MAKO Advanced Materials Adds Aerofin Silica and Carbon Phenolic Prepregs for Rocket Motors

MAKO Advanced Materials introduced the Aerofin P-3300S and P-3300C ablative prepregs and molding compounds for high-temperature aerospace and defense applications, the company announced on November 11, 2026. The silica and carbon phenolic systems are positioned as alternative reinforcement sourcing for solid rocket motor manufacturing, according to EIN Presswire.

Inside the Aerofin P-3300X Material Line

The Aerofin P-3300X line covers two material systems. Aerofin P-3300S combines heat-treated silica fabric reinforcements with a silica-modified phenolic resin formulation, and Aerofin P-3300C pairs heat-treated carbon reinforcements with a carbon-modified phenolic resin formulation. Both use MAKO's high-char-yield Aerofin phenolic resin formulations, which form a protective char layer during controlled thermal decomposition to limit heat transfer to underlying components.

MAKO lists rocket nozzles, solid rocket motor components, heat shields, re-entry vehicles and hypersonic platforms among the applications for the phenolic composites. The company said material selection depends on the thermal environment, component geometry, structural requirements and manufacturing process.

Both systems ship in continuous-fabric broadgoods prepreg and chopped bulk molding compound formats. Broadgoods prepregs are continuous reinforcement fabrics pre-impregnated with phenolic resin and can be used in tape wrapping nozzles and laminate fabrication. The molding compounds use half-inch chopped material squares designed to flow and consolidate under heat and pressure during compression molding. Finished components may undergo additional machining depending on part specifications and processing conditions.

On sourcing, MAKO said the silica phenolic system uses heat-treated silica fabrics obtained through newer supply channels, while the carbon phenolic system includes heat-treated carbon reinforcements sourced through both established and alternative pathways. The company said the approach is intended to provide additional domestic material availability and reduce reliance on constrained legacy supply channels.

"Reliable access to ablative materials is essential for manufacturers working on critical propulsion and thermal protection systems," said Matt Jones, Head of Business Development at MAKO Advanced Materials. "Through Aerofin, our focus is on providing shorter lead time silica and carbon phenolic materials that give customers more sourcing flexibility while supporting the technical requirements of their applications."

Further information on the Aerofin ablative prepregs and molding compounds is available on MAKO's prepreg product page.

Where to Find Aerofin Product Details

MAKO directs manufacturers to its company website for information on the Aerofin line and its other composite prepregs, film adhesives, specialty compounds and custom resin formulations. The company describes itself as a U.S.-based manufacturer serving aerospace, defense and industrial applications with formulation, material development, testing and domestic manufacturing capabilities.
