2021-01-18 Monday - Researching Coremat

 This blog post is a placeholder as I gather links to information about coremat: 


  • https://www.carbonfiberglass.com/Foam-Core/coremat 
    • "Coremat is a nonwoven polyester that contains microspheres and is used primrily as a bulker mat or liner in composite laminates  that have been  made using a hand lay-up or  Vacuum Infusion as the means of production. Coremat should always be fully saturated with resin. The microspheres contained  in the Coremat will prevent excessive resin up-take."
    • "Coremat Xi By Lantor sets the standard for bulker mats. Resin consumption for coremat is approximately 600 grams per of mm thickness. It also utilizes a resin indicating compound that changes color showing that resin has been applied to the Coremat."
    • "Coremat Xi is very soft and pliable when it is wet is suitable for use within complicated shapes or molds."

    • "Lantor coremat is a traditional coremat or bulking mat used to quickly build up thickness in basic fibreglass moulds and components. The mat has a relatively high resin uptake but still lower than solid laminate, allowing thickness to be built up with less resin and less weight. Standard coremat is not suitable for resin infusion, vacuum bagging or RTM/lite."

    • "Coremat® 4mm 39.37". Coremat is a random laid, shredded polyester material, which is soft in nature and conforms well. This materials is used for creating bulk in a laminate as well as controlling print. Using this material as a core is a cheaper alternative to solid fiber parts and the use of the core will add rigidity"
