower thermal resistance in comparison to synthetic fiber. Therefore, the objective of this study is to investigate the influence of fiber orientations on the tensile properties at various tensile temperatures for unidirectional kenaf polypropylene (PP) composite. Samples were prepared by hot pressing process. In this study, kenaf long fibers that are produced from water retting process is use as a reinforcement agent while PP as a polymer in the composite fabrication. A tensile test was carried out at different temperatures (30°C, 60°C, 90°C, 120°C) for various orientations (0°, 45° and 90°). It was found that an increase of temperature will reduce the modulus and tensile strength where the highest reduction occurred between 60°C to 120°C and most significantly on the orientation of 45° and 90°, which is lower than pure PP. This concludes that the application of kenaf PP composite is optimum between room temperature with a cut-off temperature at 60°C.

Concrete Production

The use of synthetic fiber and natural fiber for concrete production has been continuously investigated. Most of the materials have become popular for their higher flexibility, durability, and strength. However, the current study explores the engineering properties of cement concrete reinforced with nylon and jute fibers together. Varying proportions and lengths of nylon and jute fibers were utilized in the concrete mixture. Hence, the combined effects of nylon and jute fibers on workability, density, water absorption, compressive, tensile, flexural strength, and drying shrinkage of concrete were investigated. Results showed that concrete with 1% of nylon and jute fibers together by the volume fraction showed a maximum enhancement of the compressive strength, split tensile strength, and flexural strength by 11.71%, 14.10%, and 11.04%, respectively, compared to the control mix of concrete at 90 days. However, the water absorption of concrete increased with increasing nylon and jute fiber contents. The drying shrinkage of concrete decreased with the addition of nylon and jute fibers together after 90 days. Thus, the sparing application of both nylon and jute fiber as discussed in this study can be adopted for concrete production.

Use of natural fiber as reinforcing material is the latest invention of polymer science in order to get higher strength with lower weight composite materials having several applications. In this present investigation banana fiber, a natural fiber, is used as the reinforcing material. Low density polyethylene (LDPE)-banana fiber reinforced composites were prepared using both untreated and bleached (treated) banana fiber and LDPE with 7.5, 15, 22.5 and 30% weight content of fibers by using compression molding technique. Physico-mechanical properties (e.g. tensile strength, flexural strength, elongation at break, Young's modulus) of different types of prepared composites were characterized. From this study it is observed that all these values have augmented up to a definite percentage. The tensile strengths and flexural strengths of the composites increased up to 22.5% fiber addition then started to decrease gradually. Young moduli of the composites increased with the increase of fiber addition. Water absorption also increased with the weight of the fiber. Whereas elongation at break decreased with increasing fiber loading. Mechanical properties of bleached banana fiber-LDPE composites were slightly higher than the untreated banana fiber-LDPE composites. Compared to virgin molded LDPE both tensile and flexural strengths and Young moduli of these LDPE-banana fiber composites were significantly higher. All the variable properties like tensile strength, flexural strength, and water absorption capacity showed a very significant role in these polymer composites.

Background: The technological enhancement in various disciplines enhances the demand for the new material which can replace the conventional materials. This has initiated the idea of composite materials. Synthetic fiber reinforced polymer matrix composites are being widely used due to its mechanical properties, but these fibers lack in terms of biodegradability, initial processing cost, recyclability and health hazard. An alternative to tackle these drawbacks can be found in natural fibers, that give an advantage in terms of strength to weight ratio, ease of availability and biodegradability. Methods: This work is aimed to determine the effect of hybrid basalt - banana reinforced epoxy composite and their effectiveness in substituting few conventional materials in terms of their mechanical properties, wear resistance and water absorption rate. Results: Basalt Banana Hybrid Composite (BBHC) is tested for their mechanical strength, hardness, impact strength, flexural strength, wear rate and water absorption rate. The test results of mechanical properties for the BBHC are compared to the other hybrid materials and conventional materials. Conclusion: The test results reveal that the hybrid basalt banana epoxy composite is a good substitute over various conventional materials. The water absorption test results reveal that the hydrophilic nature of the natural fibers reduces a lot after the hybridization.

In order to improve properties of natural fibers as reinforcement, different treatment methods have being adopted by researchers. However, the use of sodium hydroxide (NaOH) for the treatment of baobab pod fiber as reinforcement in low density polyethylene is sparsely reported. Therefore, this study, investigated the effect of 2 wt%, 4 wt% 6 wt%, 8 wt% and 10 wt%  concentration of NaOH on baobab pod fibers as reinforcement for low density polyethylene (LDPE). Two roll mill machine and hydraulic press at a pressure of 10 kN and temperature of 120oC aided the production of the composite. FT-IR was used to analyze the functional groups of the treated and un-treated fibers. The result showed the disappearance of the peak 1550 cm-1 corresponding to lignin after modification. Further, the composites were characterized for the following tensile strength (TS), modulus of elasticity (MOE), elongation at break, impact strength and water absorption. Preliminary studies on the effect of loading of the unmodified baobab fiber in the LDPE matrix showed desirable properties at 10 wt%, where fiber content was in the range of 5 wt% to 30 wt% at interval of 5 wt%. The composite produced from the 8 wt% NaOH modified fiber had the highest tensile strength, MOE, elongation at break. At this modification level, the tensile strength, MOE and elongation at break were about 75.48%, 92.18% and 28% respectively higher than the composite produced from unmodified fiber. Composite produced with 10 wt% NaOH modified fiber exhibited least water absorption of 1.80%, which was 50% lower than unmodified. These showed that the modification of the fiber improved the composite properties. These properties compared favorably with some reported properties for natural fiber reinforced polymer composites. http://dx.doi.org/10.4314/njt.v36i1.12

The effect of corn stalk content and compatibilizer on tensile properties and morphology of Low Density Polyethylene (LDPE)/Corn Stalk (CS) biocomposites was studied. The results found that the tensile strength and elongation at break decreased, but Young’s modulus increased with increasing CS content. The dispersion and interfacial adhesion between the CS filler and thermoplastic were important factors affecting the tensile properties of composites system. In order to improve the compatibility and interfacial adhesion, maleic anhydride polyethylene (MAPE) as compatibilizer was added into LDPE/CS biocomposites. The addition of MAPE has enhanced tensile properties and interfacial interaction between CS and LDPE biocomposites, as demonstrated in SEM study.

Studies in polymer composites reinforced with vegetable fiber show that they are enough sensitive to influences from environmental agents such as water and temperature. The moisture causes degradation of the mechanical properties of natural fiber reinforced composites to a large extent when compared to synthetic fiber reinforced composites. This is a consequence of the higher moisture absorption, and the hydrofilic nature of the natural fiber. In this sense, the purpose of this work is to study theoretically the water absorption in unsaturated polyester composites reinforced with caroá natural fiber (Neoglazioviavariegata) at the temperature 50°C. The composite had a weight composition of 30% caroá and 70% unsaturated polyester resin and dimensions of 20× 20× 3 mm3. Results of the average moisture content and moisture content distribution during the absorption process are presented and analyzed. Comparison between numerical and experimental data of the average moisture content presented good agreement. We conclude that the water absorption rate is faster in the vertex region of the composites.
