To determine experimentally the thermophysical properties (\u03bb, \u03c1, Cp,) and the kinetic triplet (Ea, A, n) from ambient temperature to 1000\u00b0C, dedicated experimental apparatus are used. An experimental procedure has been carried out on a generic silicone-based composite, it consists of a silicone matrix with short carbon fibres and silicon carbide powder. First, thermogravimetric analysis has been conducted on the material at different heating rate and confirming the complex thermal degradation, thus under inert atmosphere, the weight of the material decreases up to 28.8%. From these results, a kinetic mechanism degradation and a methodology for a correct estimation of the triplet kinetic parameters are proposed. Several apparatuses have been used to determine the thermophysical properties such as Calvet calorimeter, Differential Scanning Calorimetry, dilatometer and laser flash analysis, from this result the thermal conductivity is estimated. Once the properties are determined, the measured data has been implemented in a finite element 1D approach, showing the efficiency of the generic silicone-based composite as a thermal barrier.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_990964.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_990964.pdf\">Download the Full Paper &gt; <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>G.
