“…In thick bundles of fibers, most of the infusion of the resin occurs through the capillary flow, which has a very low speed. As a result, the thicker the bundle of fibers, the more time it takes for complete infusion …”

Fiber metal laminates (FMLs) are hybrid structures made of fibrous composite layers that are located between thin metal layers and joined together by resin. In the current fabrication process, FMLs require prepreg and use of an autoclave or press. This will increase the cost of production and limit the size of the piece to the dimensions of the autoclave or press. Hence, there is an interest in finding methods of construction that are affordable and have no dimensional limitations but also does not reduce the quality of the part. Vacuum infusion is a convenient and economical way to provide high-quality composite components. In this article, the possibility to construct FMLs with this method, as well as the effects of different parameters such as the number of layers, the type of fiber, and the presence of holes in metal layers on the time and quality of parts, is investigated. The fibers used consisted of unidirectional fibers (300 and 600 g/m 2 ), woven, and CFM (300 g/m 2 ). The results show that, increasing the number of fibrous layers, metal sheets or using woven fibers increased the infusion time, and the presence of holes in aluminum layers or using CFM fibers reduced the infusion time. However, the presence of holes in aluminum layers significantly reduces the time of infusion but weakens the mechanical properties of the FMLs. The results of the tensile tests showed that, although the elastic modulus does not change, ultimate strength and fracture strain of the specimen containing holes were 9% and 27% less than the specimen without hole, respectively.

The demand for natural fiber composites in the automotive industry in both Europe and the United States has been forecasted to increase in the coming years. The natural fiber composites based on highly commercialized fibers such as flax, hemp, and sisal has grown to become an important sector of polymeric composites. However, little attention has been addressed to expanding natural fiber composites to include new sources of emerging natural reinforcements, such as reclaimed algae fibers, that have a multiple environmental benefits. Not only are extracted algae fibers biodegradable, the reclamation process has the added benefit of restoring health of waterways choked with algae. This study focuses on the processability of algae fiber–epoxy composites. Short fibers, chemically extracted from raw reclaimed algae, were prepared for natural fiber composite products in two ways. First, randomly oriented mats were produced using the wet-laid process to create layered, compression-molded laminates. Second, loose fibers were dispersed directly into the thermoset matrix to produce a bulk molding compound that was further compression molded into composite lamina. The effect of processing variables such as compaction pressure, temperature, and time were addressed. Moreover, the effect of fiber volume fraction ( υf) and fiber form were considered. Enhanced mechanical properties were found when 56% υf algae fiber was used for the compression-molded laminates composite. This variant exhibited an improvement on the flexural and tensile modulus of 70% and 86% when compared to the neat epoxy. However, the volume of porosity on the same variant was 11% due to lack of compression in some of the fibers. The effect of porosity on the theoretical stiffness was estimated by using the Cox–Krenchel model. Furthermore, an empirical exponential model was formulated to characterize the multi-scale effect of compaction pressure on the overall fiber volume fraction, υf.

“…To understand the properties of jute-based products, two types of experiments have been performed. The first type deals with the characterization of composites, where jute and other natural/artificial fibers are used as reinforcing materials [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. The main concern of these studies is to elucidate the efficacy of methods for improving the material properties of composites.…”

“…The main concern of these studies is to elucidate the efficacy of methods for improving the material properties of composites. The following issues have been studied: improving the dynamic mechanical properties of a jute composite [ 27 ], improving the adhesion between a matrix and fibers using chemically treated fibers [ 12 , 13 ], improving the performance of a composite by changing the weight percentages of fibers [ 13 , 14 ], improving the performance of a composite by changing the fiber length [ 15 , 16 ] and orientation [ 17 , 18 ], improving the performance of a composite through lamination [ 12 , 17 , 18 , 19 , 20 ], improving the performance of a composite by mixing jute fibers with other natural or artificial fibers [ 18 , 21 , 22 , 23 , 24 , 25 , 26 ], etc. Here, “improving performance” means improving the mechanical, thermal, environmental degradability, and durability properties of a composite.…”

Products made from natural materials are eco-friendly. Therefore, it is important to supply product developers with reliable information regarding the properties of natural materials. In this study, we consider a widely used natural material called jute, which grows in Bangladesh, India, and China. We described the results of tensile tests on jute yarns, as well as the energy absorption patterns leading to yarn failure. We have also used statistical analyses and possibility distributions to quantify the uncertainty associated with the following properties of jute yarn: tensile strength, modulus of elasticity, and strain to failure. The uncertainty and energy absorption patterns of jute yarns were compared with those of jute fibers. We concluded that in order to ensure the reliability and durability of a product made from jute, it is good practice to examine the material properties of yarns rather than those of fibers.
