This grade of PEEK has been tested and approved for biocompatibility as per ISO 10993 for blood and tissue contact. This carbon fiber reinforcement elevates the stiffness and strength to be many times those of plates made from unreinforced PEEK or plates with short fiber reinforcement. TECATEC PEEK MT CW50 ® black plates are based on Victrex® PEEK that is reinforced with 50% vol. There are several medical-grades of PEEK, but here are some common brand names sourced from AIP’s industry partners. Not only does it maintain continuous use up to 480☏ (250☌), it’s also an attractive precision plastic for components used in the medical field for the following reasons: PEEK fulfills the requirements for biocompatibility under FDA and ISO 10993 guidelines. Additionally, medical OEMs will use PEEK in precision medical devices that require stability in high heat and chemical environments. It has also become a material choice for implants and instruments over other medical-grade plastics and metals. 63–94 (2018)īarbara, A.M.: Fabrication methods and costs for thermoset and thermoplastic composite processing for aerospace applications.Medical grade PEEK has gained traction as a leading medical technology for its advanced properties and unique compatibility with human tissue and fluids.

Nadlene, R., et al.: Chapter 15 - out-of-autoclave as a sustainable composites manufacturing process for aerospace applications. The morphological tests were made in order to verify if there was porosity in the composite, due to the manufacturing process, and verify if the layers were well compacted. DSC tests were carried out to analyze the Tg (glass transition temperature) in order to verify if there was still some polymerization process to finish and verify the combination of parameters that was proposed in the work plan. The laminate was manufactured via hot compression molding instead the usual process for this material, as autoclave. For this study, it was used a prepreg made with epoxy-carbon fiber, that is used for autoclave process, however, it has been used for OOA process, to see if it is possible to reach similar or better results compared with the samples from autoclave. OOA is widely used due to be faster and cheaper process in relation to autoclave, beyond to be possible to manufacture complex shaped parts and reduce secondary stages.
The hot compressing molding is a process considered out-of-autoclave (OOA) cured process. Instead, hot compression molding is a fast process, that does not require a long process time and the quality of the part is similar to the parts made in autoclave. The manufacturing process for composite via autoclave has an expensive cost and take a long cycle time until the piece is ready and it is possible to open the autoclave.
