Rigid fiber-reinforced polymers lack the necessary ductility for complex shaping after initial curing. Overcoming this limitation allows for post-production reshaping and secondary processing of high-strength materials.

Poor adhesion between heterogeneous composite layers or porous membranes leads to structural delamination. Overcoming this limitation ensures mechanical integrity and leak-proof seals in multi-material assemblies.

Non-uniform distribution of foamable material during injection leads to structural weaknesses and dimensional inaccuracies in composite panels. Achieving precise density control ensures predictable mechanical performance and structural integrity.
