3M™ Matrix Resin 8831 is a two‑part, ultra‑low viscosity, Bis‑A epoxy that is curable at low temperatures. This resin offers balanced compressive and toughness enhancements with processability optimized for room temperature filament winding, pultrusion, vacuum infusion and RTM processes.

3M™ Matrix Resin 8831, a two part, ultra-low viscosity, Bis A epoxy matrix resin, was developed using our advanced, proprietary nanoparticle technology that enables significantly higher loadings of uniformly dispersed nanoparticles. The resulting high performance formula yields tougher composites with higher shear elasticity to meet specifications in the aviation industry.

This matrix has enhanced wear characteristics for industrial rollers that eliminate the need for hybrid metal/composite designs, while low cure temperatures enable designs with thermoplastic components. 8831 provides improved resistance to bursts, fatigue and impact in pressure vessels which can lead to longer part life. Lower coefficients of thermal expansion (CTE) help improve dimensional stability in thick wound parts, resulting in lower residual stresses. With its increased compressive strength and stiffness that enable longer and lighter wind blades, turbine efficiency can be enhanced.

3M™ Matrix Resin 8831 offers lighter weight and faster manufacturing. It also decreases pull force required in the pultrusion process, enabling higher fiber volume or faster processing. This product has a 2 year shelf life at room temperature.

Suggested Applications

  • Filament wound pressure vessels including CNG, Hydrogen or SCBA
  • Pultruded or wound tubes or shafts (typical temperature industrial rollers)
  • Pultruded wind blade spars

Start with Nanoparticles
Carbon fiber composite products are limited by their compression strength. Under compressive loading, carbon fibers can micro-buckle (like a small wrinkle) resulting in breakage or failure of the composite product.

We successfully created a resin with a high concentration of uniformly dispersed nanoparticles that makes a stronger composite. These nanoparticles are so tiny, they can uniformly surround and support the carbon fibers, significantly increasing the shear modulus of the resin and effectively delaying the micro-buckling of the carbon fibers. The greater the nanoparticle loading, the stiffer the support of the carbon fiber. Where other nanotechnologies (like carbon nano tubes) deliver <3% nanoparticles loading, our proprietary technology uniquely enables loadings of >40% of uniformly dispersed nanoparticles. Conventional-sized fillers are simply too large to completely surround the fibers and difficult to disperse uniformly in the resin. With 3M™ Matrix Resin 8831, the exceptional bond between the particle and the resin hinders crack proliferation by creating a complex path that effectively dissipates energy. The result: tougher composites.

Strength Two Ways
3M significantly increases resin shear modulus while simultaneously adding fracture toughness. In the past, attempts to increase resin stiffness resulted in a significant decrease in fracture toughness, producing very brittle materials. 3M's proprietary nanoparticles technology creates such a strong bond between the particle and the resin that energy is dissipated when the composite is stressed, preventing crack propagation.
