A process is provided for thermal molding an article with at least one layer of thermoplastic fibers that are non-woven and uni-directionally oriented in combination with at least one layer of reinforcing fibers. The reinforcing fibers including glass, carbon, nature based, and combinations thereof; alone or mixed with chopped thermoplastic fibers. Upon subjecting the layers to sufficient heat to thermally bond in the presence of non-oriented filler fibers, thermoplastic fiber fusion encapsulates the filler fibers. The filler fibers impart physical properties to the resulting article and the residual unidirectional orientation of the thermoplastic melt imparts physical properties in the fiber direction to the article. By combining layers with varying orientations of uni-directional fibers relative to one another, the physical properties of the resulting article may be controlled and extended relative to conventional thermoplastic moldings. The uni-directional fibers may have discontinuities along the length of individual fibers.

A composite material includes a thermoplastic matrix resin and carbon fibers A including carbon fiber bundles A1 in which Li/(Ni×Di.sup.2) is 6.7×10.sup.1 to 3.3×10.sup.3, and a thermoplastic matrix resin. The carbon fibers A have a fiber length of 5-100 mm and the carbon fiber bundles A1 are contained in an amount of 80 vol % or larger but less than 100 vol % with respect to the carbon fibers A and wherein removal of the matrix resin from the composite material gives a carbon fiber mass which, when compressed to a thickness of Tf, has a repulsive force P of 0.05-1.00 MPa A method for producing the composite material including subjecting a composite composition to an impregnation treatment with a compression/impregnation device.

A method of separating carbon fiber tows. The method includes separating two or more first carbon fiber tows from a first tow band onto a second elevation to form two or more second carbon fiber tows from a second tow band. The two or more second carbon fiber tows from the second tow band leave gaps next to first adjacent tows of the two or more first carbon fiber tows remaining from the first tow band after the separating step. The first adjacent tows from the first tow band leave gaps next to second adjacent tows of the two or more second carbon fiber tows from the second tow band.

A tow prepreg manufacturing apparatus applies resin to an original tow of reinforcing fibers. The tow prepreg manufacturing apparatus includes an oiling roller, a scraper, a resin reservoir, a tube pump, and a controller. The oiling roller is supplied with resin while rotating at a predetermined rotation speed. The scraper adjusts the shape of the resin supplied onto the oiling roller. The resin reservoir supplies resin to the oiling roller. The tube pump discharges resin to the resin reservoir. The controller controls the tube pump so that the amount of resin held in the resin reservoir remains constant and controls the rotation speed of the oiling roller so that a resin content of a wound tow prepreg becomes equal to a target resin content.
