The automotive industry is under a growing volume of regulations regarding environmental impact and component recycling. Nowadays, glass fiber-based composites are commodities in the automotive industry, but show limitations when recycled. Thus, attention is being devoted to alternative reinforcements like natural fibers. Curauá (Curacao, Ananas erectifolius) is reported in the literature as a promising source of natural fiber prone to be used as composite reinforcement. Nonetheless, one important challenge is to obtain properly dispersed materials, especially when the percentages of reinforcements are higher than 30 wt %. In this work, composite materials with curauá fiber contents ranging from 20 wt % to 50 wt % showed a linear positive evolution of its tensile strength and Young’s modulus against reinforcement content. This is an indication of good reinforcement dispersion and of favorable stress transfer at the fiber-matrix interphase. A car door handle was used as a test case to assess the suitability of curauá-based composites to replace glass fiber-reinforced composites. The mechanical analysis and a preliminary lifecycle analysis are performed to prove such ability.

Natural fiber reinforced polymer composites became more attractive due to their light weight, high specific strength, biodegradability. However, some limitations e.g. low modulus, poor moisture resistance were reported. The mechanical properties of natural fiber reinforced composites can be improved by hybridization with synthetic fibers such as glass fiber. In this research, mechanical properties of short sisal-PP composites and short sisal/glass fiber hybrid composites were studied. Polypropylene grafted with maleic anhydride (PP-g-MA) was used as a compatibilizer to enhance the compatibility between the fibers and polypropylene. Effect of weight ratio of sisal and glass fiber at 30 % by weight on the mechanical properties of the composites was investigated. Morphology of fracture surface of each composite was also observed.

AbstractIn this work, the potential for using Millettia pinnata stalk for extracting cellulosic natural fibers and its subsequent use in reinforced composites was studied. The extracted fibers were characterized for its composition, mechanical, thermal stability and morphological properties. Compositional analysis showed that the fibers possessed 54% cellulose, 12% hemicellulose, 15% lignin and 11% ash. The tensile strength of the fiber was 310 MPa, which is comparable to cotton and linen. The tensile strength of the M. pinnata fiber-reinforced polypropylene composites was 17.96 MPa which was similar to other natural fiber-based composites. M. pinnata fibers appear promising for a wide range of applications including textiles and other typical composites applications.

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 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.


In this paper, tensile behaviour of the natural fiber composites such as the areca nut composites and the sunn hemp composites were determined. The fibers were arranged in different orientations such as the uniaxial, biaxial and the criss-cross arrangements. For both the types of fiber composites, specimens were made with and without the incorporation of E-glass fibers. Comparisons were done on the basis of fiber orientation, E-glass fibers incorporation and the type of natural fiber used. Initially, the fibers were treated with alkali, i.e. Sodium hydroxide (NaOH) in order to get better bonding at the fiber-matrix interface. The conventional hand lay-up technique followed by the soft compression molding technique was carried out for fabricating the composite specimens. It was inferred from the results that the tensile strength was more for uniaxial arrangement and the least for biaxial arrangement in case of both the fibers. Further, for both the fibers, E-glass fiber incorporation increased the tensile strength as compared to the non-incorporated E-glass fiber composites. Also, sunn hemp composites showed better tensile strength than areca nut composites. The research suggested that the areca nut and sunn hemp composites were assets to many potential applications that did not require very high load bearing capabilities. These examined composites can be considered as very reliable materials for fabrication of lightweight materials used in automobile industry, packaging materials, medical field, etc.

The developments in the field of composite materials are growing tremendously day by day. One such development is the use of natural fibers as reinforcement in the composite material. This is attributed to the fact that natural fibers are environmental friendly, economical, easily available and non-abrasive. Mixing of natural fiber with Glass Fibers is finding increased applications. In this present investigation Banana – Bamboo – Glass fiber reinforced natural fiber composites is fabricated by Hand – Layup technique with varying fiber orientation such as [0°G, 90°BM, 0°BN, 0°G], [0°G, 0°BM, +45°BN, 0°G] and [0°G, 0°BM, 90°BN, 0°G] and are tested for its tensile strength. The tensile strength of the fabricated composites is evaluated. The results indicated that the natural fiber composite with the fiber orientation of [0°G, 0°BM, 90°BN, 0°G] can withstand more load when compared to the samples with other fiber orientation. Nomenclature Used: BN – Banana fiber BM – Bamboo fiber G – Glass fiber

In recent years, in an attempt to substitute the conventional synthetic sound absorption material, natural fibers and their sound absorption properties have been increasingly studied. This is due to the fact that conventional synthetic fiber has potential health risks for human beings and significant environmental impact. In this review, existing and newly emerging natural fiber sound absorbers are summarized and highlighted in three categories: raw material, fiber assembly and composite. The sound absorption mechanism, several widely used prediction models and the popular acoustic characterization methods are presented. The comparison of sound absorption properties between some natural sound absorbers and glass fiber is conducted in two groups, i.e., thin material and thick material. It is found that many natural fibers have comparable sound absorption performance, some of them can be the ideal alternatives to glass fiber, such as kapok fiber, pineapple-leaf fiber and hemp fiber. Last, the conclusion part of this review gives an outlook regarding the promotion of the commercial use of natural fiber by means of theoretical study, efficient and environmentally friendly pretreatment and Life Cycle Assessment.

Recent decades have seen substantial interest in the use of natural fibers in continuous fiber reinforced composites, such as flax, jute and hemp. Considering potential applications, it is of particular interest how natural fiber composites compare to synthetic fiber composites, such as glass and carbon, and if natural fibers can replace synthetic fibers in existing applications. Many studies have made direct comparisons between natural and synthetic fiber composites via material coupon testing; however, few studies have made such direct comparisons of full structural members. This study presents compression tests of geometrically identical structural channel sections fabricated from fiber-epoxy composites of flax, jute, hemp, glass and carbon. Glass fiber composites demonstrated superior tension material coupon properties to natural fiber composites. However, for the same fiber mass, structural compression properties of natural fiber composite channels were generally equivalent to, or in some cases superior to, glass fiber composite channels. This indicates there is substantial potential for natural fibers to replace glass fibers in structural compression members. Carbon fiber composites were far superior to all other composites, indicating little potential for replacement with natural fibers.
