Abstract

Properties of light particle boards manufactured using Abies grandis (grand fir).

Abstract

Light wood composite products like honeycomb sandwich boards are manufactured in expensive production steps. It is necessary to first separately produce the planking and the middle layer. In a further step, the three compounds have to be put together to one composite product. On the other hand, it is possible to conventionally produce wood-based panels with light density such as the grand fir, using the best available technology. Three industrial trials were made for the production of three shifted particle boards. The results of these investigations have shown that it is possible to reduce the density of the panels manifestly without losses in regards to the mechanical-technological properties. Comparative studies using spruce and pine clearly substantiated the advantage of grand fir for practicable reduction in panel density.
