## Description

- description: A new approach using a modified double cantilever beam test was proposed
    for evaluating the mode Ⅰ-governed critical energy release rate representative
    of unidirectional composite rods, defined here as the mode Ⅰ critical separation
    energy, 〖SE〗_IC. This approach was used to characterize basalt fiber reinforced
    polypropylene rods. The relation between load and displacement is obtained from
    loading-holding-unloading tests, where apparent crack length—defined as the straight-line
    distance between the loading axis and crack tip—is measured at the end of holding
    time of each cycle; the start of crack propagation is confirmed by in-situ digital
    microscope observation. Scanning electron microscope observation of fracture surface
    reveals matrix crack growth and fiber-matrix interfacial debonding. The linear
    relation between apparent crack length and cube root of compliance is obtained,
    and the 〖SE〗_IC calculated by the compliance method is 1.5 ± 0.5 kJ/m2.
