Greetings to all! I am interested in carbon fiber but I am very new in it. Is there any way to calculate the maximum load on the manufactured product depending on the number of layers and their density ( or something else)? Thanks to all in advance.

Yes you can calculate maximum loads. But everything but the easiest case (a unidirectional c.f. rod rod under straight tension) quickly becomes mathematically challenging, including tensor multiplication etc.. and to set up the equation you will need some skills in static/dynamic mechanics. Additionally some of the mechanical propertys you need are very hard to get/ have to be determined by experiments.
