The paper substantiates the Tsai–Melo computation method in determining the monolayer elastic constants of the layered polymer composite material (PCM). It develops an algorithm and a computation program in the MS Excel based on the Visual Basic for Applications (VBA) built-in programming language to compute main mechanical characteristics of a PCM layer based on the Tsai–Melo invariants. The paper provides an example in computing the composite monolayers selected for testing. Tables, diagrams and graphs of the obtained monolayer mechanical characteristics for different options of laying the composite package selected for testing are compiled. Computation accuracy is assessed in comparison with calculations in the ANSYS package and the results of testing the PCM samples.
