  1. Evaluating weather factors and material response during outdoor exposure to determine accelerated test protocols for predicting service life

    To develop service life prediction methods for the study of sealants, a fully instrumented weather station was installed at an outdoor test site near Madison, WI. Temperature, relative humidiy, rainfall, ultraviolet (UV) radiation at 18 wavelengths, and wind speed and direction are being continuously measured and stored. The weather data can be integrated over time to...

  2. Evaluation of materials during outdoor testing using a computer-controlled test apparatus

    Ultraviolet radiation, moisture, heat, and cyclic fatigue are some of the stressors that cause materials to degrade outdoors. Considerable research has addressed the effects of ultraviolet radiation and moisture on the rate of this degradation. An often overlooked stressor on materials, during outdoor testing, is the cyclic fatigue. Cyclic fatigue is caused by self-...

  3. Nanotechnology opportunities in residential and non-residential construction

    Over 1.9 × 106 housing units are constructed in the United States in 2004. On a volume basis, wood products comprise almost 80% of all materials used in residential housing. It is estimated that over 7 × 109 m3 of lumber have gone into structures in the United States over the last century. Half of the wood products now used in construction are engineered wood...

  4. Advanced wood- and bio-composites : enhanced performance and sustainability

    Use of wood-based-composites technology to create value-added commodities and traditional construction materials is generally accepted worldwide. Engineered wood- and lignocellulosic-composite technologies allow users to add considerable value to a diverse number of wood- and lignocellulosic feedstocks including small-diameter timber, fast plantation-grown timber,...
