Composites made from unsaturated polyester and vinyl ester resins are used in the construction of tanks, boats, swimming pools, baffles, pipe, and other reinforced composites. Many of these composites are designed on a strength safety factor of 5-10. Long-term studies done are 1-3 years in duration and projected out to 10-50 years. Field use of the designed composites can range from 10 to 50 years. This paper represents data on the retention of a variety of physical properties after 10 and 15 years of constant water immersion. The panels were tested shortly after they were removed from the water bath and thoroughly dried, to look at the changes in properties during this long-term exposure on the composites and if the cross-linked polymers were being degraded during exposure. The discussions include the flexural strength, flexural modulus, and Izod impact strength.
