To achieve weight reduction at low cost, a seat frame structure in automotive vehicles made of polymer matrix composite (PMC) was developed. A sample seat frame structure was designed and analysed using finite element analysis (FEM) in order to design and manufacture. Analyses were done for several cases suggested in various safety regulations of Federal Motor Vehicle Safety Standards (FMVSS). Each result was utilized to modify the actual shape to obtain a lighter, safer and more stable design. The strategy of appropriate design was used to produce a sample bottom plate of the seat structure with reinforced by X-shape frame. It was found that the substitution of material by PMC resulted in a weight reduction effect with equivalent strength and impact characteristics. Finally, the most desirable geometry for X-shaped frame was proposed to obtain the effective performance.
