BENDING STRENGTH PROPERTIES OF SCARF JOINTED CORE VENEER PLYWOOD
AFTER Several studies from the plywood factories manufacturing departments , the strength properties of scarf joint veneer core lay-up for the manufacture of plywood for restoration purposes. Particularly, it was examined the bending strength (modulus of rupture) of scarf jointed laboratory specimens that were connected across the grain. Different cutting angles and glues types were investigated. From these results, it can be concluded that core veneer can be utilized with end to end scarf joints for the production of Plywood . End wood veneer grain connections at different inclined planes show different strength. The cutting angle seems to be the most resistant scarf jointed with the use of the different glue.
Bending strength – MOR of the longitudinally glued at various jointing cutting angles corev eneer with scarf joints.
Based on several studies and manufacutring experiences , the following conclusions could be drawn for plywood core veneer joint types :
• Bending strength – MOR of the tested specimens fluctuated .
• Specimens with cutting angles decide the core veneer scarf joints affection .
• Modulus of rupture of the glued specimens affected more or less by the section orientation and the type of loading. Generally, specimens in radial loading and vertical section, seem to be more resistant than the specimens in tangential loading and horizontal section.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our article infringes on your rights and interests, please email us in time and we will delete it at the first time.
