Physico-mechanical properties of plywood bonded by nano cupric oxide (CuO) modified pf resins against subterranean termites

Nano CuO and alkane surfactant modified phenol Formaldehyde (PF) resins were applied to manufacture plywood, and physical and mechanical properties, such as shear strength, tensile property, modulus of rupture (MOR), modulus of elasticity (MOE), as well as termite resistance were evaluated. The resu...
