Structurally, carbon fibre reinforced composites are one of the strongest and lightest materials available for use on automotive applications. However, the polymer chemistry commonly used with reinforced composites does not provide the requirements needed to simulate that of a painted metallic component.
Significant mismatch between fibre and matrix properties results in other surface finish complications, both during curing and environmental exposure. As the matrix cures, shrinkage occurs at the resin rich regions between the carbon fibre bundles, resulting in an uneven surface profile. Also, exposure of the cured composite to high temperature and humidity causes the resin rich regions at the surface to expand and contract due to the high coefficient of thermal expansion (CTE) and moisture absorption.
In addition, these resins must be cured in a matter of minutes in order to meet the strict cycle times of the automotive industry.
Although there are some commercial resins marketed as providing a surface finish solution, these resins generally provide a void free composite surface that can be easily sanded and painted, with reduced shrinkage. It has recently come to light that the chemistry of these commercial surface finish resins still have high CTE and moisture absorption, thus not providing a complete surface finish solution and also take in excess of 15 minutes to cure.
This work will investigate the development of a low shrinkage resin system that mimics the properties of carbon fibre as close as possible to produce a rapid curing carbon fibre automotive composite.
