This study was undertaken to determine whether Douglas-fir (Pseudotsuga
menziesii (Mirb.) Franco) veneer could be platen-dried and then
sucessfully glued into two-ply parallel-laminated panels.
A range of veneer thicknesses, platen temperatures and final dry
moisture contents were examined. Thicknesses included were nominal
0.1, 0.2, 0.3 and 0.4 inches; platen temperatures...
The main objective of this study was to determine appropriate
accelerated aging methods for exterior plywood made with Southeast
Asian hardwood face veneers. A secondary objective of this study
was to determine the durability of exterior plywood made with keruing
(12 Dipterocarpus spp.).
To reach these objectives I made plywood...
The quality and cost of wood particle composites are substantially
determined by how the adhesive that bonds the composite is
distributed on the particles. Distribution of the adhesive is controlled
by the method of application. Currently the adhesive is applied by
spraying it onto the particles. It was hypothesized that...
Difficulties have been encountered in gluing some Southeast
Asian woods using phenolic resin. Extractives in veneers from the
trade groups yellow, white, and red meranti (Shorea, Parashorea,
and Pentacme spp. ), keruing (Dipterocarpus spp. ), and kapur
(Dryobalanops spp. ) were suspected to be able to modify resin cure
and...
Deposition of the Middle Devonian part of the Denay Limestone
and Bay State Dolomite in the northern Antelope Range and Fish
Creek Range, respectively, took place on and in front of a carbonate
platform with a lime sand shoal at the shelf edge. In the Givetian part
of the Denay...
Time-dependent crack growth mechanisms in Alloy 617 at 800°C in air were studied using compact tension samples machined in the L-T direction, cracked at temperature using an induction furnace and servo-hydraulic load frame. The application of different loading waveforms, including triangular, hold time, and sustained loading, were studied with relation...
