EXTRACTION METHOD OF INTER-LAMINA SHEAR MODULUS AND EXTRACTION APPARATUS OF INTER-LAMINA SHEAR MODULUS USING THEREBY

摘要

The present invention relates to an extraction method of an inter-lamina shear modulus and to an extraction apparatus of an inter-lamina shear modulus using the same. More specifically, the present invention relates to a method for additionally extracting the inter-lamina shear modulus of an anisotropic material such as a composite material via a test for finding bending shear strength, which is classified into a short beam shear test, and to an extraction apparatus of an inter-lamina shear modulus using the same. The extraction method of an inter-lamina shear modulus according to the present invention comprises the steps of: measuring displacement caused by the weight of a material to be tested via a short beam shear (SBS) test (S1); and extracting the inter-lamina shear modulus of the material from the displacement data caused by weight (S2).
