Production of Fiberboard Using Wood Fiber and Tetra Pak® Material and Evaluation of Some Physical and Mechanical Properties

Abstract

Composite boards were produced using Tetra Pak ground material and wood fiber, and the effects of the mixture ratio on the properties of the boards were determined. The main purpose of the study was to obtain a fiber board by bonding Tetra Pak material with wood fiber using phenol formaldehyde adhesive. For this purpose, waste Tetra Pak boxes were collected after domestic use and ground in a high-speed grinding machine. The obtained ground material (Tetra Pak material) was mixed with the wood fiber used in fiberboard production at different ratios of Tetra Pak material (0%, 33%, 66%, and 100%). These mixtures were glued using phenol formaldehyde. Each mixture was first formed into a sheet and then pressed in a hot press using a metal mold. After pressing, the physical (density, water absorption, and thickness swelling) and mechanical properties (modulus of rupture, modulus of elasticity, internal bond, and hardness) were determined. According to the data obtained, increasing the proportion of Tetra Pak material in the produced panels improved their physical properties while decreasing their mechanical properties. The modulus of rupture and modulus of elasticity values for group 1 and group 4 decreased from 32.1 to 10.4 N/mm² and from 2777 to 1019 N/mm², respectively.
