“…Furthermore, from previous study, the specific tensile strength of banana, sisal and okra fibres composites increased with increasing volume fraction of fibre linearly up to the volume fraction of 20.4% [17]; additionally, the tensile strength of bagasse fibre composites increased from 16.5 to 23.5 MPa, as the fibre content increased from 20 to 65(wt %) [14]. Motaleb studied the influence of alkaline treatment on mechanical properties of pineapple and jute fabric reinforced polyester resin composites.…”

The influence of fillers loading rate on the tensile behaviours (tensile strength, Young Modulus, tensile energy, tensile strain and Stress at LOP) of reinforced epoxy composites were investigated in this research. Both filler materials (OBPS and SD) where treated with 5(w/v)% Sodium hydroxide solution for 1 hour at ambient temperature of 27±3°C. The composite samples were prepared with five different volume (10, 15, 20, 25 and 30 vol%) of OBPS and SD in the ratio of 1:1, using the hand lay-up method. All the composite samples were prepared and tested according to ASTM standards, using the Universal Testing Machine. Results from this present research showed that the fillers loading had significant (P ≤ 0.05) effect on all the tensile behaviors investigated. In addition, the results showed that all the five tensile behaviours of the samples increased gradually with increase in fillers loading. The tensile strain increased by 53.18%, as the fillers loading increased from 10% to 30 vol.%.in addition the tensile strength increased from 7.86 to 27.47 MPa, while the Young modulus increased from 668.4 to 1235.93 MPa. Results obtained from this study can be helpful in the production of composite boards for industrial applications.

“…Actually, in recent years the use of natural fibers for masonry retrofitting has become a new trend to improve the constructions sustainability. Codispoti et al (2015) have studied mechanical properties of Natural FRPs made from natural fibers like Jute, Hemp, Flex and Sisal, whereas, (Srinivasababu et al, 2009) have studied the okra, sisal and banana fiber reinforced polyester.…”

Old masonry buildings represent the largest part of traditional constructions. Generally, they are both seismically vulnerable and thermally dispersive. Therefore, the need for seismic and thermal retrofitting aimed at reducing their vulnerability and environmental impact has motivated research efforts towards sustainable retrofitting solutions. This study presents a literature review of the approaches currently available for masonry retrofitting. Specifically, it highlights the use of fiber in textile form i.e., Textile Reinforcement Mortar (TRM), as Fiber Reinforced Polymer (FRP) and natural fibers (animal and plant sources) to masonry retrofitting. In addition, specific attention is devoted to the integrated (structural and thermal) fiber-based integrated retrofitting techniques that are becoming very important in the last years.

“…Subsequent to this, a number of investigations have been conducted on the utilization of okra fiber‐reinforced composites, which have exhibited considerable potential. Noteworthy examples include the effect of fiber content% of okra/PVA composites as reported by Khan et al, 34 the tensile characterization of okra/polyester composites as demonstrated by Srinivasababu et al, 35 the exploration of thermo‐mechanical and morphological properties of okra/starch composites as conducted by Guleria et al, 36 the investigation of okra/urea formaldehyde composites as presented by Khan et al, 37 the examination of okra/tamarind kernel/epoxy composites as reported by Sivakumar et al, 38 while Ramesh et al 39 studied the fatigue and dynamic mechanical properties of okra/aluminum 2024‐T3 foil/epoxy composites. Recent studies have focused on various aspects of okra fiber, including its extraction and surface modification using environmentally friendly methods reported by Kocak et al, 40 among the other investigations Khan et al 41 have explored the effects of chemical treatments and degumming methods on the fiber, Khan et al 42 also analyzed the impact of alkalization on biologically degummed fiber.…”

Contemporary researchers are directing attention towards enhancing the structural integrity of biodegradable matrices, such as polylactic acid (PLA), through the incorporation of plant fibers. The utilization of novel fibers is becoming more prevalent to achieve the specific demands of composite applications, particularly in the automotive and packaging fields. Woven fabrics are commonly favored for reinforcing composites due to their elevated specific strength and dimensional stability. In pursuit of this context, we have developed a unique woven fabric using 100% okra fiber and utilized it in the production of PLA biocomposites. This approach was made due to the unexplored potential of okra woven fabric in the field of composite manufacturing. To optimize the performance of the composites, three distinct weight proportions of okra woven fabric (OWF) were chosen, including 20%, 30%, and 40%. The obtained composites were mechanically, morphologically, and thermally characterized. The manufactured composite's maximum tensile and thermal property was attained by adding 20% OWF to the PLA. Scanning electron microscopy analysis revealed that 20% OWF composite possessed superior fiber‐matrix adhesion, improving all properties' efficacy. The overall findings reveal that the OWF/PLA composites are promising as a green material for applications in the automotive and packaging industries.Highlights A novel class of composite has been created using 100% okra woven fabric. The composite with 20% fabric content showed the best mechanical properties. Thermal properties of composites are also optimized using 20% fabric content. SEM confirms the strong fiber‐matrix bonding of 20% OWF/PLA composites. The composites are suitable for automotive and packaging applications.
