Calibration and testing for the evaluation of plywood glue bond performance in accordance with en 314-1 and en 314-2

Deliverables

The project has developed a comprehensive performance database for plywood products, which consist of: -Various combinations of species and glues -Evaluated from various EU research institutes -Evaluated based on visual test pieces -Evaluated based on scanning images The performance data is fundamental information for modelling and designing plywood products. The performance data has successfully been used as a calibrated database for database programme development � PlyBond in the PLYWOOD project. The target user groups for the database will be: -Plywood manufacturers, -Testing laboratories, -Certification bodies, -Standardisation committees.
PlyBond is a database for the storage of information gathered during the glue bond performance test, and is effectively split into two sections. The first section is for factory production control and the information gathered is sufficient to show compliance to all the standards associated with the glue bond performance test. PlyBond will also give reports relating to the glue bond performance test. The second section is a training module, where each individual operator can train and store their training record on the database. The training consists of either black and white schematic images and colour images of test pieces. The black and white images are designed to give an operator training in basic area assessment techniques and the colour test pieces are for more realistic practice. The system also gives a report on the operator�s progress over time. Each component of the whole system has successfully been verified internally and externally and is fully operational and marketable. This quality management system demonstrates as most efficient and user-friendly tool for internal factory control, external control by an accredited laboratory. The target user groups for the system will be - Plywood manufacturers, - Testing laboratories, - Certification bodies.
PlyWoodFail is software for the automatic inspection of plywood shear samples for their wood fibre failure percentage (WFF) A shear sample (normally 10 pairs of 25 mm x 25 mm test pieces) must be mounted into a sample holder and placed on an office scanner. PlyWoodFail then scans an image of the sample, evaluates it by image analysis and gives an estimation of the WFF for each test pieces. Each component of the whole system has successfully been verified internally and externally and is fully operational and marketable. This quality management system demonstrates as most efficient and user-friendly tool for accurate evaluation of wood fibre failure for internal factory control, external control by an accredited laboratory. The target user groups for the system will be - Plywood manufacturers, - Testing laboratories, - Certification bodies.
