Abstract:
Applications of the developed procedure based on pyrolysis-gas chromatography Py-GC and principal component analysis PCA for the characterization of plastic bonded explosives PBXs are described. Due to difficulties with the commonly used normalization method a new normalization method was developed and applied in this investigation. The patterns in the score plots obtained after PCA of the Py-GC results appeared much clearer using this new method. PBX samples were examined on homogeneity, influence of the amount of antioxidant Flexzone and the crosslink density. It appears that PBXs were inhomogeneous despite a thorough mixing of the constituents during the preparation. Aging experiments were performed on samples which differed in the amount of Flexzone and in the crosslink density. As more Flexzone was added the change in the pattern of the GC-peaks became less. No relation could be found between the stability of PBXs and the crosslink density. Finally, a comparison was made between Dutch samples and samples from the UK and Norway. Small differences were observed between the samples from the three nations.
