Heat-resistant sandwich structure with carbon fiber-polyimide composite faces and a carbon foam core

Mechanical properties of low‐density heat‐resistant polyimide‐based advanced composite sandwich panels

“…TriA-X is a commercial phenylethynyl-terminated imide oligomer resin, and GraFoam is commercial carbon foam. The DMA result of the aforementioned CF/TriA-X thermoset composite face was similar to the result of PAA-TS in this study, whereas the flexural force values of the HRACSs The onset temperature at DMA ( C) Density (kg/m 3 ) Sandwich Panel Ogasawara et al [7] HRACS with 5 mm core thickness…”

“…In the literature about heat-resistant advanced sandwich composites based on all this information, one may argue that heat-resistant advanced sandwich composites have not been sufficiently included in the literature, except for the study by Ogasawara et al [7] Ogasawara et al [7] prepared a heat-resistant sandwich composite consisting of a CF/TriA-X thermoset advanced PI composite face and a GraFoam carbon foam. TriA-X is a commercial phenylethynyl-terminated imide oligomer resin, and GraFoam is commercial carbon foam.…”

“…This is substantially caused by the poor availability of heat-resistant materials for face sheets, cores, and adhesives. [7] In the literature, it is possible to find separate studies focusing solely on PI foams or fiberreinforced PI-based composites.…”

“…As mentioned, there have been few studies on sandwich composite panels that have combined fiberreinforced PI-based advanced composites and PI foams in the literature. Ogasawara et al [7] presented the processing and properties of a new heat-resistant sandwich structure that consisted of CF-reinforced PI matrix composite face sheets and a carbon foam core. A novel phenyl ethynyl-terminated imide oligomer (TriA-X) was used for both the matrix resin and the film adhesive.…”
