3M™ Matrix Resin 8832 is a two-part, low viscosity, nanoparticle modified Bis-A epoxy curable at low temperatures. 8832 can be used in filament winding, pultrusion and with typical heated bath processes. Our proprietary matrix technology allows nanoparticles in between each carbon fiber, significantly increasing both shear modulus and fracture toughness.

3M™ Matrix Resin 8832, a two part, low viscosity, nanoparticle modified 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 provides improved performance after impact for exposed tubes or shafts, as well as lower residual stresses in manufactured parts, which can lead to longer part life. The higher torque carrying capacity for rotating tubes and shafts allows for longer, stronger or lighter weight designs, along with new RTM part designs with improved performance and/or lighter weight. 8832 features enhanced fracture toughness that results in reduced microcracking, and lower coefficient of thermal expansion (CTE) and shrinkage during cure enable single piece flywheel designs.

Suggested Applications

  • Pultruded or wound tubes and shafts exposed to normal environmental impacts
  • High energy flywheels
  • RTM structural parts requiring high toughness and compressive strength

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 8832, 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.
