Flexiphene™ reinforces the fiber-matrix interface in structural and antiballistic composites — enhancing delamination resistance, interlaminar shear strength, and energy absorption. The same surfactant-free nanocarbon technology validated by NASA JPL, now engineered for impact-critical applications.

In high-performance fiber-reinforced composites, catastrophic failure rarely occurs through the fibers themselves. It happens at the fiber-matrix interface through delamination and interlaminar shear failure — the weakest link in the structure. Nanocarbon reinforcement of this interface is the logical solution, but conventional dispersions create more problems than they solve.
Flexiphene™ disperses nanocarbon uniformly throughout the composite matrix so that the fiber-matrix interface is reinforced at every point — not just where clusters happen to land.
Flexiphene™ liquid dispersion integrates directly into resin infusion, prepreg, and wet layup processes. Nanocarbon particles migrate to and anchor at the fiber-matrix boundary during cure.
High-aspect-ratio nanotubes spanning across emerging cracks provide bridging ligaments that must be pulled out or broken before delamination can propagate — requiring significantly more energy per crack advance.
Nanocarbon networks between composite plies reinforce the through-thickness direction — historically the weakest in laminated structures. Interlaminar shear strength and Mode I/II fracture toughness are enhanced without modifying the fiber architecture.
Under ballistic or blast loading, the nanocarbon network absorbs and redistributes energy across a larger area before local failure initiates. This delays penetration and reduces back-face deformation in panel applications.
Surfactant-free dispersion means the fiber-matrix bond itself is not degraded. In-plane tensile and compressive properties are preserved or improved — unlike surfactant-based additions that reduce modulus to gain toughness.
Works with CFRP, GFRP, aramid (Kevlar®), UHMWPE, and hybrid fiber systems. Compatible with epoxy, vinyl ester, phenolic, and polyurethane matrices used in defense and aerospace fabrication.
Hard armor plates and soft armor backing panels where improved delamination resistance translates directly to enhanced V50 performance without increased areal density.
Structural composite panels requiring improved impact damage tolerance and delamination resistance under bird strike, hail, and FOD scenarios.
Hull and bulkhead panels in naval vessels where blast overpressure loading demands enhanced energy absorption and delamination arrest in composite structures.
Composite appliqué armor for ground vehicles where weight savings over ceramic and steel alternatives require the composite matrix itself to carry more structural load under ballistic events.
CFRP primary and secondary structures requiring enhanced microcrack resistance under thermal cycling and MMOD (micro-meteoroid and orbital debris) impact scenarios.
Blast-resistant composite cladding and structural wrap systems for critical infrastructure protection where delamination under pressure wave loading must be mitigated.
