Nowadays, many industries are shown interest in the hybrid composites, natural fibers, and reinforced materials due to reduction of the weight. The reason is that it will not affect environmental conditions. This experimental investigation identified the mechanical properties of hybrid composites. The hybrid composite materials are extensively used by E-glass/epoxy, carbon, and titanium alloy. Composites have good strength and less weight. The highest challenge of the automobile industry is to r
The fiber-filled polymer composite is one of the best materials which provides a symmetrical superior strength and stiffness to structures. With the strengthening of people’s environmental protection and resource reuse consciousness, the development of renewable materials, especially natural fiber-filled polymer composites, is receiving great attention. This study investigated the mechanical properties of polymer composites incorporating waste materials from the food processing industry and agri
In the last twenty years, the use of cellulosic and lignocellulosic agricultural by-products for composite applications has been of great interest, especially for reinforcing matrices [...]
The current study reviews provide a brief overview on the properties of natural fiber and natural fiber reinforced composites like chemical, physical, mechanical properties and thermal behavior which is an emerging area in polymer science. The unique properties of these composites are based on the attributes of the individual components, as well as the relative numbers and arrangements of those components within the material system. The widespread acceptance of composites reinforced with natural
Kenaf (Hibiscus cannabinus) stem which consists of whole stem (KWS), core (KC) and bast (KB) were used to fabricate homogeneous and hybrid kenaf-rubberwood particleboards. Two types of panels namely homogeneous (100%RW, 100%KWS, 100%KC and 100%KB) and hybrid (70%RW- 30%KWS, 70%RW- 30%KC and 70%RW30%KB) particleboards were manufactured and examined through compaction and void evaluations. Findings show that hybrid panels consisting of 70% RW and 30% KWS and homogeneous 100%KWS give better compact

Abstract Commingling offering efficient engineering of dry prepregs has become an important technique for thermoplastic composites fabrication. Polypropylene is among the most consumed materials while preparing commingled thermoplastic preforms. However, the overall behaviors of composites may differ depending on the nature of reinforcing fibers. The study focuses on the development of commingled thermoplastic composites using polypropylene with different natural and synthetic fibers. Carbon, gl

The transportation and automotive industries are slowly integrating biocomposite materials into products where the economics make sense; this typically means a short manufacturing cycle time, not using expensive prepreg, and with little waste generated from the process. In a previous investigation into the use of biocomposites for electric bus seats and backs, three different material systems (hemp, flax, and pure cellulosic fibers, each paired with a high-bio-content epoxy) and two manufacturin
This study investigated the possibility of furniture factory waste sawdust (FFWS) utilization in polypropylene (PP) composites and producing furniture support leg prototypes. Test samples were manufactured using a single screw extruder and injection molding machine utilizing 10, 15, 20, 25, 30, and 35% by weight of FFWS and 0% or 3% maleated polypropylene (MAPP). Selected mechanical and physical properties of manufactured samples were determined. The presence of FFWS and MAPP significantly impro
Biocomposite materials made of natural plant fibers are becoming a viable alternative to the use of synthetic ones such as glass fibers, thanks to many economic, ecological, and technical benefits. However, their massive use in the industry requires optimal control of their mechanical performances, which constitutes a real scientific issue to be overcome. Indeed, biocomposites suffer from an important variability in their mechanical properties because of their multiscale structure, natural growt
Abstract This study aims to develop composite plates using silkworm cocoon waste- and hybrid silkworm cocoon waste-reinforced polymer composite using epoxy resin as a matrix to replace synthetic fibers in bulletproof plates. The fabrication involved mixing 70 g of silkworm cocoon waste with 240 g of resin and 70 g of ultra-high molecular weight polyethylene, followed by cold compression molding. Tensile and impact tests on the resulting samples, using a standardized 9 mm projectile, showed a ten
The development of additive manufacturing technologies has the advantage of producing more economical and efficient products. This trend is supported by the fact that this technology is extensively developed, so that it has easy platforms to use,
Natural fiber has emerged as a viable alternative to synthetic fibers like glass, carbon, and Kevlar for the development of polymeric composites. Present study focused on Thermo-gravimetric analysis (TGA), Differential thermal analysis (DTA), and Fourier transform infrared spectroscopy (FTIR) of the reinforced fibers and developed composites. HR-X-Ray Diffraction of neat epoxy, jute, hemp, and flax fibers was also performed. For TGA, as the temperature increases up to 2500C, thermal degradation
This study represents the first works on the manufacture of reinforcements for composite applications such as yarns and fabrics using a tropical fiber extracted from the bast of the Cola Lepidota (CL) plant. Different types of products were produced, including twisted and untwisted yarns and woven and quasi-unidirectional fabrics to manufacture composite samples. At each scale, experimental characterizations of textile and mechanical properties were carried out; these properties are compared to
The requirements of sustainable development of the economy force the replacement of the previously used composite materials in the production of elements not only with lighter, but also more durable materials. These materials should meet more and more stringent environmental protection requirements. This study aimed to determine the possibility of introducing a polymer structural composite reinforced with natural fiber into the structure of the hull of vessels instead of the commonly used polyme
The composite group investigates endlessly the features of natural fiber/thermoplastic matrix composite materials to improve recyclability, use of renewable sources, and reduce material costs. In this context, the development and use of biodegradable polymers for composites is considered one of the important strategies for reducing environmental challenges. Here, axially oriented fibers incorporated in conforming matrices make up fiber-reinforced composites. Due to the high viscosity of molten P
Incorporation of natural fibres into polymers to manufacture biocomposites is a way of limiting the environmental impact of these materials. However, the fibres quality is essential to fulfil their assigned role as reinforcement in biocomposites. The extraction of fibres from hemp stems requires a retting step. Retting is a bioprocess applied to plant stems to easily separate fibres from the central woody part. Nowadays, this process is carried out directly on the field in an empirically way due

Abstract Strategic investments in biorefinery projects are increasingly being made, and involve non‐traditional decision making, especially considering the technology and market risks involved. From the investor's perspective, the decision‐making process leading to product/process combinations for implementation as a biorefinery to achieve a sustainable business model and good economic returns is not obvious. Typical metrics used for investment decision making have some limitations regarding the

This study presents the mechanical performance enhancements of jute fibre composites, manufactured from two newly developed novel jute fibre unidirectional (UD) preforms, namely, stitching-based and sizing-based examples. To increase the use of jute fibres, which are naturally abundant and inexpensive, and to provide research into the use of mechanically advantageous continuous unidirectional (UD) preforms in composites (which are still limited in use), this study employed polyvinyl alcohol (PVA
The incorporation of intermittent renewable energy sources into a consistently controlled power transmission system hinges on advancements in energy storage technologies. Sodium ion batteries (SIBs) are emerging as a primary and viable alternative material due to their electrochemical activity, presenting a potential replacement for the next generation of lithium-ion battery (LIB) energy storage materials. However, this transition may necessitate significant alterations in the anode material, gi
