An ST-130 sacrificial lay-up tool and the resulting composite part

An ST-130 sacrificial lay-up tool and the resulting composite part.

Simplify the Creation of Hollow Composites

Create hollow composites faster and easier with temporary lay-up tools made from ST-130 material. ST-130 withstands autoclave operations and simplifies hollow composite construction by dissolving after cure, leaving only the finished part.

Sacrificial Tooling Material

ST-130 material is engineered and tested specifically for sacrificial tooling. It is used with a standard triangle fill pattern to optimize build speed, conserve material and promote fast dissolution. ST-130 is capable of autoclave cure, making it an optimal choice for sacrificial lay-up tools used to make hollow composite parts.
