- Abstract
- Knowledge of high temperature reactions of organic vapors is important in establishing the performance characteristics of ablative heat shields employing organic polymers, especially when a char layer is formed during the ablative process. To complement their own study of the performance characteristics of polymeric ablative heat shields, Lockheed Missiles and Spce Company requested that Stanford Research Institute undertake a study to establish quantitatively the chemical behavior of pyrolysis products as they pass through simulated char layers. This study commenced on December 1, 1961 under Purchase Order 18-10399 under Prime Contract NOrd 17017. It was conducted in two parts: (1) Part A, an evaluation of the behavior of synthetic pyrolysis products when passed through synthetic chars (porous carbons); (2) Part B, an evaluation of the products of initial pyrolysis of char-forming polymers. Part B consisted essentially of an evaluation of the literature and the results were summarized in a separate report.
