説明
Fiber waviness is one of initial defects during processing such as filament winding. The fiber waviness causes reduction of compressive strength of the composite structure. The mechanism of growing of the fiber waviness is, however, not completely clear. In the present study, a new model of generating fiber waviness is proposed. It is assumed that the local fiber micro buckling causes the fiber waviness. The micro buckling is based on the compression load caused by shrinkage of a metal jig. Three processing faults are considered as causes of this micro buckling: bonding between a metal jig and a composite (poor release), insufficient cure of the resin (non-uniform temperature) and initial deflection of fibers (poor tension during FW process). The model predicts fiber micro buckling during cooling process after cure. In the present study, to simplify the experimental conditions, prepreg sheet is adopted instead of FW process and the fiber micro buckling predicted using the model is compared to the experimental results. As a result, the new model successfuly predicts the initiation of the fiber micro buckling during cooling process.
