Based on the PVK FDEANST system, the PR performance as a function of the photosensitizer has been studied [54], It is apparent that varying the sensitizer changes the photogeneration rate and greatly influences both optical gain and diffraction efficiency. By replacing TNF with TNFDM, the spectral sensitivity of composites can be extended to the near infrared (IR) region. 

The sensitivity of composite propellant is lower than predicted from the mixture of NH4ClO4-.Al.That may be because the composite propellant is a solid rather than a powder. 

Theoretical investigations into phenomenon of the notch sensitivity of composites have tended to rely on classical fracture concepts. ITiese efforts have taken two forms micro-and macro-mechanical representations. In die micro-mechanics format, local... 

Binding agents include resins, waxes, plastics, and oils. These materials make the finely divided particles adhere to each other when compressed Into pyrotechnic items. They also prevent segregation and ensure a more uniformly blended composition. Binders also help to obtain maximum density and increased burning efficiency. In addition, they serve, in some cases, to reduce the sensitivity of compositions that otherwise would be unduly sensitive to shock and friction.
