In a sheetlike composite comprising a polyolefin matrix and natural fiber mats as reinforcement the natural fibers have a basis weight of more than 10 dtex. Sisal fibers are preferred. The composites are used in particular in automotive construction.

Sheetlike composite

The invention relates to semifinished material consisting of a thermoplastic polymer and a needled textile fabric made up of at least two layers of oriented continuous filament yarn, each having an areal mass of not more than 300 g/m.sup.2, and at least one layer of unoriented fibers.

Fiber-reinforced thermoplastic panels

Semifinished material consisting of symmetrically-needled glass-fiber mat impregnated with a thermoplastic polymer. The glass mat can be made by, for instance, needling continuous filament web from above and below at the same time with a double needling machine.
