    Abstract

    Several applications of the instrumented impact test for evaluations of polymers and fiber reinforced polymers are discussed. These include simple flex bar, falling dart, and end-use component tests. Instrumented impact testing provides a complete record of the load applied to the specimen during the entire impact event. Distinct characteristics of the load record indicate the deformation and fracture process in the specimen. Subsequent analysis permits detailed study of the various fracture modes. Total absorbed energy is simply segmented into that required for initiating failure and that for propagating the fracture. Results of the laboratory impact test can then be evaluated with respect to the specific properties of interest for the product end-use.
