An improved method to measure the bulk compression behavior of fiber mass is studied.
Compression experiments are carried out with Instron Tensile Tester equipped with apparatus designed and made in our laboratory which consists of a compression stand and a support table. By the aid of this apparatus the effective area of each sample mass is kept constant during a compression test.
In order to secure the reproductibility of tests the method of sample preparation is investigated.
