“…Impact strength is important in most applications because the ability of structures to withstand repeated impacts is critical to the design's robustness, particularly in the transportation and consumer goods industries. As a result, the ability of structures, especially in the transportation and consumer goods industries, to withstand repeated impacts is critical to the robustness of the construction, according to numerous studies of polymer blend effect on impact tolerance [30][31][32] The behaviour of advanced materials suitable for impact resistance was developed and studied by material researchers and designers, therefore, eco-friendly and biodegradability are the most favoured requirements of making green composites, however natural bers, biopolymers and bio-llers could be utilised as sustainable additives for manufacturing biodegradable products [33,34] From numerous bioresources, a number of epoxy thermosets have been synthesized and the challenges and opportunities in developing sustainable epoxy thermosets and materials from bio-based monomeric phenols are presented in various results of mechanical properties such as impact resistance and ame-retarding ability [34,35] Therefore, in the impact resistance of bio-phenolic/epoxy polymer blends were shown in Fig. 7 has resulted the impact resistance was gradually increased as bio-phenolic loading increase from 5 wt% to 20 wt%.…”

Nowadays, researchers continue studies for alternative materials to replace the redundant petroleumbased products. The combination of various polymer mixture process mainly from bio-polymer material as a matrix property could reduce the dependence over petroleum-based polymer, thus the dangerous residue waste from the synthetic polymer in the fabrication process could be eliminated and produce better composite material with lower cost and high performance of composite material in numerous applications. In this study, the effect of bio-phenolic loading and curing temperature on the mechanical properties of bio-phenolic/epoxy polymer blends was investigated. Bio-phenolic/epoxy polymer blends were fabricated with different loading of bio-phenolic resin (5(P-5), 10(P-10), 15(P-15), 20(P-20) and 25(P-25) wt%) and different curing temperature was used which is 100 ℃, 130 ℃ and 150 ℃. The overall mechanical properties of bio-phenolic/epoxy polymer blends were improved as bio-phenolic loading increase and curing temperature increase. Based on the analysis, bio-phenolic/epoxy polymer blends with 20 wt% bio-phenolic showed the best overall mechanical properties. Besides that, 150 ℃ curing temperature was the most suitable curing temperature for bio-phenolic/epoxy polymer blends based on the overall mechanical properties.

“…The polymer composites using inorganic nanomaterials as fillers have attracted much attention owing to their distinctive properties and various potential applications in the construction, automotive, aerospace and electronics industries. [5][6][7][8] In order to enhance the functionality and performance of a polymer nanocomposites, thermally conductive inorganic fillers like silicon carbide, [9] aluminum nitride, [10] aluminum oxide, [11] boron nitride, [12] etc., and metal oxide fillers such as SiO 2 and TiO 2 have been explored. [13,14] Noble metals such as gold and silver can also be used, however with limited applications due its expensive nature.…”

Recently, boron nitride (BN) based materials have received significant attention in both academic and industrial sectors due to its interesting properties like large energy band gap, good resistance to oxidation, excellent thermal conductivity, thermal stability, chemical inertness, significant mechanical property and widespread applications. This review article deals with the preparation and properties of boron nitride and its nanocomposites with various polymers. Diverse polymers have been explored for the preparation of boron nitride filled polymer nanocomposites by adopting different mixing methods. Properties of the resulting polymer nanocomposites mainly depend up on filler size and dispersion, mixing conditions and type of interaction between polymer matrix and the filler. Herein, the structure, preparation and properties of various boron nitride based polymer nanocomposites are reviewed in detail along with a brief overview of different classes of BN nanomaterials.

Polymer fiber composites are increasingly being used in many industries, including the defense industry. However, for protective applications, in addition to high specific strength and stiffness, polymer composites are also required to have a high energy absorption capacity. To improve the performance of fiber-reinforced composites, many researchers have modified them using multiple methods, such as the introduction of nanofillers into the polymer matrix, the modification of fibers with nanofillers, the impregnation of fabrics using a shear thickening fluid (STF) or a shear thickening gel (STG), or a combination of these techniques. In addition, the physical structures of composites have been modified through reinforcement hybridization; the appropriate design of roving, weave, and cross-orientation of fabric layers; and the development of 3D structures. This review focuses on the effects of modifying composites on their impact energy absorption capacity and other mechanical properties. It highlights the technologies used and their effectiveness for the three main fiber types: glass, carbon, and aramid. In addition, basic design considerations related to fabric selection and orientation are indicated. Evaluation of the literature data showed that the highest energy absorption capacities are obtained by using an STF or STG and an appropriate fiber reinforcement structure, while modifications using nanomaterials allow other strength parameters to be improved, such as flexural strength, tensile strength, or shear strength.
