This research explores the synergistic impacts of grape stalk–derived lignin biopolymer and Celosia cristata microfiber reinforcement in polymer composites, examining their effects on mechanical, wear, thermal conductivity, and flammability properties. The stir-casting method is employed during the fabrication process to amalgamate the biopolymer a...

... the other hand, VCL3's hardness reached 85 thanks to the improved matrix stiffness, suggesting that the decrease is linked to the development of lignin clusters at greater volumes and the improvement of matrix rigidity. Figure 5 shows scanning electron micrographs of tensile specimens from several composite designations; these images provide important information about the fracture properties of these specimens. To better understand the complexities of the composite materials, each picture gives a window into the microstructural elements that affect mechanical qualities. ...Context 2

To better understand the complexities of the composite materials, each picture gives a window into the microstructural elements that affect mechanical qualities. Micro-voids inside the matrix, as shown in Fig. 5a, contribute to a decrease in mechanical strength. The structural integrity of the material is compromised, and its mechanical properties are decreased due to the fact that these voids serve as stress concentration locations. The spaces in the matrix are examples of localized weaknesses caused by inefficient load transfer. One important ...Context 3
... strength. The structural integrity of the material is compromised, and its mechanical properties are decreased due to the fact that these voids serve as stress concentration locations. The spaces in the matrix are examples of localized weaknesses caused by inefficient load transfer. One important part of the composite structure is shown in Fig. 5b, which is the adhesion of the Celosia cristata fibers to the vinyl ester matrix. A weaker link, as seen in the image, may lead to the fiber breaking under ...Context 4
... total performance is lowered because the bonding interface is weaker, making it more likely that the fiber matrix would separate under mechanical stress. Figure 5c shows, on the other hand, that the addition of lignin filler particles improves the fiber-matrix bonding scenario. By filling empty gaps, these particles improve the interfacial adhesion of the matrix and fibers. ...Context 5
... prevent voids from forming and to reinforce the composite as a whole, the filler particles work as reinforcing agents. Figure 5d shows a possible downside of using larger amounts of lignin particles. The picture shows where the matrix has become stressed due to the clustering of lignin particles. ...Context 6
... lignin particles. The picture shows where the matrix has become stressed due to the clustering of lignin particles. Mechanical qualities are diminished due in part to these stress spots, which are regions of localized increased rigidity. The material's structure can be affected due to the agglomeration's unequal stress distribution. To summarize, Fig. 5's SEM pictures ...Similar publications
The primary objective of the study is to examine the mechanical, wear, flammability and thermal properties of the vinyl ester biocomposite reinforced with silane-treated lignin biopolymer and Celosia argentea microfiber. Thus, the reinforcement of lignin biopolymer as filler particle into matrix by extracting from waste biomass along with natural f...
