Abstract
In this study, we prepared composite test specimens from Eucalyptus chip particles of sizes 0.5 mm, 1 mm, and 2 mm combined with Euphorbia abyssinica fluid at an 80:20 mass ratio. We produced the particleboard under a compression load of 150 KN and kept it in the compression machine for thirty minutes inside the mold. After removing it from the machine, we secured it with C-clamps for twenty-four hours. We covered the inner side of the mold’s base and cover plates with a thin plastic layer to make it easier to remove the composite after compression. After a safe removal, we marked the specimen’s dimensions according to ASTM standards with a permanent marker. Finally, we cut the mat along the marked dimensions using a cutter machine and dried it at room temperature for three weeks. Test results showed that the bending strength, or modulus of rupture, was 37, 35, and 35 MPa with deflections of 18, 11, and 10 mm, respectively, for Eucalyptus chip particles of 2, 1, and 0.5 mm. The maximum compression strength in the tests were 23, 40, and 67 MPa, respectively. The water resistance results indicated that thickness swelling percentages were 22%, 13%, and 12% in mm, while the water absorptivity was 138%, 124%, and 108% in grams, respectively.
Keywords: Adhesives, Euphorbia abyssinica, particleboard, modulus of truss swelling, modulus of rupture
