Compression test for paper materials are much more difficult to perform than tension test. Its main reason is based on low buckling resistance of paper materials. So far many test methods have been tried to provide consistent and precise experimental uniaxial compression test data. Most of test methods use lateral support to prevent buckling phenomena in global and local levels. Ideally the lateral forces are minimum during the test. However there always exists extra loading in an unixal compression stage in order to obtain resonable data. This experimental works have been carried out ot investigate on the development of lateral force-free uniaxial compression test method for paper materials. The objective of this study is to investigate on optimum conditions for making paper-aluminum-paper panel that will be used in the lateral force-free uniaxial compression test.
