Abstract

Machine strength grading has traditionally been focussed on softwoods. With the introduction of many 'new' (hard)wood species from around the world on the market, especially from sustainable managed forests, there is a need for strength grading of 'unknown' species and assign them into strength classes. In this project, over 1500 beams from 30 different species covering the whole range of strength, stiffness and density profiles have been tested using both non-destructive and destructive testing techniques. The dataset was used to develop a species independent strength grading model in order to classify timber without the need of extensive and expensive laboratory testing. Optimisation of the yield of a hardwood species with visual grading is not possible, but using non-destructive measurements hardwood timber can be assigned to higher strength classes improving the yield.
