Abstract
Lightweight and strong components having any desired shape, form, or geometry may be manufactured using thermally expanding mandrels by the processes described herein. A thermally expanding mandrel may be formed from an expanding material composition including thermally expanding particles, e.g., micronized rubber particles, and water-soluble binder material, e.g., gypsum plaster. Component material may be applied to the mandrel, and the mandrel may be inserted into a molding tool. Upon application of heat to the mandrel, the mandrel may expand, and compress and cure the component material into a component within the molding tool. Following formation of the component, the mandrel may be washed out of the component, e.g., using pressurized water, and the expanding material composition may be recycled and/or reused.
