Abstract Lightweight flexible polyimide foams (PIFs) with different rigid‐flexible molecular structure networks are prepared by microwave‐assisted foaming of polyester ammonium salt (PEAS) precursor powders, followed post curing process to complete final imidization. The optimum temperatures PEAS precursors range from 85 135 °C, and the melting rate is adjusted meet volatile releasing fabricate PIFs. Results show that PIFs nearly fully open cell (99.99%), micron pore sizes (400–500 µm),...
The mechanical properties of carbon fiber/epoxy (CF/EP) composites are often limited by the low performance epoxy resin, leading to damage initiation and eventual failure composites. To enhance their performance, an amino-functionalized poly(ether sulfone) (APES) was synthesized employed as a modifier for resin used fabricate CF/EP via hot-pressing. APES is capable participating in curing process dispersing uniformly matrix. results demonstrated that introduction improved resin's tensile...
In order to enhance the ablation resistance in prolonged high-temperature conditions and concurrently elevate mechanical property heat of epoxy resins, a "rigid-flexible" cocross-linked resin was synthesized through copolymerization silicone bismaleimide. With addition 20 phr bismaleimide (B7D3) 50 silicone, EP-B7D3@50P shows excellent due rigid flexible ceramizable network. The glass transition temperature increased by 16.4 °C compared resin. Most significantly, mass linear rate dropped...
The development of nano-reinforced materials to form structural composites relies on controlling interfaces between nanomaterials and the bulk material yield that can be applied in fields such as aerospace, wind power energy, transportation. This paper describes experiments design control micro–nano multi-scale interfacial reinforced carbon fiber using electrodeposition electropolymerization a one-step method. First, adhesion graphene oxide (GO) nanosheets surface was effectively enhanced...
In this work, the modulation of phase size silicones was achieved by regulating degree curing. The effect silicone on mechanical, thermal and ablative properties epoxy resins also investigated. increase in pre-curing slowed down exothermic curing process reduced number precipitated phases leading to a large-sized structure. Nevertheless, increased grafting rate induces formation homogeneous structure resin. Excessively large sizes are detrimental mechanical properties. Small-sized contribute...
The properties of fiber–matrix interfaces are one the most important factors that influence performance carbon fiber-reinforced polymer (CFRP) composites.
