TL;DR: In this paper , the authors provide an overview of the bast fibers and their composites, properties enhancement techniques, overall mechanical behaviours and thermal stability with suitable applications for aeronautical, automobile, construction, chemical, and biomedical applications.
Abstract: Composite materials are revolutionizing to realize the demanding needs of aeronautical, automobile, construction, chemical, and biomedical applications. The natural fiber composite is chosen as one of the best choices among composites due to its sustainable goods like eco-friendly nature, better properties and Greenhouse gas (GHG) balance. Furthermore, the bast fiber composites are identified as promising industrial composites based on the availability, strength-to-weight ratio, manufacturing ease, and economics for commercialization. However, product quality and production volume significantly influence commercial adoption of the bast fiber composites. Especially the product quality primarily suffers due to climatic conditions, damage while harvesting, extraction method, retting issues, and extraction location. Consequently, this review aims to provide an overview of the bast fibers & their composites, properties enhancement techniques, overall mechanical behaviours and thermal stability with suitable applications.

TL;DR: In this paper, the performance of stainless steel wire mesh-reinforced hydrophilic fiber with epoxy (LY556) and vinyl ester resin was revealed. And the fabricated hybrid composite performances were deliberated through different characterizations such as tensile, hardness, flexural, wear, impact, water absorption and oil absorption as per ASTM standards.
Abstract: Natural fibers become one of the inevitable materials in engineering applications, and they gain popularity among engineers, researchers, and scientists due to their remarkable properties. This paper reveals the performance of stainless steel (SS) wire mesh-reinforced hydrophilic fiber with epoxy (LY556) and vinyl ester resin. Eight different types (H1 to H4 and F1 to F4) of hybrid composites were fabricated with hemp and flax fiber using hand layup technique. The fabricated hybrid composite performances were deliberated through different characterizations such as tensile, hardness, flexural, wear, impact, water absorption and oil absorption as per ASTM standards. The tensile test results depict that hemp/epoxy composite (H2) with wire mesh reinforcement shows 23.4% higher strength than H1 composite; likewise, hemp/vinyl ester composite H4 shows 13.7% higher strength than H3 composite. The flexural strength of the F2 composite has been found to be 11.9% higher than the F1 composite; similarly, composite F4 shows 32.1% higher strength than the F3 composite. The water absorption test clearly indicates that the composites with wire mesh (H2, H4, F2, and F4) absorbs a minimum percentage (29.5% to 31.8%) of water than the composite without wire mesh. The wear analysis shows that the H2 composite requires minimum frictional force (21.6%) than H3 composite. The obtained SEM image confirms the cup and cone fracture of wire mesh, brittle fracture of the matrix, and no evidence of debonding between matrix and wire mesh in the composites.

TL;DR: In this article, the influence of drilling and material variables on thrust force, torque and delamination of fiber reinforced thermoset composites was investigated experimentally and the results showed that the presence of sand filler in continuous-winding composites not only raised the values of cutting forces and push-out delamination but also increased their values with increasing cutting speed.

TL;DR: In this paper, natural rubber was reinforced with sisal and oil palm fibers and was subjected to dynamic mechanical analysis to determine the dynamic properties as a function of temperature, which is due to the increased stiffness imparted by the natural fibers.
Abstract: Natural rubber was reinforced with sisal and oil palm fibers and was subjected to dynamic mechanical analysis to determine the dynamic properties as a function of temperature. The storage modulus E′ was found to increase with weight fraction of fiber. This is due to the increased stiffness imparted by the natural fibers. Loss modulus increased with loading while the damping property was found to decrease. The fibers were subjected to alkali treatment of different concentrations namely 0.5, 1, 2, and 4% and the dynamic properties were studied. In the case of composites containing chemically modified fibers, storage modulus and loss modulus were found to increase. Scanning electron micrographs of tensile fracture surfaces of treated and untreated composites demonstrated better fiber–matrix bonding in the case of the former. POLYM.

TL;DR: In this article, the performance of glass/sisal hybrid composites focusing on mechanical (flexural and impact) and dynamic mechanical analyses (DMTA) was evaluated with different fiber loadings and different volume ratios between glass and sisal.
Abstract: This work aims to evaluate the performance of glass/sisal hybrid composites focusing on mechanical (flexural and impact) and dynamic mechanical analyses (DMTA). Hybrid composites with different fiber loadings and different volume ratios between glass and sisal were studied. The effect of the fiber length has also been investi- gated. The densities of the composites were compared with the theoretical values, showing agreement with the rule of mixtures. The results obtained in the flexural and impact analysis revealed that, in general, the properties were always higher for higher overall reinforcement content. By DMTA, an increase in the storage and loss modulus was found, as well as a shift to higher values for higher glass loading and overall fiber volume. It was also noticed an increase in the efficiency of the filler and the calculated acti- vation energy for the relaxation process in the glass transi- tion region. The fiber length did not significantly change the results observed in all analyses carried out in this work. The calculated adhesion factor increased for higher glass loadings, meaning the equation may not be applied for the system studied and there are other factors, besides adhe- sion influencing energy dissipation of the composites.
