Instron (Norwood, Mass.) offers the Dynatup 9250 impact testing machine, designed to measure energy absorption and related impact properties of composites, polymers, metals and resulting final components. It is specifically designed for use in aerospace, automotive, biomedical and finished product applications. The drop tower uses Instron’s Impulse computer control system, which captures, plots and analyzes the impact event, enabling the user to determine incipient damage, ductile-to-brittle transition point, maximum load and total absorbed energy. The device also can test materials in extreme temperatures and is available with a specimen feeder option for high-throughput testing.
