Design And Analysis Of Discontinuous LongFiber Reinforced Thermoplastic Structures ForCar Seat Applications

Discontinuous long fiber reinforced polymers (DLFRP) with a remaining fiber length of 6 to 8 mm after processing reach up to 10 % higher mechanical properties compared to classical short fiber reinforced plastics. Fracture toughness was observed to be even three times higher, DLFRP is processed by injection or compression molding, applicable in mass production and so can lead to a reduction of the component number by a highly integrated design. The strongly computer aided investigations and the following component tests with prototypes for car seat structures showed that DLFRP can advantageously replace structural metal components. In appropriate applications they are capable to save weight and manufacturing costs.
