In the present study, two sets of jute epoxy composites are fabricated by varying first fiber loading from 10 to 50 wt% at an interval of 10 wt% and then granite powder incorporated from 0 to 24 wt% in an interval of 8 wt% in the composites. The initial study is to prepare polymeric composites for wind turbine blade application and study the following physical to thermo‐mechanical properties including fracture toughness of the composites. The void content of the unfilled composites show in decreasing order (from 6.37 to 3.07%) with the increasing in fiber loading which satisfied well with the increasing in tensile strength from 28.33 to 34.2 MPa and flexural strength from 44.2 to 97.8 MPa, respectively. As far as particulate filled composites the void content shows reverse in trend (from 2.99% to 9.68%) with the increasing in filler content and which justifies the mechanical properties i.e tensile strength decreases from 33.72 to 32.27 MPa and similarly in case of flexural strength also. Whereas, hardness shows a unique behavior both in fiber reinforced and particulate filled composites in an increasing order from 29 to 44 Hv, respectively. Fracture toughness is observed to be constant for all considered crack lengths however, its value significantly improved with both type of reinforcement. The dynamic mechanical analysis shows positive effect of both the reinforcement for mechanical performance under cyclic stresses. Finally, Cole–Cole plot is drawn from the dynamic mechanical analysis results to verify the homogeneity of the composites. POLYM. COMPOS., 38:736–748, 2017. © 2015 Society of Plastics Engineers

“…Phenolic resins are preferred for aircraft interiors due to the extraordinary fire, smoke, and toxicity characteristics. Due to their excellent ablative properties, they are also used to manufacture carbon–carbon composites, rocket nozzles and heat shields . However, the major shortcoming is the evolution of volatiles during high temperature curing, which necessitates application of expensive processing equipment like autoclave, hydroclave, or hot press .…”

For reducing the cure temperature and improving the thermal stability and mechanical properties, a thermosetting resin system composed of novolak and bismaleimide (BMI) was developed by reactive blending and using dicumyl peroxide (DCP) as a novel curing agent. Novolak was allylated and reacted with BMI to produce bismaleimide allylated novolak (BAN), and the effect of DCP on flexural, impact and heat distortion temperature of cured resin were investigated. On the basis of improved mechanical and thermal properties at 0.5% DCP contents, the curing behavior of DCP/BAN resin system was evaluated by DSC analysis. Ene, Diels-Alder, homo-polymerization and alternating copolymerization which occurred in DCP/BAN resin system were further verified using FTIR at sequential cure conditions from 140 to 200 C. Kissinger and Ozawa-Flynn-wall methods were used to optimize the process and curing reactions of DCP/BAN resin system. The results showed that the addition of 0.5% DCP in BAN reduced the curing temperature and time of the modified resin. For evaluating process ability of the modified system, composite samples using polyvinyl acetyl fiber were molded and tested for flexural properties. The resulting samples showed better flexural properties when compared with the composite made with neat BAN. The modified 0.5% DCP/BAN resin system with good mechanical properties and manufacturability can be used for making bulk molding compounds and fiber reinforced composites required in various commercial and aerospace applications.

“…Composites were formed by compression molding at 1008C for 1 h. Bagasse reinforced composites were found to have considerably higher water absorption due to the incompatibility between the matrix and fibers that led to creation of voids and channels for water absorption. Hybrid composites containing higher levels of jute had lower water absorption indicating higher reinforcing effect [52]. Tensile strength and modulus of the hybrid composites was between that of the epoxy resin reinforced with jute or bagasse fibers.…”

“…However, having jute as the outside and bagasse as the middle layer provided higher tensile properties and also higher residue after thermal degradation. Final degradation temperature was 3458C for the jute/ bagasse/jute composites compared to 2848C bagasse/jute/ bagasse composites demonstrating that jute fibers were more thermally stable [52].…”

Polymer Composites

Composites are primarily made using matrix and reinforcement as major components but may also contain several other fillers or additives. A majority of the composites are made using synthetic fibers and polymers. However, in the last few decades, focus has been on developing biocomposites using renewable resources. Conventionally, biocomposites are developed using natural fibers such as jute, Kenaf, or Ramie as reinforcement and synthetic resins such as polyethylene, polypropylene and epoxy as matrix. Typically, biocomposites contain either the reinforcement or matrix which makes the composites partially degradable. Such partially degradable composites provide good properties, but the presence of a nonbiodegradable component, particularly as a matrix limits their biodegradability. Alternatively, composites that contain both the matrix and reinforcement from renewable resources which make the composites completely degradable have also been developed. However, these completely biodegradablebiocomposites do not have the desired mechanical properties and stability at high humidities or in aqueous environments which restricts their application. In addition, natural fibers and resins used in biocomposites have inherent limitations and also not easily processable. To overcome limitation of using a single reinforcement or matrix derived from bioresources, hybrid composites that contain more than one reinforcement or matrix are developed. Such hybrid composites are manufactured by either intimately mixing two or more fibers or other reinforcing materials or by placing different layers of the reinforcement and molding them into composites using one or more resins. Conventionally, hybrid composites refer to metallic and ceramic based reinforcement, matrix and fillers. Although hybrid biocomposites are gaining significant attention, the presence of multiple reinforcements and/or matrix makes it difficult to process and also to predict the properties of such composites. Hence, understanding the properties and potential of using multiple reinforcements and/or matrix materials from renewable resources to develop biobased hybrid composites is highly desirable. This article discusses hybrid composites that contain a major proportion of renewable materials. Hybrid composites not only provide better properties but could also lead to substantial cost reduction due to the incorporation of inexpensive raw materials. These composites show potential for use in aeronautical, sporting goods, wind power turbine blades, helmets and civil construction such as pedestrian bridges and many other applications. This review provides an overview of the biobased materials used to develop hybrid composites, their processability and their potential applications. POLYM.
