Prepreg repair solutions for aerospace structures

HexPly® M20 Prepreg for Composite Repair

In the early 1990’s, Hexcel was asked by the newly formed Composite Aircraft Composite Repair Committee (CACRC) to develop a prepreg repair solution for Aerospace structures. Hexcel proposed an epoxy prepreg with high temperature performance from a low energy cure cycle. HexPly® M20 prepreg cures at 130°C (265°F) to form a tough, high temperature resistant fiber-reinforced composite.
Compared to wet lay-up repair systems, prepreg provides a cleaner, more efficient and controllable process.
Through the CACRC qualifications, HexPly® M20 offers a harmonized product across multiple OEM’s for airlines to purchase and stock for all their fleet repair needs.


HexPly® M20 prepreg rolls are stocked by the following companies, with AIM Altitude the only current CACRC approved supplier of M20 Kits.
