Abstract
Natural fibers have an important role in research aimed at renewable resources, because its natural characteristics reduce the impact on the ecosystem when discarded. In this context, this article aims to determine the termal properties of sugar cane fiber as it is a fiber abundantly found in the country, for its ecological characteristics and also for easy handling. For that, measurements were made using the hot wire method with dry fiber and wet fiber. The method is relatively simple, being a transient heating process with well defined boundary and initial conditions. The result of the termal conductivity of the sugar cane fiber was approximately 0.116 W/(m·K) for wet sample and 0.0996 W/(m·K) for dry sample. The process uncertainty generated a value below 0.5% relative error, proving that the fiber has a good performance for heat treatment.
