摘要：

The mechanical performance of fiber-reinforced phenolic foam is characterized and compared with unreinforced foam in terms of friability, compression and shear properties, and flexural behavior of simple sandwich beams. Compared with conventional phenolic foam, foam reinforced with aramid fibers exhibits significantly lower friability, higher resistance to cracking, and more isotropic behavior, while glass fiber-reinforced foam is significantly stiffer and stronger. Sandwich structures with reinforced phenolic foam cores show unique failure behavior, in which catastrophic collapse of the structure is not only delayed, but avoided altogether. The findings in this paper, coupled with earlier results, demonstrate the potential of reinforced phenolic foam as a fire-resistant, tough and low-cost engineering material.
