Bending properties

The bilinear form Bg -, ) describing the bending properties of the shell is as follows ... 

Plywood has essentiahy equal stability in both panel directions and is almost as stable as the parent wood in the direction of the wood grain. Strength properties in bending are roughly proportional in each panel direction to the amount of wood in those layers closest to the surface which are parahel to the wood grain direction. Thus as the number of phes increases, these bending properties become more equalized in both panel directions.

In some textile production laboratories single reference standards or a simple set of hand standards with different hand values is used. This set of standards is produced from the same fabric as the one being evaluated by applying the same softener at incremental concentrations. If the softener is used in combination with other finishes, the concentration of the other fmishes must be held constant. Relatively simple methods to evaluate only the bending properties of fabric (flex rigidity) are the cantilever method and a similar device called Softometer, which are described in Chapter 4 on hand building. 

The most comprehensive but most expensive method of objective hand evaluation was developed by Kawabata and co-workers " and is called KES-F (Kawabata Evaluation System-Fabrics). It consists of several different measuring instruments, for example for tensile and shear properties (KES-Fl), bending properties (KES-F2), compressibility (KES-F3), surface (KES-F4) and thermal (KES-F7) properties. The measured parameters and the area weight are normalised and correlated to the subjective handle scores. From this correlation, for every hand evaluation a transformation equation is developed, resulting in a primary... 

In three-layer flakeboards based on five softwood and hardwood species of 4, 10, and 18% moisture content, with press temperature of 177 °C, 6-min press time, and 3% isocyanate binder, the results showed that moisture content of wood was the most important variable at 18% moisture level, IB and bonding properties were lowest. Species of wood influenced strongly the bonding efficiency. In almost all cases the bending properties were the key characteristic of the panel performance. Southern pine produced the boards with lowest IB (81-116 psi), and red oak gave the highest IB values (98-213 psi) (J95).

Bending properties of boards made from Particle-c were lower than board-1 and board-2 as shown in Figure 5. This may have been caused by the low quality of particle shape and by the steam treatment of chips before hammer milling.
