The fracture behavior of TPX (poly-4-methyl-1-pentene) polymer was studied using compact tension (CT) and single-edge-notch bending (SENB) specimens. Effects of crosshead rate and environmental temperature (-40°C to 160°C) on fracture behavior were investigated. Fractographic analyses were conducted after fracture tests using scanning electron microscopy (SEM). The results showed that the fracture behavior of the TPX polymer was highly dependent on crosshead rate and temperature. Unstable-stable transition of crack growth and stiky-slip behavior were observed for both low and high crosshead rates when the environmental temperature was increased.
