CAMX 2021 exhibit preview: Pyromeral Systems

Pyromeral Systems (Barbery, France) develops and manufactures advanced materials and composite parts for applications requiring resistance to high temperatures. The company’s ceramic matrix composite (CMC) technology, based on innovative inorganic matrices, are designed for continuous exposure to thermomechanical environments up to 1,000°C.

PyroXide is an oxide-CMC material based on Pyromeral’s proprietary matrix, reinforced with Nextel 610 Alumina fibers. PyroXide composites present mechanical properties combined to low density; they reportedly show a flexural strength of 300 MPa, a modulus equals to 70 GPa, an interlaminar shear strength beyond 15 MPa with a macroscopic density of 2.5 g/cm³. Unlike standard oxide-CMCs, Pyromeral says, PyroXide material shows a microstructure with a controlled microporosity, including an almost total absence of macroporosities and microcracks linked to shrinkage of thermal treatment.

PyroXide also presents radio frequency properties. For example, it has an Epsilon value of 5.0 in an 8-18 GHz  range at ambient temperature. Malleability and easy handling of PyroXide prepregs allow for the manufacture of varying thickness and complex geometry composite parts using layup. Large-scale prototypes (more than 3 m wingspan) can allegedly be produced in one shot, displaying aerospace surface quality and interesting mechanical properties. Due to these properties, and also the high temperature resistance typical of oxide-CMC, this technology can be found in the field of defense and in the development of high-speed vehicles.
