Abstract
In this paper, the Linear Thermal Expansion Coefficient of Guadua angustifolia- Kunth samples was measured using the Photoacoustic (PA) technique in a heat transmission configuration and considering the thermoelastic bending as a PA signal generation mechanism in addition to the thermodiffusion ones. The obtained value of (27±7)x10-6K-1 is a reasonable value compared with that reported for similar materials such as wood.
