Fabric-cement composites developed using the pultrusion production process have demonstrated impressive tensile and flexural properties. AR Glass and PE fabric reinforced composites exhibit strain-hardening behavior in addition to tensile strength in the range of 20 to 25 MPa and strain capacity of the order of 2 to 5%. Impact properties were investigated under three point bending conditions using an instrumented drop weight system. Test parameters include the fabric type, specimen orientation, and drop height of hammer. Preliminary results indicate that for the same drop height, the vertical type (beam) specimens are stiffer; however, they have a lower ultimate deflection and higher load carrying capacity than the horizontal (plate type) specimens. By increasing the impact energy beyond 5 Joules, the impact strength of the horizontal specimens made with glass fabrics sharply decreased, while there was no incremental change in the impact strength of the vertical specimens. Results are compared with the static flexural tests conducted under closed loop deflection controlled tests.
