DEVELOPMENT OF SEAWATER RESISTANT OF FRP EPOXY COMPOSITES

Abstract

Abstract: Benefiting from good mechanical properties, excellent corrosion resistance and light weight property, glass fiber reinforced polymer composites are recommended for use in marine infrastructures. However, the poor marine environment accelerates the corrosion of composites, which can easily result in the deterioration of material properties. In this paper, the seawater (SW) ageing of epoxy/glass fiber composites(GFRP) was summarized. The changes of water absorption and mechanical properties with immersion time were discussed, and the influence factors and corrosion mechanism of seawater immersion corrosion were analyzed. The results show that temperatures, preparation crafts, water species and fiber volume fraction of GFRP have great influence on the water absorption and mechanical properties of GFRP. Water and chemical substances, such as acids, bases, salts, and microbes contained in seawater, will lead to the physical and chemical degradation of GFRP. In addition, water creates a dual mechanism of positive effect by plasticizing and swelling and negative structural damage caused by corrosion, which leads to the fluctuation of mechanical properties of GFRP in the early stage of aging.

Key words: GFRP, water absorption, seawater aging, mechanical property, interfacial debond
