PMI foam cores are finding a natural home in drone manufacturing — where thin sandwich panels, dual-usage capability, and zero tolerance for excess weight define the engineering brief. Why Core Material Choices Matter More in Drones Than Anywhere Else In…
Structural foam cores have gone through decades of incremental progress. PMI chemistry changed the trajectory entirely — here’s what happened and why it matters for modern composites. Where It All Started: PVC and PET Foams For a long time, sandwich…
For decades, the composite industry relied heavily on Polyvinyl Chloride (PVC) foams as the standard core material for sandwich constructions. From wind turbine blades to boat hulls, PVC was the go-to solution due to its relatively low cost and decent…
In the high-performance world of advanced composites, carbon fiber is often hailed as the “king of materials.” Its ability to provide immense tensile strength while remaining incredibly light has revolutionized industries from Formula 1 racing to commercial aviation. However, a…
In the landscape of composite material engineering, the selection of a core material is often a trade-off between cost, weight, and performance. For decades, Polyurethane (PU) foams have been the “workhorse” of the industry due to their low cost and…
In the high-stakes world of composite manufacturing, the choice of core material is only the beginning of the journey. To truly capitalize on the benefits of advanced sandwich structures, engineers and technicians must master the nuances of processing. ROHACELL® (PMI…
The global shift toward sustainable energy and the increasing demands of the maritime sector have catalyzed a revolution in material science. As industries strive for greater efficiency, durability, and performance, traditional materials like heavy metals and standard polymers are being…
Structural foam technology doesn’t stand still. While incremental improvements to established materials continue—slightly better properties here, modest cost reductions there—genuine innovation that changes what’s possible in composite design happens rarely. ROHACRYL® represents one of those rare moments. Developed by Evonik…
Material selection in composite engineering has never been straightforward. Every project brings its own matrix of requirements—weight targets, mechanical loads, thermal environments, production volumes, budget constraints—and the “right” material emerges from navigating trade-offs that rarely resolve cleanly. For decades, engineers…
When engineers discuss structural foam cores, the conversation inevitably circles back to a fundamental tension: the desire for low weight pulling against the demand for high mechanical performance. Most foam materials force designers into uncomfortable compromises along this continuum. ROHACELL®…
