Earlier published engineering notes
ImpacGard™ is a patent pending composite facing that absorbs impact energy to reduce the risk of major structural damage, and minimize the potential for hazardous debris.
Patent pending ImpacGard™ standard products can be used in an environment between -40°C to 100°C.
Custom products can be formulated to increase maximum temperature up to 220°C without sacrificing performance.</span></p> <p class="style200"><span class="style191">ImpacGard™ Fx</span> is a front guard for dramatic improvement in the impact resistance of composites, which are prone to fracturing on impact.
It will absorb impact energy at the surface and is not thermally sensitive.

glass transition and melt temperatures of the matrix) and the forming takes place as the dies close.
This allows the part to be removed from dies after only a few minutes, while also allowing sufficient crystallinity to develop.
AFP followed by stamp forming was used to make stringers and frames for the RL4 demo article.
Co-Fusion is a patented thermoplastic composite processing method that combines skin consolidation and welding of faying stiffening elements into a single bag molding process [5].
The system utilizes a heated tool and breather/insulation under the bag in an ambient temperature room or autoclave to create a thermal gradient through the thickness whereby the skin and faying flanges melt but the protruding portion does not.
e recent NASA-led efforts to fill in the TPC material property database by the authors and collaborators are summarized in the remainder of this section.
2 It is noted that bonding is theoretically a process localized to the adherend interface while in practice an elevated temperature cure cycle is often applied by heating the region or entire part, which can introduce additional challenges.
