Three Methods for Analyzing Charring Behavior in CLT Panels Exposed to ASTM E119 Standard Fire Test Condition

Creator:: Hong, Seung hyun
Abstract:: This thesis consists of three manuscripts related to the methodology of evaluating charring behavior in cross laminated lumber panel specimens subjected to fire performance tests on cross-laminated lumber panel specimens. The topic of the first manuscript is the measurement of char rates of unprotected CLT layups fabricated with ponderosa pine...

Fluorescence Spectrometry to Quantify Percent Wood Failure in Adhesive Bonds

Creator:: Rueppel, Talbot B.
Abstract:: Structural engineered wood manufacturers need a quantitative measurement technique to determine the ratio of wood to adhesive failure in their shear specimens. Visual estimation of percent wood failure has long stood as an extremely subjective quality control approach according to ASTM D5266 – Standard Practice for Estimating the Percentage of...

Elucidating the Mechanism of CNF Reinforcement in Wood Adhesives and Composites

Creator:: Munoz Torres, Maria A.
Abstract:: In the search to improve and incorporate nano and renewable materials into urea-formaldehyde (UF), several researchers have incorporated cellulose nano fibrillated (CNF) into the adhesive. This study aimed to find an optimal way of incorporating CNF into UF and understand how CNF interacts with and changes the properties of the...

Defining Project‐Specific Custom CLT Grade Utilizing Low‐Value Ponderosa Pine Lumber from Logs Harvested in SW Oregon and Northern California Forest Restoration Programs

Creator:: Jahedi, Sina
Abstract:: Restoration programs effectively prevent or mitigate wildfires and pest outbreaks in the forest lands. The most common approach is to selectively harvest smaller and dead trees in order to preserve larger and superior trees. Ponderosa pine, Pinus ponderosa, (PP) lumber is one of the common species harvested from restoration programs...

Analysis of adhesive atomization on composite bond performance

Creator:: Willard, Dylan T.
Abstract:: Spraying of liquid adhesive onto wood surfaces has shown to be a highly effective and efficient method of application across many different wood-based composite industries. However, the dynamics of spraying are extremely variable and distribution can be affected by liquid properties (rheology, molecular weight distribution, and temperature), application parameters (disk...

Forests on the Move: Forest Inventories and Wood Anatomy from the Fragmented Forests of Guairá, Paraguarí, and Central, Paraguay

Creator:: Cervantes, Andrew G.
Abstract:: Forest composition in Paraguay has been in a state of change for the past half century due to land management practices, forest fragmentation, and deforestation for agriculture. How these factors affect dendrological diversity and wood anatomy in Paraguay is not well understood. This thesis documents Paraguayan forest composition on the...

Effects of Temperature and Moisture Content on Bonding Performance of Mass Plywood Panels

Creator:: Wind, Matthias C.
Abstract:: As a new product patented by Freres Lumber Company in 2018, little information exists for manu-facturing procedures of mass plywood panels (MPP). At first glance, MPP may appear to be ply-wood, laminated veneer lumber (LVL), or similar to conventional cross-laminated timber (CLT). Often manufacturers, as well as users, of MPP...
