Recently, indentation method has been developed to determine the elastic and plastic deformation properties of engineering materials. In this report, the elastic modulus of a composite material which is made of biodegradable polymer "Selgreen" and carbon fiber is determined by using the indentation method. In the method, obtained Young's modulus of a composite plastic depends on an indenter diameter, indentation depth and holding time at the peak load. Comparing the obtained results with the results by the compression test, it was found that these conditions should be selected to be 2.0mm, 0.5mm and 20s, respectively. Also, it is found that the indentation test is very useful and reliable in determining the elastic stiffness of a time dependent polymer composite.
