Description
Technical field
The present invention relates to performance resins based composites field, thermosetting epoxy resin material relating to a kind of toughening modifying specifically and preparation method thereof.
Background technology
Because current epoxy-resin systems material is more crisp, upper limit use temperature is lower, and process limitation is comparatively large, and the most frequently used resin of polymer matrix composites has thermosetting resin and thermoplastic resin, and the matrix of carbon-fibre composite is based on thermosetting resin.Thermosetting epoxy resin system itself has certain defective, according to Griffich fracture theory, the subsurface defect such as failure crack, crazing is there is in pure thermosetting epoxy resin after solidifying completely, when being subject to external impacts, these defects can expand development rapidly, external enwergy is converted into the surface energy producing new crackle, after exceeding some strength, can expand rapidly until broken.If add a certain amount of toughner in its system, and be uniformly distributed, can part energy be absorbed when external enwergy is impacted, thus avoid material fragmentation.
Thermosetting epoxy resin toughness reinforcing method has rubber elastomer toughening modifying, Toughened With High Performance Thermoplastics modification, block copolymer-modified, oligomeric silsesquioxanes is structurally-modified.Toughened With High Performance Thermoplastics is the spheroidal particle network-spherulitic texture forming epoxy resin parcel thermoplastic resin, this structure can dispersive stress, absorb energy, produce viscous deformation, suppress the expansion of crackle, realize the toughness reinforcing of epoxy resin.Cardo polyetherketone (PEK-C) is a class semicrystalline thermoplastic resin, and second-order transition temperature, far above polysulfones (226 DEG C), has good toughness, good mechanical property, creep-resistant property excellence, and has fire-retardant, anticorrosive, resistance to elevated temperatures.
