Abstract
Due to their unique characteristics, natural fiber reinforced polymer composites have recently been increasingly utilised to replace traditional materials. Fire retardant resins can increase flammability, and they have a deleterious influence on the mechanical properties of the material (Fan et al., 2020). As a result, this experiment examined the flammability of woven jute fiber reinforced with fly ash. The specimens were created by hand layup using a L9 orthogonal array and varying ratios of jute fiber, fly ash, and time for chemical fiber treatment. Vertical and horizontal flammability tests are conducted in accordance with ASTM D635 and ASTM D3801, respectively. According to the test results, the inclusion of fly ash significantly reduces flammability. In this work, 5 wt% inclusion of the jute fiber, 15 wt% addition of the fly ash, and with 10 hours, NaOH treatment produces a composite with minimum burning rates of 10.2 mm/min in horizontal UL-94 tests. To determine the link between input and output characteristics, various regression models from machine learning are used. Multilayer perception produced a stronger association in both horizontal and vertical testing, according to the models.
Highlights
Numerous plants and animals are naturally exploited to obtain fibers
Ribeiro et al investigated the flame resistance of jute fiber reinforced epoxy composites intended for tile applications and discovered that the incorporation of jute fiber had no effect on the fire resistance [17]
Flammability tests are done especially for the composites manufactured with natural fiber reinforcement, as by nature natural fibers have high burning properties when compared to manmade fibers
Summary
Numerous plants and animals are naturally exploited to obtain fibers. Apart from this, numerous synthetic fibers are manufactured and reinforced. Synthetic fibers have superior mechanical properties over natural fibers since they are manufactured for their intended use Due of their unique characteristics and abundant availability, natural fibers are frequently used as reinforcement in polymer composites. Saravanan et al and Dinesh et al discussed the challenges associated with developing composites reinforced with jute fiber using a variety of manufacturing techniques and reported on their mechanical properties. Zaman et al examined the challenges associated with developing natural fiberreinforced composites with superior mechanical characteristics and chemical and flame resistance. They used a variety of treatments on natural jute fibers to strengthen the interfaces with resins [6]. Ribeiro et al investigated the flame resistance of jute fiber reinforced epoxy composites intended for tile applications and discovered that the incorporation of jute fiber had no effect on the fire resistance [17]
