Design and Development of False Ceiling Board Using Polyvinyl Acetate (PVAc) Composite Reinforced with False Banana Fibres and Filled with Sawdust

Abstract

This work deals with design and development of false ceiling board from polyvinyl-acetate (PVAc) composite reinforced with false banana fibres and filled with sawdust. The aim was to develop a light weight and good strength performance false ceiling board using raw materials that are fully biodegradable including sawdust, thus solving the problem of its disposal. The false banana fibres were characterized for its tensile strength, elongation, and moisture content since these parameters affect the composite properties. Hand lay-up method combined with compression molding followed by curing was utilised in the manufacture of the false ceiling composites. The optimum proportions of the raw materials were identified using central composite design software, and the results were 40% sawdust, 40% binder (PVAc), and 20% fibres. The mechanical properties of the developed composite board were evaluated in terms of its tensile strength, flexural strength, and compressive strength. In addition, the composite physical properties were also evaluated including its density and moisture absorption. The optimum results obtained were tensile strength of 12.54 N/mm2, compressive strength of 7.03 N/mm2, and flexural strength of 5.13 N/mm2.

Development and study of false ceiling panels using pumice and steel square mesh-case of Ethiopia

“…Polyvinyl acetate and false banana fibers were used as reinforcement along with the addition of saw dust to produce FC panels [6]. The composite of false banana fibers and sawdust ceiling board showed better performance.…”

Processing of polymer wood composite material from pine cone and the binder of phenol formaldehyde/PVAc/molasses and improvement of its properties

“…This decrease is explained by the dependence of the composite material properties on resin properties. Zeleke and Rotich [35] produced composite false ceiling material with sawdust, banana ber and PVAc resin in their study. Computer software was used for producing samples, and a ratio of 40% sawdust, 40% PVAc resin and 20% ber was determined as the most suitable material rates.…”
