The Study of Different Type of Fibers for Using as the Ablative Materials

Abstract

Ablative composite materials are required for using in solid motor rocket nozzles and follow on long range ballistic rockets which are multi-component mixture of resins, fibers and fillers. To increase the ablation resistance efficiency, the ratio of percent of materials were studied by using Oxyacetylene ablation testing which shown the result in burning time of the flame passing through the sample. The radiographic images were also captured to study the void of the laminate samples from compression molding process. The lowest ablation rate of this study shown that the 60 percent fiber glass which adhered with the 40 percent resin gave the best results.
