THE IMPACT RESISTANCE OF MODIEFIED FERRO-CEMENT PANELS

The suitability of ferro-cement as a marine structural material is discussed and contrasted to other hull materials, particularly with regard to impact resistance. Established trends and findings regarding impact resistance of ferro-cement are reviewed. Mechanisms of impact failure are examined in general and in relation to materials used in this project. Experiments are performed on several configurations involving ferro-cement with laminations of fiberglass reinforced plastic and sheet rubber, as well as unmodified ferro-cement. All configurations are chosen keeping in mind that most or all of the advantages of ferro-cement are to be retained. The experiments show that vast improvements in impact resistance from a permeability viewpoint are possible, on an equal weight basis, over unmodified ferro-cement. Improvements of up to 500 per-cent are demonstrated.
