SikaAxson US (Madison Heights, Michigan) is introducing ProInfusion epoxy infusion system, which features a choice of four hardeners: three for room temperature and one for high-temperature applications. It enables the mixing and matching of the hardeners to tailor reactivity and Tg to the needs of the application. Uniform mixing ratio (all 3:1, by volume) reportedly allows easy blending of hardeners for a pot life tailored to the part being produced and extends the system's usable temperature range. Designed for production of composite structures by infusion methods, ProInfusion offers good temperature cure development, high clarity, low viscosity/exotherm and shrinkage, and excellent mechanical properties. ProInfusion is also suitable for vacuum-assisted resin transfer molding (VARTM) projects and various marine applications.

When humans do finally travel to Mars, they will have to be well protected from a less-than-hospitable environment. The suit designed to do the job is already in development at NASA, and it relies heavily on composites.
