  • Publication number: 20030086995
    Abstract: Continuous strand pellets made of particles, in which reinforcing staple fibers are arranged in a thermoplastic matrix in a helical manner, are provided. The reinforcing staple fibers and the molten matrix material are situated in a peripheral area of the particles and, together with unmolten thermoplastic staple fibers, are present in a core area of the particles. A method for producing the continuous strand pellets from a staple fiber mixture of thermoplastic fibers and reinforcing fibers includes feeding the staple fiber mixture through a preheating zone and then drawing the staple fiber mixture through a heating nozzle to form a strand, which after rotating and consolidation by cooling, is cut into continuous strand pellets.

  • Patent number: 6548167
    Abstract: A continuous fiber granulate material includes granulate particles having reinforcing staple fibers helically arranged in a thermoplastic matrix. The reinforcing staple fibers are located in a sheathed zone of the granulate particles along with a melted matrix material, with the granulate further including a core zone having unmelted thermoplastic staple fibers. The continuous fiber granulates have good free-flowing properties and a uniform distribution of reinforcing fibers.
