Description
This premium non-woven composite core material is the most affordable and simplest core option used in advanced composites. It is compatible with all standard resin systems and is designed to build up thickness in basic fibreglass moulds and components. This versatile core material is suitable for open mould processes including hand lay-up (HLU) and spray-up (SU) but is not recommended for resin infusion, vacuum bagging, or resin transfer moulding (RTM).
With a relatively high resin uptake, this core material allows for thickness to be built up using less resin and resulting in lower weight compared to solid laminate. Composed of a polyester-based non-woven fleece containing closed microspheres, it does not absorb resin, making the core considerably lighter than glass reinforced plastic (GRP). This enhances stiffness without the extensive use of costly materials, providing an economical solution for various applications.
The core material can be easily integrated into any composite part, increasing stiffness while reducing weight without requiring special tools or extensive knowledge. Typical applications include marine hulls and decks, car panels and parts, industrial cladding, as well as leisure equipment such as kayaks, surfboards, pools, and tubs.
