摘要 |
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. |
