BioResources, 2019 The inclusion of old newspaper as reinforcement in composites promotes the use of environmentally friendly materials, reduces landfilling, decreases chemical treatments to bleach the recycled paper, and provides alternatives to glass fiber. While there are studies on the tensile strength and stiffness of old newspaper reinforced materials, there is a ...

Flexural modulus identification of thin polymer sheets
IOP Conference Series: Materials Science and Engineering, 2011 The method of determination of the flexural Young's modulus is based on a solution to the problem of compression of a thin-walled cylindrical specimen by two parallel planes (TWCS method). This method was employed to calculate the flexural modulus for PET polymer compositions.
