The team is brainstorming innovative ways to make the building material of the future—mass timber—more versatile. But in order to do that, they have to find an adhesive and a preservative, two substances that tend to be uncooperative together when used on timber, that will work concurrently for optimal bond strength and durability.
In celebration of 110 years of research at the Forest Products Laboratory (FPL), we are revisiting blog posts that detail some of our most interesting historic people, places, and projects. Enjoy!
In the early days of developing fire-retardant treatments, researchers at the Forest Products Laboratory (FPL) investigated about 130 treatments. Combinations of chemicals were used to obtain the best performance for both fire resistance and other performance properties, such as corrosion, leaching, gluing, finishing, and cost.
There was nothing earth-shattering found—though some hypotheses were discarded and new research launching points were identified. And that’s extremely important because science, research and development are not linear. Sometimes there isn’t a “Eureka!” moment, just insatiable curiosity, grit and determination that push scientists to explore and discover the unknown.
And sometimes there’s a very human element that pushes scientific discovery—healthy human rivalry.
In the world of wood moisture science, there are very few scientists at the top. FPL’s Samuel Zelinka is one of the top scientists in his field. In Denmark, Emil Thybring, another top wood moisture researcher, is challenging Zelinka. Both are trying to puzzle out one crucial question—why wood moisture behaves the way it does in acetylated wood.
Imagine being able to look straight into a wood beam and know its structural integrity.
It’s almost like a super power, except its really just amazing science—science that Forest Products Laboratory (FPL) researchers are practicing in order to be at the forefront of investigative timber safety and restoration.
Imagine a trail dipping below a steep valley edge surrounded by lush, verdant greens. A brook chatters below and in its soft watery tones invites hikers to a moment of relaxation and communion. The breeze is soft and sweet as the leaf canopy dances in unison overhead. It is idyllic and accessible because of the wooden boardwalk solidly supporting each who visit this natural wonder.
This boardwalk and others like it can be found in many natural areas. But it is made possible by pressure-treated wood, a building material that when processed with the correct preservatives, often outlasts and outperforms durability estimates and usefulness before it can biologically deteriorate.
