Abstract

Carbon/Phenolic Composites (CPCs) are essential to manufacture many portions of the nozzle assembly of Solid Rocket Motors (SRMs) which are essential both to preserve the independent access to space as well as for the homeland security. In our research, a feasible approach aimed at preliminary retrieving the in-plane and out-plane thermal diffusivity of CPCs through the Oxy-Acetylene Torch (OAT) tests was validated. The proposed approach showed to be effective and able to bypass some limitations of common protocols, especially in terms of capability to determine the thermal diffusivity of CPCs at high heating rates. A comprehensive work of comparison of the obtained data with state-of-the-art CPCs such as MX-4926 and FM-5014 has also been carried out, evidencing the effectiveness of the proposed method.

摘要

碳/酚醛复合材料（CPCs）对于制造固体火箭发动机（SRMs）的喷管组件的许多部分至关重要，这对于保持独立进入太空以及国土安全都至关重要。在我们的研究中，一种旨在通过氧乙炔炬（OAT）测试初步获取CPCs面内和面外热扩散率的可行方法得到了验证。所提出的方法被证明是有效的，并且能够绕过常见协议的一些限制，特别是在高加热速率下确定CPCs热扩散率的能力方面。还对获得的数据与诸如MX - 4926和FM - 5014等先进CPCs进行了全面的比较工作，证明了所提出方法的有效性。
