Research Could Spur Use of Sustainable Composite Lumber

05.09.2008
Two University of Massachusetts Amherst researchers are developing computer models to predict the strength of structural composite lumber (SCL), which could broaden the use of the sustainable material in large building projects.

Peggi Clouston, associate professor in wood mechanics, and Sanjay Arwade, assistant professor in civil and environmental engineering, are creating the computational tools with a three-year, $300,000 grant from the National Science Foundation.

According to Clouston, SCL is a building material used extensively in North America in residential construction. SCL is created by layering dried and graded wood veneers or strands with waterproof adhesive to form long rectangular beams and other structural members.

SCL manufacturers want to make as strong a composite with the cheapest wood possible, such as waste wood or weed species, she says, but new products must be tested in a laboratory to determine their strength. That process can be time-consuming and costly, says Clouston.

Clouston and Arwade’s research is aimed at producing a quick and inexpensive analytical method that will accelerate the development of less costly or stronger wood products that could be used in major non-residential building projects such as shopping centers or schools, she says.

“By making the predictive capability widely available, this project marks a first step in advancing the practice of wood design to a state comparable to that of steel and concrete,” says Clouston. “Building products manufacturers and engineers will have a great interest in this.”

Along with economic advantages, she says, SCL offers significant environmental benefits because wood is renewable, recyclable, biodegradable and sustainable. “It takes less energy and creates less pollution to transform trees into wood products than it does to manufacture steel, concrete or plastic products,” says Clouston.

According to the researchers, the work will lay a scientific foundation for investigations into other wood products such as glue-laminated timber or plywood. Graduate-level course modules on wood composite modeling are part of their integrated plan for research and learning.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
