In the context of ASAP17 we are working on developing an innovative, new technology for in-situ resin infusion and a point-initiated self-sustained curing process (frontal polymerization) of composites for space applications. Novel to our approach is that we can apply the abundant vacuum of space to the whole surface area of the composite part.
The product consists of an impermeable inner membrane, resin flow channels, arranged (e.g. braided) reinforcement fibers and an outer membrane that is permeable by gaseous elements but not the fluid resin constituents.
The possible applications of this technology are manifold and range from simple instrument booms, antennas and structural elements to larger scale space infrastructure for robotic and human exploration missions.
