Honeycomb cores feature a cellular structure that provides high stiffness and strength relative to weight. Common honeycomb materials include aramid paper and aluminum, with properties that vary based on cell size, density, thickness, and material composition.
These materials are used in aerospace sandwich panels, aircraft interiors, fairings, and other lightweight structures where weight efficiency and mechanical performance are important.
Our honeycomb core offerings through Pacific Coast Composites include materials listed to BMS 8-124 Type 5, Class 4, Grade 3, in 0.5-inch and 1-inch thicknesses.
Structural foam cores provide lightweight support in sandwich composite construction. Common materials include PVC, PET, and PMI foams, each offering different combinations of mechanical properties, temperature resistance, and processing characteristics.
These materials are used in aerospace, UAV, marine, and industrial composite applications where structural efficiency, dimensional stability, and compatibility with manufacturing processes are important considerations.How do I select a core filling material for honeycomb composite structures?
Honeycomb and structural foam cores are used in lightweight sandwich panel construction for aircraft interiors, partitions, and secondary structural components. By separating the composite face sheets, core materials help increase bending stiffness without significantly increasing overall panel weight.
Material selection depends on structural requirements, weight targets, fire performance specifications, and compatibility with the intended laminate system.
Composite core materials support sandwich structures used in fairings, control surfaces, and other aerospace components where stiffness-to-weight performance is critical.
Honeycomb and structural foam cores offer different mechanical and processing characteristics, allowing engineers to evaluate materials based on loading requirements, component geometry, operating conditions, and manufacturing methods.
Lightweight sandwich structures are used in UAV and advanced air mobility applications where minimizing structural weight is an important design consideration.
Core materials help provide stiffness and structural support in composite panels, fairings, and other components while accommodating application-specific performance requirements.
Structural foam cores are commonly used in marine and industrial sandwich composite applications, including hulls, decks, panels, and lightweight structural assemblies.
Core selection considers mechanical loading, moisture exposure, dimensional stability, and compatibility with the intended resin system and manufacturing process.
Selecting the appropriate composite core material requires evaluating structural performance, manufacturing requirements, and compatibility with the complete sandwich construction.
Important considerations include:
Honeycomb and structural foam cores may be incorporated into sandwich structures using compatible prepregs, structural adhesive films, and resin systems. Processing methods vary based on core composition, laminate design, and cure requirements.
