Product Description

High Performance Non Woven Core Mat for Vacuum Infusion Wind Blade Manufacturing
 

Product Description

Coremat is a non-woven polyester that contains microspheres and is used build laminate bulk and block print-through in composite laminates . Produced in a variety of widths and thicknesses, core mat is also known as a laminate bulker or a core fabric. It is used to build laminate thickness (increasing stiffness) and to isolate laminate shrinkage from the cosmetic gel coat surface. In applications requiring good cosmetics, core mat is used to improve surface quality; particularly with darker, more revealing gel coats. Popular in the marine and recreational vehicle industries where surface finish is critical, core mat wets out quickly and is conformable to fit mold contours.
Coremat  is very soft and pliable when it is wet is suitable for use within complicated shapes or molds.

The cost effective solution for open mould processes
Is used as core material and/or print blocker
Is a polyester nonwoven and compatible with all regular
types of resins, including Polyester, Vinylester, Phenolic and Epoxy
Is suitable for hand lay-up and spray-up processes

 

Application

Marine: hulls, decks and structures of boats and yachts
Transportation: parts and panels of cars, trailers and trucks
Mass transit: interior and exterior of trains, light rail and buses
Leisure: kayaks, surfboards, pools and tubs   
Wind energy.

FAQ

FAQ 1: What is non woven core mat used for in wind blade vacuum infusion?

Answer:
Non woven core mat is used as a lightweight core and resin distribution layer in wind turbine blade manufacturing. It helps improve resin flow, increases laminate thickness, and enhances structural performance without significantly adding weight.
 

FAQ 2: How does non woven core mat improve resin infusion efficiency?

Answer:
The open and uniform fiber structure of non woven core mat allows fast and controlled resin flow during vacuum infusion. This reduces dry spots, shortens infusion time, and ensures consistent fiber wet-out across large wind blade structures.
 

FAQ 3: Is non woven core mat compatible with different resin systems?

Answer:
Yes. High performance non woven core mats are compatible with epoxy, polyester, and vinyl ester resin systems commonly used in wind blade manufacturing. They maintain stability during infusion and curing processes.
 

FAQ 4: Can non woven core mat replace traditional core materials in wind blades?

Answer:
Non woven core mat is often used to supplement or partially replace traditional core materials such as foam or balsa in specific blade areas. It is particularly effective in shear webs, bonding areas, and thickness build-up zones where improved resin flow and conformability are required.
 

FAQ 5: How should non woven core mat be stored and handled?

Answer:
Non woven core mat should be stored in a dry, clean environment, protected from moisture and contamination. It is recommended to keep the material sealed before use to maintain consistent infusion performance.
 

Customer Reviews

 

• The non-woven core mat is excellent for vacuum infusion in wind blade manufacturing. It allows smooth resin flow and helps produce strong, lightweight blades with minimal voids.

• I used this high-performance mat for wind turbine blade prototypes, and it performed perfectly. The material is consistent, easy to cut and lay, and improves overall infusion efficiency.

• This non-woven core mat is very reliable for large composite structures. It provides uniform thickness, excellent resin permeability, and helps achieve high-quality finished parts every time.
