The DIC method is applied to measure the mechanical properties of the Phenolic resion foam material. Porosity foam material is a good heat insulation material. The Phenolic resin foam material has low flammability, low smoke and low toxicity. It has been extensively applied in many public safety related industries and products. But, the mechanical behavior of Phenolic resin foam material is brittleness, tensile strength is low and adhesion force is not good. Therefore, this material is used as bare filler or boarded as sandwich material for outer wall or roof of building. The mechanical properties of these kind materials should be known about under consideration for installing safety and economic effects. The bare material of Phenolic resin foam material is used to test the tensile strength, compressive strength and bending strength. The developed "digital imagine correlation method" is used to measure the strain field to ensure the difference between this material and traditional construction materials. The results show that the digital image correlation method can be successfully applied to measure the mechanical properties of Phenolic resin foam material.
