Abstract

In the Hungarian forests 600,000m3 of beech is cut annually. Unfortunately, only 60% of the harvested timber has a healthy red heart. The timber market either does not accept red heart or takes it only at a very low price. In order to utilize red heart more effectively, examinations were made on its macroscopic, physical, and mechanical characteristics. Relying upon these findings, the types of products that could be produced were determined and a technological model of red heart beech was developed. Comparative material testing showed that physical characteristics, durability and abrasive resistance of timber with a healthy red heart are more favourable than those of the normal white wood. Steaming of the timber makes the colour more homogeneous. When determining processing chain besides the separation of white wood and red heart, the partition of juvenile wood is also important. Accordingly, 3 types of products are to be specified: a) white wood; b) good-quality red heart; c) products of juv enile wood, mostly made of red heart.
