Particleboard can be commonly produced by flat-pressing and extrusion methods. The elastic properties of the flat-pressed particleboard have been studied a lot, but the extruded particleboard has not had much attention. Six elastic properties of two commercial extruded tubular particleboards with different solid density were measured by a three-point bending test and electric resistance gages method. The elastic modulus in the extruded direction of the tubular particleboard is only one-tenth of the other two directions. The extruded tubular particleboard can not only be regarded as an orthotropic material but also a transverse surface isotropic material. The isotropic plane is the transverse section of the extruded particleboard which is different from the flat-pressed particle with the length–width plane as the isotropic plane. The checking of the data we measured demonstrated suitability and rationality.
