| 中文摘要 | the use of interlaminar fracture tests to measure the delamination resistance of unidirectional composite laminates is now widespread. however, because of the frequent occurrence of fiber bridging and multiple cracking during the tests, it leads to artificially high values of delamination resistance, which will not represent the behavior of the laminates. initiation fracture from the crack starter, on the other hand, does not involve bridging, and should be more representative of the delamination resistance of the composite laminates. since there is some uncertainty involved in determining the initiation value of delamination resistance in mode i tests in the literature, a power law of the form g(ic) = a.delta alpha(b) (where g(ic) is mode i interlaminar fracture toughness and delta alpha is delamination growth) is presented in this paper to determine initiation value of mode i interlaminar fracture toughness. it is found that initiation values of the mode i interlaminar fracture toughness, g(ic)(ini), can be defined as the g(ic) value at which 1 mm of delamination from the crack starter has occurred. examples of initiation values determined by this method are given for both carbon fiber reinforced thermoplastic and thermosetting polymers. |
