EVALUATION OF THE MECHANICAL AND SURFACE PROPERTIES OF BRAZILIAN FILM FACED PLYWOOD PANELS

Abstract

Film faced plywood panels represent an important solution for the civil construction industry, especially for use as concrete forms, due to their strength, durability, and the possibilite of reuse. Considering the relevance of this material and the need to ensure the quality of products available on the market, this study aimed to evaluate the performance of film faced plywood panels produced by four Brazilian industries, focusing on their compliance with standards requirements for application in civil construction. The tests were conducted in accordance with ABNT NBR 17002 (density and static bending), ABNT ISO 12466 (glue line shear strength), and ABNT NBR 17001 (phenolic film evaluation). The results demonstrated that all panels met the minimum required standards, showing satisfactory performance across the different tests. The variations observed among the industries highlight the influence of factors such as panel density, veneer composition, and manufacturing parameters. It is concluded that the panels evaluated are technically suitable for use in civil construction, provided they are correctly applied, and can contribute to greater efficiency, reuse, and performance of concrete forms.
