Mechanical Properties of Processed Needlepunched Material of Complex Composition

详细

We have studied the performance of different methods for processing needlepunched material made from blends of polyester, bicomponent, and polypropylene fibers. The performance of needlepunching and various processing methods depends on the choice of parameters for evaluating the mechanical properties of the materials. A correlation has been found between different parameters used to evaluate the deformation-related and strength-related properties of the original needlepunched materials. However, there is no such correlation for the processed materials.
