Abstract:
1. A method for manufacturing a body of revolution comprising: introducing at least one first heated composite strip formed of intimately mingled continuous strands formed of glass filaments and filaments of organic thermoplastic into at least one die, said first composite strip having a width from about 1 to about 10 cm; simultaneously feeding at least one molten material into the die to obtain at least one second composite strip, said second composite strip being formed of said molten material reinforced with said at least one first composite strip; and winding the second composite strip around a support rotating about its axis, wherein an amount of said molten material deposited on one side of said first strip is greater than an amount of said molten material deposited on a second side of said first strip, resulting in an off-centering of said glass filaments within said second composite strip.
