A composite material is composed of two or more materials that when combined, provide superior properties to those of the individual constituents.
In this case we are referring to fibre reinforced polymer (FRP) composites, which typically use glass, carbon, aramid or natural fibres in combination with polymer resins. PureGRAPH® graphene is generally mixed with the resin prior to combination with the textile reinforcement.
FRP Composites are typically used in place of metal structures and components where reduced weight is required, however, PureGRAPH® graphene has been shown to provide a significant step-up in performance of composite materials compared with many other graphene products.
Features and benefits of using PureGRAPH® additives in composites as follows:
Disperses well in resins
Easy to use and good dispersion leads to high performance
Increased mechanical strength
Increased composite performance or potential for light-weighting with unchanged performance. Light-weighting of composites could lead to reduced fuel consumption, increased vehicle performance, reduced emissions and potential cost savings
Increased flexural strength of laminates
Potential for thinner and lighter weight composite panels and vandal-proof composite materials
Improved water resistance
Enhanced barrier properties for aquatic applications or where water penetration is an issue
Increased electrical and thermal conductivity
Improved static removal properties and enhanced thermal management characteristics
Potential for improved safety in critical applications
• Efficient barrier to oxygen
• Suppression of toxic and flammable volatiles
• Alternative to harmful chemicals
• May be used as an additive in an existing FR formulation
Simplified manufacture of composite components
Reduction in localised curing issues
