Description

Uploaded data presents results of physical and mechanical properties of layered wood composite reinforced with carbon fiber where the MUF resins were used as a binder. Hypothesis of the study assumes that addition of carbon fibers to wood-layer panels bonded with MUF resin improves mechanical and physical properties of the panels and that orientation of CF in the composite panels affects mechanical and physical properties of the panel. The investigation included 5 variants: PE - Parallel structure/ external system; PI - Parallel structure/ internal system; CE - Cross structure/ external system; CI - Cross structure/ internal system, and RE - Reference plywood (industrial type). The following mechanical properties of manufactured composites were tested: modulus of rapture (MOR) and modulus of elasticity (MOE) were tested based on the EN 310 standard; internal bound (IB) according to EN 319 standard; screw withdrawal strength (SH) according to EN 320 standard, and physical properties of manufactured composites: thickness swelling after 2 and 24 hours of soaking in water; water absorption after 2 and 24 hours of soaking in water. Additionally cutting resistance was tested. Each test was repeated at least 10 times. Results showed that reinforcing plywood panels with carbon fibers increased both MOR and MOE. The cutting resistance showed better results for composite panels with CF in a perpendicular orientation. Moreover, the water uptake and thickness swelling after 24 hours showed better results for fibers in the core layer, either parallel or perpendicular.
