Abstract

In this research, a new gypsum composite material, reinforced with Carloduvica Palmata plant fiber, is developed for use as prefabricated panels in interior spaces. An experimental methodological design with a quantitative approach is used, since the study variables will be manipulated until the desired physical characteristics are achieved. The first step is to obtain the natural fiber from local suppliers, then a treatment consisting of: washing, chemical purification, bleaching and crushing. The fibers are classified according to their length and diameter, and then specimens are made with different compositions of gypsum and organic material to perform flexural and compression tests in a specialized laboratory. The analysis with the specimens revealed that the L2 fiber (12 x 1 mm) with a density of 3% in the mixture obtained the best compression and flexural results, demonstrating that both the 36 mm and 1 mm elongated fibers are of lower resistance. Similarly, the panels were fabricated with this material and were found to have superior characteristics compared to a conventional gypsum panel. Also, the physical appearance of the reinforced panel does not differ from conventional panels, so it may represent a possible substitute. Conclusion: the use of biodegradable materials in the manufacture of construction materials represents a more environmentally friendly process to reduce the risk of environmental pollution and greater energy efficiency.
