Development of light weight sustainable pineapple/kevlar hybridized fiber and peanut husk cellulose toughened vinyl ester biocomposite for unmanned aerial vehicle applications

Abstract

The aim of this study is to develop a light weight hybrid biocomposite using pineapple and Kevlar fiber with peanut husk cellulose in vinyl ester resin for applications in unmanned aerial vehicles. This study focuses on how the silane treatment on fiber and cellulose particle influences the mechanical, fatigue and low velocity impact properties of this hybrid biocomposites. Using hand lay‐up technique, the biocomposite was prepared with cellulose loading ranging from 1 to 5 vol%. The results revealed that the 5 vol% of cellulose added composite had an improved tensile, impact, flexural, hardness and ILSS of 161 MPa, 224 MPa, 6.8 J, 84 shore‐D and 21.4 MPa. Moreover, the biocomposite with the inclusion of 3 vol% cellulose had an improved fatigue life count of 42 697, 29 821, 22 381 and 18 164 at 25%, 50%, 75% and 90% of UTS. Similarly, the 3 vol% cellulose reinforced composite showed an improved low velocity impact toughness of 12.36 J. The obtained results clearly indicated that these mechanically strengthened and highly toughened biocomposites could be used as working material for number of applications, especially in making of UAVs for the aerospace industry, automotive components for the transportation sector and structural material in domestic infrastructure.

Effect of adding Indiana red matta rice husk Si3N4 bioceramic on mechanical, wear, flammability and tensile creep behavior of corn husk fiber polyester composite

“…This increment in values is about 94 MPa, 3.22 GPa, 136 MPa, 4.75 GPa, 3.74 J and 87 shore‐D for tensile strength, tensile modulus, flexural strength, flexural modulus, Izod impact, and hardness respectively. The composite's mechanical characteristics are enhanced by the addition of the corn husk fiber that functions as a load bearing system for composite and ensured uniform distribution of fiber throughout the matrix 21 . Moreover the micro fibril nature of corn husk fiber reduced the stress intensity factor in the matrix thereby improved the load bearing capacity.…”

Applications of plastics in the automotive industry: Current trends and future perspectives

“…By integrating bio-based materials into automotive components, manufacturers reduce their reliance on finite and nonrenewable resources, promoting a circular economy through options such as composting or biodegradation at the end of a product's lifecycle. 82,83 An overarching strategy aimed at maximizing sustainability and recyclability involves the transition towards a circular economy model. This model encompasses a series of critical initiatives, including the implementation of end-of-life strategies such as design for disassembly and efficient material separation.…”

Synthesis and modification of poly (p‐phenylene terephthalamide) for production of light‐weight hybrid composite armors reinforced with polymer composite nanofiber mats

“…[34][35][36][37][38] Research efforts are therefore underway to develop different designs to improve the energy absorption capacity of para-aramid fabrics through interply/intraply hybridization with different types of synthetic and natural fibers, layering of different materials or matrices and impregnation with STF, micro/nano-particles or the combination of these. [39][40][41] However, the contribution of polymer-based nanofiber mats to the ballistic impact response of the textile laminated armor system has not yet been reported in the open literature, despite the promising improvement in the mechanical properties of composites with a very small nanofiber reinforcement (<10 wt%) due to their extremely high surface area/mass ratio.…”
