A truck body manufacturer in southern Germany lost €220,000 on a single bad density call last year. They specified 60 kg/m³ pvc foam core for refrigerated van panels chasing a 12% weight reduction over their previous build. Six months into service, those panels started delaminating. The low-density foam had soaked 35% more resin during layup…
A truck body manufacturer in Texas committed to 1,200 square meters of custom 8mm aluminum honeycomb panels from a new supplier in 2025. First container passed incoming inspection with zero rejections. Second container arrived with face sheet thickness swings of 0.3mm between panels — three times the ±0.1mm tolerance their assembly fixtures required. The production…
A Midwest RV OEM called us last January after their entire 2026 fifth-wheel line failed thermal certification in Alaska field testing. The spec called for R-11 whole-wall performance. Their supplier’s data sheet claimed R-5.6 per inch on the polyiso core. Sounded right. But nobody calculated the thermal bridging through the aluminum framing — actual whole-wall…
We see three or four warranty disasters a year traceable back to one engineering decision: the pp vs aluminum honeycomb core selection. Last year, a European ambulance OEM scrapped 40 vehicle bodies because their aluminum honeycomb panels delaminated from carbon fiber skins. Galvanic corrosion ate the bond lines. Nobody caught the materials conflict during spec…
