Vinyl Ester

Radomes Glass Kevlar Epoxy Vinyl Ester:Assorted Randomes
FRP is commonly used in radome manufacturing due to its favorable dielectric properties, excellent strength to weight ratio, impact and corrosion resistance, relatively low tooling cost and ability to be molded into complex shapes.
The 3’-0" long radome shown at the right are manufactured using vinyl ester resin with Kevlar aramid reinforcement. Divinycil PVC closed cell foam core is also incorporated into the laminate to minimize weight of the part. These radomes are contact molded on machined metal molds to exacting tolerances.
Radomes are manufactured in a wide range of geometries, from long tubes to flat dishes, and almost every shape in between. Some additional examples, contact molded and resin transfer molded (RTM) are shown below. Materials of construction typically include Mil-Spec grades of polyester, vinyl ester or epoxy resins with fiberglass or aramid reinforcement.
