Definitions
- the invention relates to an injection molded part made of plastic, in particular a fitting part for the interior of a motor vehicle, wherein the plastic is attached to a fiber. Furthermore, the invention relates to a compound for producing the injection-molded part and a method for manufacturing the injection-molded part.
- glass fibers are suitable as filler only conditionally for use in visible parts, since they are visible on the visible surface. This especially in the infusion area or at the weld lines.
- talc is often used as filler in such cases.
- talc-based plastics generally do not achieve such high strengths.
- the invention has for its object to provide an injection molded part of the type mentioned, in which the fibers are not or only marginally on the surface and still has good strength.
- an injection molded part made of plastic in particular a fitting for the interior of a motor vehicle, wherein the plastic is attached to a fiber
- the fiber attached to the plastic is a cellulose-based natural fiber.
- Such fibers are softer and more flexible than glass fibers and are therefore less noticeable on the surface.
- preferably flat surfaces are produced, which are free of fiber-caused marks.
- the reinforcing effect is better than with powdered fillers such as talc.
- wall thicknesses can be thinner and components can be made lighter.
- these fibers are made from renewable raw materials and can be easily disposed of thermally.
- the wear on the injection molds and injection molding machines is lower.
- a natural fiber is understood to mean a fiber which is produced from a natural product, here from wood.
- the fiber added to the plastic is lyocell.
- Lyocell is a cellulose-based regenerated fiber produced industrially by the direct solvent process.
- a suitable fiber is, for example, the Lenzing "TENCEL®" fiber, the fibers preferably having a thickness of from 1 to 7 dtex (grams per liter)
- Fibers with a thickness of 1.3 dtex preferably have an elongation at break of about 13% and a strength of about 37 cN / tex. With such fibers, the desired properties, namely a sufficient
- the fibers preferably have a diameter of 10 to 30 microns and are in turn made up of a bundle of macrofibrils with diameters of 0.5 to 1 pm.
- the macrofibrils are composed of microfibrils with diameters of 0.1 to 0.2 pm and the microfibrils are preferably made of nanofibrils with Diameters of 10 to 100 nanometers built.
- a fiber is preferably used, which has a total of four nested structure levels. These are on the one hand the actual fibers, the macrofibrils arranged therein, the microfibrils contained therein and the nanofibrils contained therein again. These are in each case aligned in fiber extension structures.
- plastics a variety of different compositions come into consideration. Particularly preferred is polypropylene.
- Another aspect of the invention is the provision of a compound for making injection molded parts comprising a plastic and a cellulose-based natural fiber, especially lyocell.
- a further aspect of the invention is to provide a method for producing an injection-molded part according to any one of the preceding claims, which is characterized in that the fibers are fed to an injection molding machine in the form of granules with a high fiber content.
- the fibers are cellulose based fibers, especially lyocell.
- the fibers are fed into the injection molding machine in the form of a masterbatch.
