“…Moreover, natural fibers as reinforcements in polymer composites offer a viable way to reduce weight in automotive applications because of their low density (1.5 g cm −3 ) compared to synthetic glass fibers (2.7 g cm −3 ). These fiber-reinforced polymer composites may have a possible weight reduction of about 90% [8][9][10]. Polymer composites based on natural fibers such as coir (CF), rice husk (RF), wood (WF), banana (BF) and sugarcane (SF) are more economically and environmentally friendly and show promise for use in the vehicle's semi-structural and structural components [11,12].…”

The objective of this work is to enhance the thermal conductivity and electrical properties of polymer hybrid composites through a systematic novel Grey Relation Grade Analysis (GRGA) optimization approach. This involves reinforcing the hybrid composites with hexagonal Boron Nitride (hBN) and various kinds of natural fibers or fillers. The development of a unique technology to produce multiphase composites using 2% of natural fibers or fillers such as coir fiber (CF), rice husk filler (RF), wood filler (WF), banana fiber (BF) and sugarcane fiber (SF) along with hBN (1, 3, 5 wt.%) particulates as reinforcements in epoxy matrix. The Taguchi L15 matrix array is utilized to fabricate interlaced composite samples via hand layup molding. Ultrasonic waves are used to ensure the uniform distribution of hBN filler into the matrix. Analysis of variance (ANOVA) and GRGA reveal the significant results. It shows that the multiphase hybrid composites exhibit good thermal conductivity when higher content of hBN (5 wt.%) particulate for all the micro particulate polymer (MPP) composites. Multi-response optimization shows that the micro banana fiber (2 wt.%) interlaces with hBN (5 wt.%) composite exhibits the higher thermal conductivity and electrical resistance compared to all other natural fiber interlaced composites. The aforementioned MPP composite has thermal conductivity of 1.03 W/m.K and electrical resistance of 279.88 Giga Ohms. Besides, the wood filler interlaced hBN (5 wt.%) composite shows the minimum dielectric constant compared to all other natural fiber composites. This desirable result is caused by the proper dispersion of hBN with the matrix which encourages interlocking with the fiber and the matrix. Maximum electrical resistance is observed for composite containing 5 wt.% of h-BN and 2 wt.% of BF. The developed MPP composite could be used in heat shields, electrical insulation components, and interior automotive components like dashboards, luggage compartments and interior walls.

“…Among the plant-based natural fiber, flax fiber has higher mechanical and dynamic properties due to the high cellulose content and less water-absorbent substances like wax, hemicellulose, lignin, and pectin content. 5,6 A new Caryota natural fiber laminate has been manufactured (varying weight fraction of 10-45 wt%). Their impact, bending, and tensile qualities were assessed.…”

In fiber metal laminates (FMLs), the order in which fibers with different natural properties are stacked is very important for making materials that absorb vibrations and have good mechanical properties for structural applications. Hence, the present study focuses on the mechanical and vibration characteristics of FML designed with multi‐order energy‐absorbing flax fiber and high‐strength basalt fiber stacking covered with titanium sheets. The fabricated FMLs were designed with titanium/basalt fiber laminate (Ti/B), titanium/flax fiber laminate (Ti/F) and titanium/multi‐order‐flax‐basalt fiber laminate. The mechanical characteristics including tensile, flexural, and impact strength; and vibration characteristics of prepared FMLs were investigated. The higher tensile and flexural strength were revealed in an FML consisting of basalt layers (Ti/B) laminate than the flax core part (Ti/F) due to the strongness of basalt fiber, increasing the capability of load‐bearing of composites. Ti/B FML showed a maximum tensile strength and flexural strength of 412 and 450 MPa. Furthermore, flax fiber absorbs more energy, so the flax layer's inbuilt structure increases energy absorption during impact and vibration testing. Ti/F exhibits the highest impact strength (427.8 kJ/m2) and Ti/B exhibits the lowest impact strength (312.5 kJ/m2) because flax fibers are more ductile than basalt fibers, increasing the toughness of the FML. Ti/F FML structure, the greatest natural frequency of modes 1, 2, and 3 (549.03, 715.07, and 956.15 Hz) was observed. Natural fiber hybridization designed for FML, such as the Ti/B/F laminate, improved mechanical and vibration properties, making it suitable for structural applications.Highlights Fiber metal laminates were designed with titanium/flax/basalt. FMLs stacked composites significantly affect the mechanical properties. The basalt fiber, increases the capability of load‐bearing of FMLs. The damping of FMLs increases with the increase in flax fiber layers. Flax‐basalt fibers stacked FMLs produce tunable impact and vibration energy.
