Development of Disintegrated Hybrid Cross Laminated Timber

The shift within the building industry towards more sustainable constructions leads to a rising demand for wood as a building material – mainly softwood species like spruce – to replace the energy and carbon intensive materials steel and concrete. While today, the European forests still produce enough wood in the required quality, in the future the forests will come under increasing pressure due to climate change and the rising demand. To deal with this challenge, new engineered wood products must be developed that use native, climate change resistant hardwood species like beech instead of the more vulnerable softwood species like spruce. At the same time, the overall demand for wood must be limited by raising the material efficiency. One new product that addresses both issues is disintegrated hybrid cross laminated timber (DH CLT), which is presently being developed at the TU Munich. In this work, different lay-ups of DH CLT are investigated by means of mechanical experiments, complemented by numerical analyses using the Finite Element (FE) method and analytical calculations.     «
