Title

BAMBOO: FUNCTIONALLY GRADED COMPOSITE MATERIAL

Pages

  1-10

Abstract

 The BAMBOo structure can be generally viewed as a Functionally Graded composite material constituted by long and aligned cellulose fibres embedded in a lignin matrix. Analysing the transversal section of a BAMBOo culm, one can observe that the fibre distribution is variable through its thickness. The non-uniform distribution of fibres prevents the direct application of equations used to model the behaviour of COMPOSITE MATERIALS, as the rule of mixtures equations for strength and modulus of elasticity. These equations assume, besides the perfect bonding between fibre and matrix, uniform distribution of the fibres in the matrix. In BAMBOo, the fibre distribution follows an organized pattern with a higher concentration of fibres on the outer surface of the culm. Establishing how this variation occurs, the basic equations from the COMPOSITE MATERIALS approach can be modified in order to model the mechanical behaviour of BAMBOo. This paper presents the meso-structure analyses of BAMBOo culms through DIGITAL IMAGE ANALYSIS. The variation of the volume fraction of the cellulose fibres across the transversal section of the BAMBOo is established. The developed methodology is successfully applied to study the volume fraction variation of fibres in two different samples of BAMBOo species Phyllostachys heterocycla pubenscens, commonly know as "Moso".
