Polymer Matrix
Polymer matrix is a composite material consisting of a polymer resin as the matrix (continuous phase) and reinforcing agents such as fibers, particles, or other small components dispersed throughout the matrix (discontinuous phase). In the context of space and astronautical engineering, polymer matrix composites are widely used due to their high strength-to-weight ratio, excellent fatigue resistance, and good thermal stability. They are used in various applications such as spacecraft structures, rocket motor cases, and satellite components. The selection of the polymer matrix and reinforcing agents depends on the specific requirements of the application, such as the desired mechanical properties, environmental conditions, and cost.
