Abstract
In this paper, new compressed-wood manufacturing process 'Roll press method' was proposed. In order to manufacture compressed-wood column or long sheet, application of rolling mill for compression process had been studied, although there were still two problems for application of rolling mill. One was occurrence of cracks or delaminations that were arisen from local deformation along roll. And another one was dimension recovery. We designed devices to prevent these problems and developed new compressed-wood manufacturing process 'Roll press method'. Roll press method enable manufacturing compressed-wood without crack or delamination, and dimension recovery. We manufactured compressed-wood by roll press method and did static bending test. Bending test result showed positive correlation between bending strength and compression ratio. These results mean effectiveness of roll press method and denote possibility for manufacturing compressed-wood column or long sheet.
