Abstract

Densification is a well-known method for improving the mechanical properties of wood. In the present study, unmodified and furfurylated wood samples were densified and submitted to cyclic water storage tests and cyclic alternating climate tests. Swelling coefficients and spring-back data were determined for the evaluation of the quality of densification. The study shows that results depend on the test method applied. Simple water storage tests do not reflect the behavior of densified wood in the high humidity range. The spring-back data of unmodified samples are more influenced by the testing method than those of the furfurylated ones.

Keywords: compression wood; densification; furfurylated wood; furfuryl alcohol; modified wood; set recovery; spring-back

The research project was financially supported by the Federal Ministry of Economics and Technology of Germany. This project (grant reference 16735 BR) of the research community International Association for Technical Issues was processed by the AiF (Working Committee of Industrial Research Communities) as funding of the Industrial Community Research. The preparation of the samples and the microscopic images was conducted at the Institute of Material Science. The authors would like to thank their colleagues in this institution for the generous support.
