A structure for use in a compressible resilient pad. The structure contains both axially elastomeric strands and relatively inelastic strands co-extruded in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.

The present invention relates to a method for the production of injection-moulded, reinforced moulded parts, the fibre orientation of which is specifically adjusted on a local basis. Via suitable, dynamically controlled supplementary heating in the wall of the injection mould which is used (variotherm heatable channel), a local cavity region is hereby heated at the time of injection to a temperature in the region of or above the solidification temperature (in any case above the crystallisation temperature in the case of partially crystalline plastic materials or above the glass transition temperature in the case of amorphous plastic materials) of the polymer (plastic material moulding compound).

A three-dimensional structure manufacturing method capable of freely controlling physical properties of a three-dimensional structure is provided.

There is provided the three-dimensional structure manufacturing method including: forming a layer containing at least one type of chemical substance; and orienting molecules of the at least one type of chemical substance, the forming the layer and the orienting the molecules being repeated a plurality of times.

A composite material includes a thermoplastic polymer matrix throughout which cellulose pulp fibers and filler material are dispersed. The composite may be in solid (e.g. pellet) form, or molten form. The presence of cellulose pulp fibers unexpectedly reduces cycle time, and/or unexpectedly improves certain properties, when the composite is used in injection molding. A method for molding a part includes providing a solid composite that includes thermoplastic polymer, filler material, and cellulose pulp fibers to an injection molding system; melting the polymer to produce a molten mixture; and injecting the molten mixture into a mold. Another method for molding a part includes injecting a molten mixture of thermoplastic polymer, filler material, and cellulose pulp fibers into a mold; and removing the formed part from the mold after a cycle time at least 10% less than that required when using a comparable molten mixture that excludes the pulp fibers.
