Core materials are the backbone of high-performance composites. They increase stiffness, reduce weight, and improve durability, making them essential across aerospace, marine, automotive, and construction industries.
In this guide, you’ll learn:
Core materials are lightweight layers placed between composite skins (laminates) to form a sandwich structure. This design dramatically boosts structural performance without adding significant weight.
Choosing the right core starts with understanding your options:
Foam cores are among the most widely used due to their versatility and performance.
Popular options include:
PVC Foam: High compressive strength and moisture resistance
Best for marine, wind energy, and aerospace applications
PET Foam: Recyclable and sustainable with good thermal insulation
Ideal for environmentally conscious projects
PU Foam: Excellent energy absorption
Common in automotive and industrial components
Honeycomb structures provide an exceptional strength-to-weight ratio, making them ideal for high-performance applications.
Aluminum Honeycomb: Lightweight, strong, corrosion-resistant
Used in aerospace and transport
Nomex Honeycomb: Fire-resistant and lightweight
Perfect for aircraft interiors
Carbon Fibre Honeycomb: Ultra-stiff and high-performance
Used in advanced engineering applications
A natural core solution with excellent strength-to-weight properties.
