The Impact

The research toward environmentally friendly materials has devoted a great effort on composites based on natural fiber-reinforced biopolymers. These materials have shown noticeable mechanical properties, mainly tensile and flexural strengths, as a consequence of increasingly strong interfaces. Previous studies have shown a good interface between natural fibers and poly (lactic acid) (PLA) when these fibers present a low lignin content in their surface chemical composition (bleached fibers). Nonetheless, one of the main drawbacks of these materials is the hydrophilicity of the reinforcements in front of the mineral ones like glass fiber. Meanwhile, the behavior of such materials under impact is also of importance to evaluate its usefulness. This research evaluates the water uptake behavior and the impact strength of bleached Kraft softwood-reinforced PLA composites that have been reported to show noticeable tensile and flexural properties. The paper explores the differences between these bio-based materials and commodity composites like glass fiber-reinforced polypropylene.

Natural fiber-reinforced thermoplastic composites can be an alternative to mineral fiber-based composites, especially when economic and environment concerns are included under the material selection criteria. In recent years, the literature has shown how lignocellulosic fiber-reinforced composites can be used for a variety of applications. Nonetheless, the impact strength and the water uptake behavior of such materials have been seen as drawbacks. In this work, the impact strength and the water uptake of composites made of polypropylene reinforced with fibers from recycled newspaper have been researched. The results show how the impact strength decreases with the percentage of reinforcement in a similar manner to that of glass fiber-reinforced polypropylene composites as a result of adding a fragile phase to the material. It was found that the water uptake increased with the increasing percentages of lignocellulosic fibers due to the hydrophilic nature of such reinforcements. The diffusion behavior was found to be Fickian. A maleic anhydride was added as a coupling agent in order to increase the strength of the interface between the matrix and the reinforcements. It was found that the presence of such a coupling agent increased the impact strength of the composites and decreased the water uptake. Impact strengths of 21.3 kJ/m3 were obtained for a coupled composite with 30 wt % reinforcement contents, which is a value higher than that obtained for glass fiber-based materials. The obtained composites reinforced with recycled fibers showed competitive impact strength and water uptake behaviors in comparison with materials reinforced with raw lignocellulosic fibers. The article increases the knowledge on newspaper fiber-reinforced polyolefin composite properties, showing the competitiveness of waste-based materials.

Natural fibers from plants are gaining importance and may substitute wood in the production of wood plastic composites (WPC). To ensure continuity of fiber supply and sustainability of WPC industries, fibers of various types could be mixed together to obtain Mix WPC. However, research need to be carried out to identify the contribution of different fiber type collectively to the mechanical properties of Mix natural fiber polymer composite (NFPC). In this study, preliminary work on the use of natural fibre (NF) such as kenaf, sugar palm and pineapple leaf fibers in the preparation of Mix NFPC were carried out. Four different fiber mix samples with different fiber ratio and size were formulated using polypropylene (PP) as the polymer matrix. Montmorrilonite (MMT) filler was added at constant amount for enhancement of composite mechanical properties. Samples were mixed and prepared using a twin screw extruder and mini injection moulding resepectively. Individual fibers and NFPC prepared were characterized using thermogravimetric analyzer (TGA). Tensile, flexural and impact strength of the composites were determined. Generally, it was found that addition of fiber mix at 50% fiber loading enhance the tensile and flexural strength of the various NFPC with minimal exceptions. The impact strength of the composites were comparable to that of blank PP implying that addition of fiber gives additional advantage besides being eco-friendly. It was also found that higher kenaf loading and different size of fiber mix contribute positively to the various strengths measured. In addition to that, composition of individual fibers also contribute to the mechanical properties of the NFPCs

Usage of Natural Fiber Composites (NFC) is increased rapidly due to the bio degradability nature of the fibers. These natural fibers are mixed with synthetic fibers to obtain better mechanical properties. In this study, pine apple and glass fiber reinforced epoxy composites are developed and their mechanical properties were evaluated. Composites were prepared by varying the fibers content and by using hand layup process with glass moulds of size 160 x 160 x 3 mm3 . The obtained laminates were sliced as per the ASTM criterion to test the properties. Higher glass fiber content in the composite specimen obtained higher mechanical properties. The composites can be utilized for the purpose of manufacturing components like doors panels, desks, roof tops etc.

The Impact

The advanced development of biocomposites made of biodegradable polymers and natural fibers has initiated great interest because the resultant polymer will degrade absolutely and will not emit toxic substances. Among the biodegradable polymers, the poly(butylene succinate) and poly(lactic acid) have diverse commercial applications and the natural fiber such as wood flour is renewable and cheaper alternative to synthetic fiber. The properties of the composite made of poly(butylene succinate)/poly(lactic acid) blend and wood flour are not compatible due to the poor wettability and interfacial adhesion. Therefore, in the study presented, the Fusabond MB 100 D has been used to improve the interfacial bonding between poly(butylene succinate)/poly(lactic acid) blend and the dispersed wood flour. The results reveal that the addition of FB not only increases the tensile strength but also improves the impact strength of poly(butylene succinate)/poly(lactic acid)wood flour composite under high dynamic loading. Moreover, when Fusabond MB 100 D is added as a coupling agent to the poly(butylene succinate)/poly(lactic acid)wood flour composite results of X-ray photo spectroscopy, fracture surface morphology and dynamical mechanical property indicate the interaction between the poly(butylene succinate)/poly(lactic acid) blend with the wood flour.

Automobile bumper is an essential component that is commonly used to absorb the impact load during vehicle collisions, in fact it saves lives at such occurrences.In order to withstand the impact load, and the bumper deforms itself during collision and protects the passengers by havingthe proper cross section and the material selection. In this way, the study explores the mechanical characterization of fabricated composite and its structural analysis. Impact conditions have to be studied for improving the mechanical properties of the bumper during collision. The material chosen for analysis is jute and Glass fiber reinforced hybrid epoxy composite, considering its light weight and strength characteristics. Composites with two different fibre orientations (45°/90°) are fabricated using Hydraulic Compression Moulding technique. From experimental observations of jute and glass fiber reinforced hybrid composites, the orientation has significant effect on the structural and mechanical properties. The results are validated using the simulation of a bumper by impact modelling using CATIA software and impact analysis is carried out using ANSYS.
