Laboratory analysis on the mechanical properties of spiny (Kawayan Tinik) bamboo layers Ma. Louise Margaret A. Ramos and Ma. Doreen E. Candelaria. pages 51-66 color illustrations Bamboo has been introduced as a possible alternative to some construction materials nowadays. Its potential use in the field of engineering, however, is still not widely practiced due to insufficient engineering knowledge on the material's properties and characteristics. Although there are researchers and studies proving its advantages, it is still not enough to say that bamboo can sustain and provide the strength and capacity required of common structures. In line with this, a more detailed analysis was made to observe the layered structure of the bamboo, particularly the species of Kawayan Tinik. It is the main intent of this research to provide the necessary experiments to determine the tensile strength of dried bamboo samples. The test includes tensile strength parallel to fibers with samples taken at internodes only. Throughout the experiment, methods suggested by the International Organization for Standardization (ISO) were followed. The specimens were tested using a universal testing machine, with a rate of loading set to 0.6 mm/min. It was then observed from the results of these experiments that dried bamboo samples recorded high layered tensile strengths, as high as 600 MPa. Likewise, along the culm's length and across its cross section, higher tensile strength was observed at the top part and its outer layers. Overall, the top part recorded the highest tensile strength per layer, with its outer layers having tensile strength as high as 600 MPa. The recorded tensile strength of its middle and inner layers, on the other hand, were approximately 450 MPa and 180 MPa, respectively. From this variation in tensile strength across the cross section, it may concluded that an increase in tensile strength may be observed towards the outer periphery of the bamboo. It is highly recommended to conduct experimental investigations on the layered compressive strength properties as well. Also available in print. Lab analysis. Mechanical properties.
