There is more demand for natural fiber-reinforced composites in the energy sector, and their impact on the environment is almost zero. Natural fiber has plenty of advantages, such as easy recycling and degrading property, low density, and low price. Natural fiber’s thermal properties and flexural properties are less than conventional fiber. This work deals with the changes in the thermal properties and mechanical properties of S-glass reinforced with a sodium hydroxide-treated pineapple leaf (PALF) and banana stem fibers. Banana stem and pineapple leaf fibers (PALF) were used at various volume fractions, i.e., 30%, 40%, and 50%, and various fiber lengths of 20 cm, 30 cm, and 40 cm with S-glass, and their effects on the thermal and mechanical properties were studied, and their optimum values were found. It was evidenced that increasing the fiber volume and fiber length enhanced the flexural and thermal properties up to 40% of the fiber volume, and started to decrease at 50% of the fiber volume. The fiber length provides an affirmative effect on the flexural properties and a pessimistic effect on the thermal properties. The PALF S-glass combination of 40% fiber load and 40 cm fiber length provides maximum flexural strength, flexural modulus, storage modulus, and lowest loss modulus based on hybrid Taguchi grey relational optimization techniques. PALF S-glass hybrid composite has been found to have 7.80%, 3.44%, 1.17% higher flexural strength, flexural modulus, and loss modulus, respectively, and 15.74% lower storage modulus compared to banana S-glass hybrid composite.

“…In recent times, there has been an exponential rise in processing capacity, which is being complemented with improved algorithms. Using such methods in conducting analytical analyses, several researchers in various disciplines have met advanced design criteria [43][44][45]. These modeling and optimization strategies have addressed the issues in physical complexity that are commonly faced in scientific and engineering research [44,46].…”

Due to their low density, natural fibers have increasingly found application in the development of systems such as wind turbine blades, airplane wing spar where flexural strength is a strong criterion for material selection. Although different researchers have studied the mechanical properties of such natural fiber composites, none has focused on the optimization of the flexural strength of pineapple leaf fiber (PALF)/glass fiber (GF) reinforced epoxy hybrid composite. This study applied the Taguchi and general regression analysis method in the optimization and modeling of the flexural strength of the P x G y E z composite. Flexural strength of 144.5 MPa at an optimum development parameter of PALF at 20% volume content, GF at 20% volume content, and fiber length of 25 mm. Analysis of variance and regression analysis was also employed to describe and model the flexural behavior of the developed composite. The PALF fiber showed to have a higher contribution to the flexural strength of the material. The equation developed to model the flexural behavior of the material showed a good correlation between the simulated value and the experimental values of the flexural strength at different combinations of manufacturing parameters.

“…Computational techniques have become an important tool to model, analyze, and optimize the parameters/characteristics that affect the properties of natural FRP composites. Mulenga et al [22] reviewed various computational tools including support vector machines, decision trees, K-means, K-nearest neighbor, Naive Bayes, and artificial neural networks (ANNs). Kumar et al [23] studied the machining characteristics of natural abaca, hemp, and Mudar fibre particle-reinforced polymer composite using the ANN.…”

Existing structures require repair and strengthening owing to degradation caused by incorrect design and construction, environmental impacts, or structural upgradation to meet new seismic design standards or to correct execution problems that occurred during construction. These strengthening requirements can be satisfied by a variety of strengthening techniques. The creation of a fibre-reinforced polymer (FRP) composite system offers a new design method for the strengthening of existing structures. In this study, posttensioned beams are strengthened by using sustainable materials such as natural jute fibre-reinforced polymer (FRP) composites. The performance of these composite systems in the flexural strengthening of posttensioned beams was used to assess their effectiveness. Consequential result for longitudinal reinforcement throughout the length of the beam for flexural strengthening was evaluated. Flexural performance, crack width, ductility, and load-deflection relationship study of control beams (Scheme A) and retrofitted beams (Schemes B and C) under different wrappings were considered in the investigation. An experimental study depicts that using the full wrapping (FW) technique increases the flexural strength of PSC beams wrapped in JFRP by 23% and, by using the strip wrapping (SW) technique, the flexural strength is increased by 10%. The JFRP composite system of strengthening has shown the highest deformability index and showed that the JFRP material has enormous potential as a structural strengthening material.
