Experimental Investigations on the Mechanical Characteristics of Natural Fiber Particle‐Reinforced Polymer Composites under Cryogenic Environment

Abstract

In the past few years, researchers have turned away from previous metals and minerals and more towards lightweight materials throughout addition to creating lightweight, better effective composites for special tasks. The composite materials were created by employing the most advantageous hand layup approach. To attain the aforementioned goals, the following limitations were implemented: at various levels, (i) coconut shell powder, (ii) walnut powder, and (iii) cryogenic treatment hours are all accessible. At 77 K, the laminated composite was put in a cryogenic chamber. Tensile, flexural, and interlaminar shear strengths were all tested mechanically. In comparison to 100 μm coconut shell powder-based particle composites, 80 μm walnut shell composites gave the maximum mechanical strength, while 10 wt% coconut shell powder and walnut and 80 wt% polyester also had a beneficial impact. The morphological behaviour of the particulate material was detected using a scanning electron microscope (SEM).

Analytical modeling and experimental estimation of the dynamic mechanical characteristics of green composite: Caesalpinia decapetala seed reinforcement

“…The 80 μm particle size exhibited enhanced dispersion quality in the matrix due to increased interaction at the boundary surface. 25 Although, there are many reports related to the reinforcement of natural filler into polymeric matrix, this is a unique natural filler, not explored before. Most studies are restricted to packaging applications or for antioxidant and antimicrobial properties.…”

“…SEM images showed that due to the reduction in the size of the filler, better interface bonding was achieved between the filler and matrix, thus improving the mechanical strength.
