DEFLECTION PERFORMANCE OF MEDIUM DENSITY FIBERBOARD AND PARTICLEBOARD SHELVES JOINED ABS, PLA, AND WOOD-PLA FILAMENT PINS
Abstract
This study determined the deflection performance of wooden shelves force by using different material types. In addition, the pins used as fasteners of the shelves are made of ABS, PLA and WOOD-PLA filament material. The independent variables consisted of material type, pins fila-ment material, and filament fill, and the dependent variable was determined as deflection value. Medium density fiberboard (MDF) and particleboard (PB), both melamine faced, were used as two different material types. The study was based on the BS EN 16122 (2012) standard. However, the TS EN 9215 (2005) standard was followed to reveal the deformations that occur in the shelves after increasing loads. The factors affecting deflection value and the interaction between them were investigated by multivariate analysis of variance. The results showed that the material type, filament fill and filament material type were significant. The adequacy of models was evaluated by the R-square (R²) and Adjusted R-square (Adj-R2) values. The results for these val-ues were 96.1 % and 94.2 %, respectively.
