The invention, within the field of research of composite materials for automobiles, relates to a long fiber composite passenger car rear seat frame initial material design method. The method comprisesthe following steps: 1. determine the crashworthiness requirements of the rear seats of passenger cars; 2. derivating the minimum penetration energy function of the LFT plate; 3. studying the designmethod of LFT flat material based on impact energy requirements; 4. Designing the initial material of the seat backboard skeleton; 5. verifying the initial design results finite element and test; themethod establishes a bridge connecting the energy absorption capacity with the material parameters and the test constraint parameters by using the minimum penetration energy of the LFT plate. On the one hand, the ultimate impact energy of the LFT plate is estimated, and on the other hand, the initial design and selection of the LFT material is guided; the practical application of the engineering of the present invention ass
