Abstract

An experimental activity conducted in order to assess the impact behavior, at room and low temperature, of laminates used in the shipbuilding industry, was reported. The conditions which reproduce the impact of a hull at low temperature with a solid body suspended in the water was reproduced. A test equipment was designed and realized to reproduce the real material behaviour in water to obtain a load distribution on the entire surface of the specimen. The results were obtained impacting the laminates placed between the cilyndrical steel impactor and the bag containing water. A falling weight machine equipped with an instrumented steel impactor and a thermal chamber was adopted for the experimental tests. Laminates made by vinyl ester matrix and carbon fibres were considered during the tests, and the results in terms of impact behaviour in hostile environments were compared to what obtained at room temperature. The data obtained under a distributed load were also compared with the results of impacts at concentrated loads.
