摘要：

Novel fiber-reinforced dicyanate of bisphenol A (BADCy)/poly (urea-formaldehyde) microcapsules filled with epoxy resins (MCEs) composites were prepared. The effects of MCEs with different content and diameter on the mechanical properties and the hot-wet resistance of the composites were discussed. The morphologies of composites were characterized using a scanning electron microscopy and optical microscopy. The dynamic mechanical property (DMA) of the composites was also evaluated. The results indicate that the appropriate addition of MCEs with various diameters can significantly improve the mechanical properties and the hot-wet resistance of fiber-reinforced BADCy composites. The fiber-reinforced BADCy/MCEs composites have lower glass transition temperature (T(g)), compared with the fiber-reinforced BADCy composites without MCEs.
