Odun katkılı PLA malzemelerinin yapışma dayanımlarının incelenmesi

In this study, plates were produced from wood added polylactic acid (PLA) based materials using 3D printers, which is one of the additive manufacturing methods. After applying mechanical abrasion (sanding), which is one of the surface preparation methods, to the surfaces of the produced plates, the adhesive bonding process was carried out. Adhesive joints were made using the additive-free and additive formula of 3 different commercial adhesives (Araldite 2015, Loctite 9466, and PVA wood glue). In commercial adhesives, 5% hazelnut shell powder in 45 µm dimensions was added and the bonds were joined by forming an additive adhesive formula. The obtained joints were subjected to the tensile test and their mechanical properties were examined. The experiments were repeated for plates cut from Scotch pine wood (Pinus Sylvestris Lipsky) with the same adhesives and the values found were compared with the results of the joints made with wood added PLA. With the results obtained, the strengths of pure (plain) and filled (modified) joints were evaluated. It has been observed that Loctite 9466 adhesive provides the highest shear strength in joining wood added PLA and Scotch pine materials with adhesive. The aim of this study is to investigate the adhesion performance of PLA composites, a high-tech material, when used in the furniture and wood sector.
