“…Coir has been accounted for as having the highest extension at break among common natural fibers, which allows it absorb strain more than other fibers [9][10][11]. Reinforcing polymer, for example, polyethylene with natural fiber/particulates to produce polymer composites has gained significant consideration because of their intrinsic properties [12]. Glass fiber has been an interesting option as reinforcement, however, despite the fact that glass fiber reinforced plastics have high quality, their fields of use are exceptionally restricted on account of its inherent higher cost of production [13].…”

“…Despite the volume of fiber reinforced polymer composites under investigation, most of the research efforts have been focused on either the characteristics of these polymers or the basic properties of the different phases that make up the composite [12,[27][28][29]. In our previous work [12,30], we identified a coir length which enhanced the mechanical and dynamic mechanical (viscoelastic) properties of our developed coconut husk filled composites. Hence, the present work focused mainly on the evaluation of the dynamic mechanical characteristics of the fabricated composite on exposure to an acidic environment.…”

This chapter describes an experimental investigation into the dynamic mechanical properties of coir and coconut husk particulate reinforced polymer composites which were prepared by the hot press method. The composite was immersed in a strongly acidic environment of pH 2.2 for a period of 14 and 28 days (14P and 28P). Values of storage modulus at different vibrational frequencies recorded for the polymers at low temperatures where the molecules are still tightly compressed and the region of first solid state transitions are:

“…Most of the studies mentioned above have observed that the mechanical properties of polymer composite increased with increasing CSP content. Furthermore, there are some recently published reports of hybrid polymer based composites using CSP and other natural materials including coir fibers [24][25][26][27][28]. Vignesh et al [24] carried out experiments using tensile and flexural tests of CSP and coir fiber reinforced polyester composites and found that the coir fiber predominates in enhancing the mechanical properties of CSP-polyester composites.…”

“…Vignesh et al [24] carried out experiments using tensile and flexural tests of CSP and coir fiber reinforced polyester composites and found that the coir fiber predominates in enhancing the mechanical properties of CSP-polyester composites. Vinod Kumar and co-workers [25] concluded that the mechanical properties (tensile and impact strengths) were less affected by the addition of CSP filler. Kuburi et al [26] and Bhaskar and Singh [27] concluded that the CSP and coir fibers are good reinforcing materials to reduce the consumption of resin as well as utilizing waste natural material without altering the properties required for load-bearing applications.…”

An attempt has been made to explore the effect of hybrid reinforcement on mechanical properties and dry sliding wear behavior of vinyl ester (VE) composites. Vinyl ester reinforced with alkali treated coir fibers (CF-VE), silanated aramid fibers (AFs) leading to fibridization and inclusion of coconut shell powder (CSP) with various weight proportions has been prepared resulting in hybridization. Effectiveness of treated fibers and CSP on mechanical and wear behavior of VE and their hybrids was evaluated. The density and hardness values of CF-VE composite increased steadily with inclusion of AFs and CSP. The tensile strength increased from 52 MPa at 0 wt.% AFs inclusion to a maximum of 76 MPa at 15 and 5 wt.% of AFs and CSP content. Further, it increased to a maximum of 78 MPa at 5 and 10 wt.% of AFs and CSP in CF-VE composite. The specific wear rate decreased more rapidly with the CSP content. Hence, it is deduced that hybrid VE (15CFs+5AFs) composite with 10 wt.% CSP is more effective against sliding wear. The type, geometry and dispersion of reinforcements contribute to the increased wear resistance. These results are important for the development of new composites incorporated with surface treated reinforcing materials such as CF and CSP, which will have significant application in automotive sliding or bearing components.

This paper presents experimental data using estimated approach to determine some mechanical properties of epoxy matrix based composites. For this reason, the epoxy matrix was made composite with the powdered materials obtained from different parts of the juniperus drupacea seeds. In order to obtain a homogeneous structure ultrasonic mixing technique was preferred. As an experimental estimation approach, the Taguchi method that is an alternative way to characterize complex composite structures, to come from above the problems and to investigate the effects of test parameters-factors by performing a few experiments was used. In the study, the L9 Taguchi orthogonal array has been preferred. Based on some production conditions; bio-reinforcement material has lowered the average hardness value to 4.22 and formed a more soft structure in addition to improving the tensile strength value by 46% compared to the neat sample. Parametric study showed that; the most important parameter affecting hardness and tensile strength are the mixing time and reinforcement ratio, respectively.
