Raziskovanje fizikalnih in mehanskih lastnosti tropskih vrst lesa : zaključno poročilo

Možina, Ivan (project manager), Torelli, Niko (author), Uršič, Janez (other)

Pričujoče poročilo opisuje testne postopke in prinaša rezultate raziskave fizikalnih in mehanskih lastnosti, naravne odpornosti proti glivam ter vsebnost silikatov za 28 tropskih listavcev, ki pred tem še niso bili tehnološko preiskani. Poskusna drevesa so bila v 1970ih letih izbrana v nedotaknjenem gozdu jugozahodnega dela Centralno afriške republike, takrat Centralnoafriškega cesarstva. Vsi testi so bili izvedeni v skladu z mednarodno sprejetimi standardi za male, gladko obdelane vzorce brez napak. Podana je diskusija o uporabnosti preiskanih lesnih vrst.

Abstract

The present report describes the test procedures and presents the results of a study on the physical and mechanical properties, natural decay resistance and silica content of 28 tropical hardwoods which ere not tested prior to that time. The test trees were selected in the 1970ies in the virgin forests of the southwest Central African Republic, then the Central African Empire. All tests were carried out according to internationally accepted standards for small, smooth, defect-free samples. The potential end-use of the wood species tested is discussed.
