| 20100297414 | COMPOSITE SHEET BASED ON HIGH PRESSURE LAMINATE SHEETS (HPL SHEETS) - A composite sheet has cover layers of high pressure laminate sheets A and a core layer B arranged therebetween. The core layer is formed for an air pore-containing, fiber reinforced thermoplastic and is adhesively bonded to the cover layers by an anhydrous adhesive which is mechanically anchored in surface pores of the core layer B. | 11-25-2010 |
| 20100116407 | Method Of Producing A Thermoplastically Moldable Fiber-Reinforced Semifinished Product - A continuous method for producing a thermoplastically moldable semifinished product of a thermoplastic material and reinforcing fibers, comprises blending thermoplastic fibers and reinforcing fibers together to form a nonwoven blend, consolidating the nonwoven blend by needling or by a thermal treatment, heating the consolidated nonwoven blend to a temperature above the softening temperature of the thermoplastic, compressing the consolidated nonwoven blend successively in a heated compression mold and in a cooled compression mold at a pressure of less than 0.8 bar for at least 3 seconds, and optionally applying functional layers to the semifinished product. The preferred product is a thermoplastically moldable semifinished product of a thermoplastic material and reinforcing fibers with an average length of 20 to 60 mm and an air pore content of 35 to 65 vol %. | 05-13-2010 |
| 20100032870 | METHOD FOR THE PRODUCTION OF FIBER-REINFORCED POLYPROPYLENE MOLDED PARTS CONTAINING PORES - Low density and acoustically absorbing panels are produced by consolidation in a mold of a heated part of a pre-cut, lofty, semi-finished product containing polypropylene fibers and reinforcing fibers and having an air pore content of 20 to 80 vol.-% wherein overlapping with the periphery of the pre-cut part are heated strips of polypropylene optionally containing up to 60 wt.-% reinforcing fibers, but containing 5 vol.-% or less of air pores. | 02-11-2010 |
