Abstract: In this study, several types of Gigantochloa scortechinii bamboo strips were used as fillers in an unsaturated polyester matrix and characterized in term of their tensile and flexural properties. The strips were formed with the culm fiber composite with inner-to-outer layer thicknesses of 1.5 mm, 2.0 mm, and 2.5 mm. The laminated bamboo strips composites were developed using the hand lay-up technique. The analysis was carried out using a 2-factor, 3-level design of experiment (DOE) and an analysis of variance (ANOVA) to determine how the layer strip and the thickness of the bamboo affected the mechanical properties of the composites. It was proven that both the bamboo layer and the thickness demonstrated significantly different results in terms of the tensile and flexural performance. The overall results indicated that the middle layer of the laminated composite exhibited the highest tensile and flexural strength
