Hull Material Evaluation for Navy 44 Sail Training Vessel.

摘要

Material characterization tests were performed at the US Naval Academy to identify a toughened laminate for the new Navy 44-foot sail training vessels. After preliminary analysis using classical lamination theory, four different cores, five laminates and seven resin systems were tested in UV exposure, four-point bending, lateral panel pressure, and simulated bow impact. Results showed substantial improvements in strength, toughness, cost and weight were possible over the existing laminate, with the lightest acceptable laminate yielding a weight savings equivalent to 3.5% of the vessel's displacement.
