摘要: Phenolic impregnated carbon ablator (PICA), which is composed of the phenolic resin (PR) and fiber, particular interest to researchers in aerospace field. In this work, PICA was prepared by double-stage isothermal heating curing. Then, curing kinetics boron-modified (BPR) investigated non-isothermal differential scanning calorimetry method order optimize temperature BPR. Further, effect rate during process on compressive strength discussed detail. The experimental data show that BPR needs more energy so under different condition higher than virgin PR. Notably, with increasing process, micro-cracks increase decreases. Once exceeds a critical value, no longer has insignificant strength. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
