Resin-based composites used in spacecraft face risks from space debris and high-energy charged particles during their long-term service in the space environment. This work proposes a novel microcapsule (MC) and its cyanate ester (CE) resin-based composites (CE/MCs) with self-healing ability and gamma radiation shielding ability. The multifunctional epoxy/lead tungstate (EP@PWO) microcapsules are developed through self-assembly method and in-situ precipitation method. These microcapsules and curing agent 4,4′-diaminodiphenylsulfone (DDS) are incorporated into the CE resin to form resin-based composites with low curing temperature, self-healing ability, and gamma radiation shielding ability. Various approaches including chemical characterizations (X-ray diffractometer, fourier-transform infrared, energy dispersive spectrometer), microscopy (optical microscope, scanning electronic microscope), and thermal analysis (differential scanning calorimeter, thermogravimetric analysis) are utilized to demonstrate the successful encapsulation of the EP resin by PWO shell and good thermal stability of this material. The mechanical property, self-healing ability, and gamma radiation shielding property are investigated via fracture toughness test and using a NaI (Tl) spectrometer. In comparison with pure CE resin, the fracture toughness of the CE/MCs composites can increase by 66.5%, and the self-healing efficiency can reach up to 56%, indicating that the microcapsules have good toughening and self-healing abilities. The microcapsules and their composites also exhibit good gamma radiation shielding properties. 相似文献

As part of the National Center for Manufacturing Sciences contract on adhesive bonding of dissimilar materials, UTRC, as a sub-contractor, is evaluating environmentally acceptable surface preparation techniques for selected metals and composites. The selected processes are automatable and capable of being transferred into the manufacturing arena. One aspect of the programme is the evaluation of plasma-sprayed, microporous, thin coatings as surface pretreatments for both resin-based composites and metals. Mechanical test results are presented which demonstrate the viability of this approach to achieve acceptable joint strengths with steel, titanium and aluminium bonded to several types of resin-matrix composite. The environmental impact, by elimination of organic primer systems and strong acid etching and anodizing solutions, will be discussed. 相似文献
