Enhance Epoxy's performance with
Reinforcing FibersIt makes sense to use epoxy (rather than polyester) when working with high-performance reinforcing fibers. WEST SYSTEM Epoxy will cure fully at room temperature and doesn't require a lot of special equipment. This has made epoxy a favorite choice of both professional and casual builders of all kinds of high-performance composites. For more about the role of reinforcing fabrics and epoxy in composite laminates, read James R. Watson's Fiberglass Reinforced Composites in Epoxyworks magazine.
Determining Epoxy Laminate ThicknessTo determine the number of fabric layers required to achieve a specific laminate thickness, divided the thickness desired by the single-layer thickness of the tape or fabric you intend to use.
|Product||Fabric Weight||Single Layer Thickness*|
|740 Glass Fabric||4 oz||.008"|
|742 Glass Fabric||6 oz||.010"|
|729, 731, 732, 733 Glass Tape||9 oz||.017"|
|745 Glass Fabric||10 oz||.016"|
|727, 737 Biaxial Fabric||17 oz||.035"|
|738 Biaxial Fabric with Mat||23.9 oz||.042"|
Estimating Epoxy Coverage for Fabric Application
Below is an estimation of how much epoxy is needed to wet out 1 sq. ft. of fiberglass cloth and apply two fill coats.
|Fabric Product Number||Fabric Weight Per Yard*||Mixed Epoxy Needed|
|740 Glass Fabric||4 oz||1.4 fl. oz.|
|742 Glass Fabric||6 oz||1.61 fl. oz.|
|729, 731, 732, 733 Glass Tapes||9 oz||1.94 fl. oz.|
