Abstract:

Three-dimensional automobile cushion were designed and prepared to study compression fatigre resistance. Spun polysulfonamide yarn was chosen to wave surface layers and polyvinylidene fluoride filament to wave spacer structure. Four kinds of weave structures were designed based on different combinations of plain, hexagonal and diamond weave. And the thickness was adjusted on the basis of one structure. Six kinds of samples with different layers and thickness were designed and the compressive properties of the samples were tested. Then, compression fatigue resistance curve and damage pattern were analyzed and compared, and the relevant parameters influencing the compression properties were studied. The result shows that the denser the surface structure is, the better the fixation of spacing filaments, and the heavier load the fabric will support, and the better the compressive properties and in a certain range, the greater the thickness is, the better compressive properties.
