  • Compositions useful for preparing composites and composites produced therewith
    Patent number: 8445590
    Abstract: A composite prepared using a thermosettable epoxy resin composition having, as components: (1) an epoxy resin; (2) an epoxidized cycloaliphatic dicyclopentadiene phenolic resin; (3) an optional epoxidized bisphenol-A novolac resin; (4) an optional oligomeric butadiene; (5) an optional organic solvent; and (6) an alkylphenol novolac resin, the alkylphenol novolac resin serving as a curing agent. The composite so prepared may have good physical properties and superior a electrical properties as compared to conventional composites, such as laminates. The prepregs used to make the laminates may have a better surface appearance as well.
