| titleOfInvention | Bundle of chopped fibers, molding material and fiber-reinforced plastic, and process to produce them |
| abstract | A bundle of chopped fibers CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g comprising: (a) a large number of reinforcing fibers arranged unidirectionally (11) and a grouping agent that groups said large number of reinforcing fibers (11) , where (b) the fiber length of said reinforcing fiber (11) is from 5 to 100 mm, (c) said bundle of chopped fibers (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g) has a first section of transition (13a) in which the number of said reinforcing fibers (11) in a cross section of the fiber bundle (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g) perpendicular to the direction of arrangement of said reinforcing fibers ( 11) increases from a first point (12a) which is a point in a direction of arrangement of said reinforcing fibers (11) towards a second point (12b) which is another point and also has a second transition section (13b) in where said number of reinforcing fibers (11) in the cross section of the fiber bundle (CFB, CFB1, CFB2, CFB3, CFB5a -CFB5g) increases from said second point (12b) towards said first point (12a), and (d) having said bundle of chopped fibers (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g) a constant section (14) located between said first transition section (13a) and said second transition section (13b) in the direction of arrangement of said reinforcing fibers (11) in which said number of reinforcing fibers (11) in the cross section of the fiber bundle (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g) is constant, where an end face of said constant section (14Ea) coincides with a first terminal end face (13Ea) of said first transition section (13a) which is at an opposite end of said first tip (12a) while another end face of said constant section (14Ea) coincides with a second terminal end face (13Eb) of said second transition section (13b) that is opposite said second tip (12b), or where said first terminal end face (13Ea) coincides directly with said second terminal end face (13Eb), and where (e) between said first point (12a) and said second point (12b), the change in the total cross-sectional area of the reinforcing fibers (11) in said fiber bundle cross section (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g), measured along the direction of arrangement of said reinforcing fiber (11), is 0.05 mm2 or less per 1 mm , and characterized in that the maximum value of a total cross-sectional area of said reinforcing fibers (11) is less than 0.1 mm2 and, between said first point (12a) and said second point (12b), a change in the number of said reinforcing fibers (11) in the cross section of the fiber bundle (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g), measured along the direction of arrangement of said reinforcing fibers (11), is of 30% or less of said maximum number of reinforcing fibers (11) per 1 mm and / or where said reinforcing fibers (11) are carbon fibers, the number of said carbon fibers (11) is from 1,000 to 700,000, and between said first tip (12a) and said second tip (12b), a change in the number of said reinforcing fibers (11) in the cross-section of the fiber bundle ( CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g), measured along the direction of arrangement of said reinforcing fibers (11), is 1,400 or less per 1 mm and / or where a value of the Wb / Tb is from 20 to 400, where Wb represents the width of said fiber bundle (11) measured perpendicular to the direction of arrangement of said reinforcing fibers (11) in a plan view having a state in which said width is larger, while Tb represents the maximum thickness of said chopped fiber bundle (CFB, CFB1, CFB2, CFB3, CFB5a-CFB5g) measured perpendicular to the plan view. |
