Resumo: | ||||||||
Composite boatbuilding methods used nowadays represent several risks to worker s health. Resins, hardeners and varnishes liberate toxic organic vapors in the curing process that can take up to 7 days. The present work tried in a practical approach to adapt innovative materials with standard building methods in the research for an alternative productive process that can mitigate workers exposure to toxic substances. At first, we focused on understanding the properties of natural fibers and castor oil polyurethane resins and their potential possibilities on the development of composite materials, as well as understanding the state-of-art of correlated researches at LILD (living design free investigation laboratory). Afterwards, we developed vacuum bagged sandwich composite panels with the studied materials, which finally were used to build of a small sailing craft. Several issues were brought to debate during workshop cooperative work. Establishing connection with conventional boatbuilding methods showed the research was about technique
instead of material resistance. We believe that the practical daily construction needs are as much important as the material resistance itself, especially if you aim to work directly on the building process. With that in mind we went for available materials and simple low cost technologies in the search for a reliable boat.
Several composite materials techniques were tested due to the boat s project characteristics (an outrigger sailing canoe): bonding, hand lay-up, vacuum bagging etc. Results were promising, shown on a robust yet light and graceful vessel.
