Abstract
ABSTRACT In this study, plywood and reinforced plywood with glass fiber fabric were produced with rotary peeled poplar veneers using phenol formaldehyde adhesive. Screw and nail holding tests were conducted to obtain the characteristics of the plywood and reinforced plywood boards. One control group and three different test groups were used. The effects of glass fiber fabric on the screw direct withdrawal, screw-head pull-through, and lateral nail resistance were determined. The results of the tests indicated that the reinforced plywood’s resistances to direct withdrawal of the screw, screw-head pull-through, and lateral nail resistance were significantly higher than those of the unreinforced plywood. In addition, reinforcement of the plywood boards provided longer displacement at maximum load.
Highlights
Solid wood and wood-based composite boards are used in constructing buildings because they have some superior advantages, such as easy processability, low price, good aesthetic appearance, and light weight
Bal et al (2015) investigated some of the technological properties of poplar plywood reinforced with glass fiber fabric and reported some favorable results
The main aim of this study is to investigate the screw and nail holding performance of plywood reinforced with different combinations of glass fiber fabric
Summary
Solid wood and wood-based composite boards are used in constructing buildings because they have some superior advantages, such as easy processability, low price, good aesthetic appearance, and light weight. In addition to those positive features, these materials have some negative features, such as low loadcarrying capacity and other low mechanical properties (DEMIRKIR et al, 2013; GAFF et al, 2015) Different fibers, such as natural fibers and synthetic fibers, are used to reinforce wood-based composite boards (XU et al, 1998a; CAI, 2006; MOHEBBY et al, 2011; GÜNTEKIN and AYDIN, 2015) and load-carrying structural wooden elements (BORRI et al, 2013; BASTERRA et al, 2012). Xu et al (1998b) studied the mechanical properties of plywood reinforced by bamboo or jute and reported some positive results. Bal et al (2015) investigated some of the technological properties of poplar plywood reinforced with glass fiber fabric and reported some favorable results
