By Rachael Geerts – GBI Composites Materials Engineer You’ve just finished your epoxy project and it looks great! But you don’t want the sun’s UV rays to start degrading the epoxy. So, like the smart individual you are, you look into applying a UV stable topcoat over the epoxy so your project will last for […]
By Rachael Geerts – GBI Composites Materials Engineer What is the difference between abrasion and impact? What materials hold up best against each of them? These questions often come up when talking about skid plates. Skid plates are a protective layer, typically on canoes and kayaks, that reinforces the areas of the hull most likely […]
By Rachael Geerts – GBI Composites Materials Engineer Many products, especially boats, are now being manufactured with a process called Vacuum Assisted Resin Transfer Molding (VARTM), also frequently referred to as infusion. The main topics of this article are: what infusion is, how to repair an infused part with vacuum bagging vs. infusion, and the […]
