Abstract
A thermoplastic prepreg is disclosed having fully impregnated filaments. The prepreg is formed by having a plurality of continuous fibers that are substantially oriented in a longitudinal direction, the continuous fibers constituting from about 30 wt. % to about 40 wt. % of the prepreg, a first resinous matrix that contains a first set of one or more thermoplastic polymers and within which the continuous fibers are embedded, wherein the thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg, and a second resinous matrix that contains a second set of one or more thermoplastic polymers, wherein the second set of thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg.
Claims18
A thermoplastic prepreg comprising:
- a plurality of continuous fibers that are substantially oriented in a longitudinal direction, the continuous fibers constituting from about 30 wt. % to about 40 wt. % of the prepreg;
- a first resinous matrix that contains a first set of one or more thermoplastic polymers and within which the continuous fibers are embedded, wherein the thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg;
- and
- a second resinous matrix that contains a second set of one or more thermoplastic polymers, wherein the second set of thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg;
- and
- wherein the second resinous matrix forms a layer around the first resinous matrix and the continuous fibers, wherein the layer is formed by extruding the first resinous matrix and the continuous fibers with the second resinous matrix within an impregnation die, while the first resinous matrix and the continuous fibers is twisted and under tension.
A thermoplastic prepreg comprising:
- a plurality of continuous fibers that are substantially oriented in a longitudinal direction, the continuous fibers constituting from about 30 wt. % to about 40 wt. % of the prepreg;
- a first resinous matrix that contains a first set of one or more thermoplastic polymers having fiber stabilizing characteristics and within which the continuous fibers are embedded, wherein the thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg;
- and
- a second resinous matrix that contains a second set of one or more thermoplastic polymers, wherein the second set of thermoplastic polymers constitute an additional 30 wt. % to about 40 wt. % of the prepreg, wherein the second resinous matrix coats the first resinous matrix;
- and
- wherein the second resinous matrix forms a layer around the first resinous matrix and the continuous fibers, wherein the layer is formed by extruding the first resinous matrix and the continuous fibers with the second resinous matrix within an impregnation die, while the first resinous matrix and the continuous fibers is twisted and under tension.
