20.500.12556/RUL-92879 Shear strength development of the phenol-formaldehyde adhesive bond during cure The development of the shear strength of the phenol-formaldehyde (PF) adhesive bond during curing was investigated. Five different PF adhesive mixtures and 1.1 mm thick peeled beech (Fagus sylvatica L.) veneer were used to produce lap-shear specimens, which were cured at a pressing temperature of C. Dielectric analysis (DEA) and modified ABES (automated bonding evaluation system) were used to evaluate the physical-chemical and mechanical aspects of PF adhesive cure in a miniature hot-press. The degree of cure, which was calculated from conductivity data, was dependent on pressing time and the composition of the PF adhesive. An addition of rye flour to the PF adhesive significantly postponed the curing process as determined by DEA. It was found that the adhesive bond started to develop in the last stage of the curing (vitrification), by which time most of the physical-chemical conversion of the adhesive had been completed. phenol wood shear strength DEA ABES fenol les strižna trdnost true false false Angleški jezik Angleški jezik Neznano 2017-07-06 14:19:00 2017-07-06 14:19:02 2022-08-10 01:17:33 0000-00-00 00:00:00 2009 0 0 Str. 153-166 no. 1/2 Vol. 43 2009 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*824.83 0043-7719 1662089 9151749 Jost-Sernek_WST.doc Jost-Sernek_WST.doc 1 EC5FE8329711B521D3F825E1690EFBAC abc6a9c4d67ec43482c988c545b8a0d2cd4575f17f6fb47309903db217769e8b 7356a91f-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/58029a0d-a31c-43bd-8565-17b6e0b407ca https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=101022 Biotehniška fakulteta 0 0 0
