RESEARCH ON THE BEHAVIOUR OF MDF DOOR FRAMES AFTER IMMERSION IN WATER

Abstract

The paper presents the results of the researchwork performed on the behaviour of the door framesmade of laminated MDF (cherry and walnut foil) onimmersion in water. The MDF boards were purchasedfrom two different suppliers. The immersion wasmade untill the critical limit was reached, when thedimensional characteristics of the frame came out ofthe field of tolerances. The dimensionalmeasurements, together with the mass weights wereperformed at different times, finaly achieving differentcritical limits for the two types of materials. The finalconclusion of the research showed that, after a periodof 24 hours of immersion in water, both materialshave suffered major dimensional changes thataffected the use of the door frame. The paperprovides information on the relative and absolutevariations of sizes and mass, including percentagechanges.
