Abstract
To evaluate the influence of various preparation conditions on standard Douglas-fir (Pseudotsuga menziesii) plywood gluebond specimen performance, tests were conducted on samples in wet boiled and dry states and kerfed such that opening and closing of lathe checks occurred under each conditioning method. Each factor and combination of factors had statistically significant influences on load at failure but not percent wood failure.
**********
To evaluate softwood plywood gluebond quality, small samples removed from full-size panels are prepared and tested to evaluate percent wood failure. Wood failure, expressed as a percentage of the ...
