Mechanical Properties of low-value lumber from small-diameter timber used in the core of hybrid cross laminated timber (CLT) 3- and 5 layer panels

Wednesday, May 3, 2017 11:00 AM - 12:00 PM

Small-diameter logs (4”- 6”at the small end) harvested off of U.S. Department of Agriculture land, as part of the forest restoration program, is currently used primarily for wood chips, pulp, or biomass. The addition of a valued-added product, such as CLT, to the utilization scheme, would ideally offer an improved offset of forest restoration operation costs compared to the existing markets for this material. The objective of this study was to assess the mechanical and economic feasibility of utilization of this timber in the core layer(s) of CLT panels. The approach is to incorporate the forest restoration material harvested in Eastern Oregon into cores of 3- and 5-layer structural panels and assess the technical viability by determination of adhesive bond integrity and benchmark engineering properties (MOE and MOR) following the CLT product standard test protocol (ANSI/APA PRG320).

Conceptual framework of the project and some mechanical test results will be presented. This presentation is in collaboration with Brent Lawrence on the utilization of low-value lumber from small-diameter timber harvested from forest restoration programs and used in hybrid CLT core layers.

 

Christina is pursuing a Master’s in Wood Science and Engineering to compliment her Bachelor’s degree within the same field.  Expected defense date is July 2017.
