The paper reports on the impact performance evaluation of glass fibre reinforced cement (GRC) materials. The paper includes a review of the principles of impact testing methodology and a proposal for a new test method consisting of a drop weight instrumented impact on plate specimens. The significance of impact test data is discussed with regard to the parasitic effects on impact load versus time records. An application of digital filtering treatment provided the load-displacement characteristics reflecting the specimen response alone. The following impact features of the GRC elements were determined: the maximum impact load, the energy absorbed up to the maximum load and the energy absorbed up to total failure. The energy absorption capability of GRC plates was studied as a function of plate thickness and impact velocity. A comparison of the impact data and the reference quasi-static tests yielded a ratio of impact-to-static energy absorption of 1·7–1·8 for the GRC elements considered. Keywords:
