fabricforming

Fabricforming is a manufacturing process that uses flexible molds to shape materials. Unlike rigid molds, fabric molds conform to the contours of the object being formed, allowing for complex shapes and intricate details. This technique is particularly useful for creating lightweight and complex parts, especially in industries such as aerospace, automotive, and prosthetics.

The process typically involves placing a fabric membrane over a mold cavity. The material to be formed, often a liquid or pliable substance like resin or composite, is then introduced into the cavity. Pressure is applied, either externally or internally, to force the material against the fabric membrane. The fabric acts as a compliant surface, ensuring even distribution of pressure and capturing fine details of the mold. Once the material cures or solidifies, the fabric is removed, leaving behind the formed part.

Advantages of fabricforming include its ability to create parts with high strength-to-weight ratios, reduced tooling costs compared to traditional methods, and the capacity to produce organic and non-uniform shapes. It can also accommodate variations in part thickness and reduce the risk of defects like voids or delamination. The flexibility of the molds allows for easier demolding of intricate geometries. This method is an evolving area of manufacturing, with ongoing research focused on optimizing materials, pressure application, and achieving higher precision.
