摘要：
A large number of impact tests have been carried out on woven-roving and chopped-strand-mat glass reinforced, hand laid-up polyester laminates of different thicknesses and weights. Deflection, force, absorbed energy and damaged area results for these tests have been presented and compared, and the failure modes described. A simple analysis assuming shear-dominated deflection gave good correlation with the experimental data. Prediction of the damaged area proved to be more difficult, although some correlation was seen. Further investigation into the nature of the damage is required. (C) 1999 Elsevier Science Ltd. All rights reserved.
