Mechanical characterization of glass and jute fiber-based hybrid composites fabricated through compression molding technique

Abstract

Natural fibers, especially jute fibers, have gained interest in recent decades due to their attractive mechanical properties, high cellulose percentage, low cost, biodegradability, and easy availability. In the present study, flexural and drop weight impact behavior for different weight percentages of glass and jute fiber reinforced epoxy composites are studied experimentally according to ASTM standards. The hybrid composites were prepared through the compression molding technique. Numerical simulations were performed to investigate the predictive flexural response. The leading cause of error between experimental and numerical results is the manufacturing process and the reinforcement's woven nature. On the other hand, the impact strength was studied through drop weight testing at fixed 10 J energy. It is found that damage area decreases with increasing jute percentage in glass/jute hybrid composites, showing that jute fiber contributes more towards the composites' impact strength than glass fiber. Therefore, jute fiber can replace glass fiber in the glass/jute hybrid composite as a natural and eco-friendly constituent. The microscopic study reveals that the outer glass fiber layer helps minimize the stress distribution of jute fiber. A significant drawback of compression molding is the epoxy affluent areas in the composite.

Revealing the Dynamic Characteristics of Composite Material-Based Miura-Origami Tube

“…The proposed Miura tube in the study has several benefits; for instance, it can be (1) applied to various engineering fields, such as the core layer of a sandwich material, energy-absorbing structures [ 9 , 10 , 11 ], and so on; (2) fabricated from inexpensive two-dimensional metal materials but possess outstanding dynamic properties [ 33 , 34 ]; and (3) used as the initial design domain of a topology optimization to further enhanced the desired mechanical properties [ 57 , 58 , 59 , 60 , 61 ]. However, we still have some works in progress, for instance, fabricating a carbon fiber/epoxy resin-based origami tube [ 62 , 63 , 64 ], conducting modal tests [ 33 ], and performing a structural optimization to further enhance the dynamic properties of the origami tube [ 57 , 58 , 59 , 60 , 61 ]. These results will be published in another paper.…”

Effect of Ceramic Nano Fillers in Jute Fibre Composites

“…e appropriate optimization of this method's parameter could result in a higher or possibly composite answer for household shipments that include fences, chairs, and other items. Khalid et al [7] e natural fibre evolved composite reveals better mechanical overall performance in terms of tensile and flexural conduct compared to warmness. Epoxy/jute and polyester/jute composites are expected to be 58.23 MPa and 63.31 MPa, respectively.…”

4D Printing: Technological and Manufacturing Renaissance

“…SRMs or shape‐memory materials (SMMs) include shape‐memory polymers (SMPs), shape‐memory alloys (SMAs), liquid crystal elastomers, shape‐memory polymer composites (SMPCs), and shape‐memory hydrogels (SMHs). [ 34–36 ] SMAs are special type of programmable alloys which recapture their original shape upon triggering through external stimulus. These alloys exhibit a wide range of potential applications due to their excellent shape‐memory effect (SME) and super‐elastic properties.…”
