UNESP -BRAZIL BAMBOO PROJECT : MECHANICAL CHARACTERISTICS OF THE GLUED LAMINATED BAMBOO BAMBOO PROJECT 1- Priorities species introduction and cultivation
START : 1990 OBJECTIVES : BAMBOO RESEARCH AND DIVULGATION STEPS : 1-Priorities species introduction and cultivation 2 - Culms management and production 3 - Physical and Mechanical characterization 4 - Culms processing 5 - Products/Design Dendrocalamus giganteus CULMSAGE CONTROLL CULMS PROCESSING Transversal Longitudinal cutting. cutting
Four face shaper Nodes removal STRIPS POSITION Brazilian wood standard (NBR 7190)
-parallel compressive test : 5 x 5 x 15 cm -simple bending test : 5 x 5 x 115 cm -parallel tensile test: 5 x 0,7 x 42 cm PARALLEL COMPRESSIVE TEST SIMPLE BENDING TEST PARALLEL TENSILE TEST Elasticity modulus (GPa)
AVERAGE VALUES Strength (MPa) Elasticity modulus (GPa) U (%) Tensile ft0 = 143.7 Et0 = 20.6 11.2 Simple bending ff = 98.9 Ef = 13.6 11.3 Compressive fc0 = 65.5 Ec0 = 18.1 (density = g/cm3) SOME DEVELOPED PRODUCTS CONCLUSIONS The main conclusion:glued laminated bamboo has good mechanical characteristics to be used in bamboo products confection and in this way it can contribute to avoid native wood cutting GRATEFULNESS Thank you
