Introduction to the test method of PEEK (polyetheretherketone) tensile elastic modulus

The tensile modulus is the ratio of stress to strain (i.e. distance) generated by a sample under tension within the elastic range. It is one of the indicators that characterize the tensile properties of a material. The larger the tensile modulus, the greater the rigidity and the higher the strength. It is also called Young’s modulus and is represented by E. The tensile modulus is calculated as follows: E = Δf / Δh Among them, Δf represents the change in stress between two points per unit cross-sectional area, and Δh represents the change in strain between two points. The methods currently used to accurately measure the tensile elastic modulus include the extensometer method and the strain gauge method. ⑴ Extensometer…
