Composite core and sprayable barrier coats

 

Composite Technologies International’s (Anniston, Ala., U.S.) AmeriCore is said to be a first-of-its-kind core made of 100% composite materials. AmeriCore has minimal resin demand and chemically bonds with the laminate, forming a single component that makes delamination a non-issue. AmeriCore is also compatible with most resin systems and is easy to use. AmeriCore is scored and scrimmed and conforms to curved surfaces, reducing the possibility of air pockets and weak spots. With optimal shear strength and stiffness, AmeriCore is said to be an ideal replacement for other core reinforcements within composite laminates. AmeriCore is resistant to fire and smoke, is said to have high screw retention, absorbs little to no water and will not decompose. Using AmeriCore is also said to provide an economic benefit by eliminating time-consuming steps in the manufacturing process while also improving the quality and consistency of finished goods. It can add quick, consistent bulk thickness and help reduce the variation in a chopper gun process.

Composite Technologies International has also recently announced Fiber Shield, a sprayable barrier coat and print blocker. Fiber Shield is said to be a user-friendly product that enhances the cosmetics of gel coat surfaces, improves thermal-shock resistance and helps reduce manufacturing times. Designed for both hand-laid and infused laminates, Fiber Shield minimizes air entrapment and reduces or eliminates the need for finishing rework. Fiber Shield also extends the life of molds by protecting against laminate heat and shrinkage. For components that are frequently exposed to water such as boats and pools, Fiber Shield’s 100% vinyl-ester-based version provides osmotic-blister resistance.
