1) The document analyzes the mechanical properties of ixtle fibers from the Agave lechuguilla plant for potential use in architectural structures. Tests were conducted on loose fibers and fibers entwined together to analyze tensile strength. 2) Samples of stabilized clay soil were prepared with and without the addition of ixtle fibers. The effect of fiber length on adhesion and cracking was examined. 3) Compression tests showed soil mixtures without fiber had strength of 12kg/cm2, while adding fiber increased strength to 18kg/cm2, indicating potential to enhance earthen building materials.
