Boat Hull Blisters: Repair Techniques and Long Term Effects on Hull Degradation

Abstract

The report documents the research and experimental work undertaken to further explore the causes and nature of osmotic blisters, experiments performed in techniques to reduce the formation of the blisters and repair of damage caused by the formation of blisters. The work is contained in the following sections: Introduction; Causes and Nature of Boat Hull Blisters; Water Solubles - Air Inhibition Studies; Water Solubles Associated with Glass Reinforcements; Swelling Stresses Produced by Diffusion; Long Term Damage by Water Absorption; Effects of Gel Coat on Leaching of Water Soluble Material from Laminates; The X- Layer, a Diffusional Interphase; Blister Initiation Time Distribution; Blistering of Shop Prepared Samples; Effect of Coatings on Water Diffusion Profiles; Drying of Hull Materials During Repair; Types of Repair Coatings Investigated; Performance of Repair Coatings; Evaluation of Repair Techniques; Recommendations for Repair of Blistered Boats; Summary of Conclusion; References. Keywords: Hulls; Marine FRP (Filament Reinforced Plastic).
