Aluminum honeycomb still dominates most spec sheets for sandwich panels. That’s changing. After 15 years in composite manufacturing, I’ve watched PP honeycomb panel applications steadily claim market share in automotive, marine, and logistics because the cost-to-performance ratio is difficult to ignore. PP honeycomb core weighs roughly 1/32 of solid aluminum, resists corrosion and chemical exposure…
Ask any fleet manager what drives their material choices, and the answer is always weight. Polypropylene honeycomb panel uses have expanded far beyond simple packaging into demanding structural roles across transportation, marine, and construction — precisely because the material delivers rigidity at roughly 1/32nd the weight of solid aluminum. Our production floor has run these…
Most procurement teams default to aluminum honeycomb for lightweight sandwich panels. They assume plastic cores can’t handle structural loads or meet fire safety requirements. That assumption is costing them money. PP honeycomb panel applications have expanded into commercial vehicle flooring, marine hull construction, and architectural partitions — and the material weighs roughly 1/32 of solid…
