Baking Composites: Layup and Curing

Variety of methods are employed to manufacture biomedical composite components. Most of the methods have been adapted from those available for manufacturing composites for non-biomedical applications (e.g., aerospace applications)., and tweaked as required to meet design, regulatory and manufacturing requirements unique to biomedical applications. Method selection for a particular component depends on the biomaterials, design requirement and application.

The Map All Biomaterialists Should Understand

We know various material types (e.g., metals, ceramics, polymers) can be used as raw materials to develop an implant or device. We also know composites comprise of more materials. The manufacturing processes shape and assemble the materials into the final product. Heating and cooling techniques are routinely employed during the manufacturing process to shape and deposit the materials. These techniques generate microstructures (typically visible only under a microscope) that play an important role in defining the final product properties. During material’s thermal processing, understanding the nature of phase transformations that give rise to various microstructures is crucial for control of final product properties. Central to this understanding of phase transformation is to have a good grasp of phase diagrams or “maps” for the design of processing methods. So let us delve a little bit more into phase transformation and phase diagrams.
