として注目されている。2. Description of the Related Art Glass fibers are fiber reinforced plastics containing a thermosetting resin or a plastic resin as a matrix.
(FRP), fiber reinforced metal (FRM), etc. are used as reinforcing fibers for various composite materials. By compounding fibers in a matrix, such a composite material realizes excellent physical properties such as high tensile strength, high rigidity, and low coefficient of thermal expansion that cannot be achieved by the matrix material alone. In recent years, glass fibers, especially oxynitride glass fibers, have attracted attention as reinforcing fibers for composite materials due to their high heat resistance.

る。In such a composite material using glass fibers, the dispersion state of the fibers in the matrix material has a great influence on the properties of the composite material, and the fibers are well dispersed in order to obtain excellent mechanical properties. There is a need. In order to obtain a homogeneous composite material in which such fibers are well dispersed, a reinforcing fiber roving composed of a large number of fibers is sufficiently opened,
There must be a gap between the fibers to impregnate the matrix material. For example, in the case of continuously producing a unidirectional reinforcing material, a prepreg (precursor) is generally produced. Need to be impregnated. Such fiber opening is necessary not only when manufacturing FRP but also when compounding with a metal material such as aluminum.

ＦＲＭの断面を図２に示す。In order to produce FRM using the apparatus of the present invention, the reinforcing fiber bundle 6 is passed through the sizing agent washing tank 1 as in the conventional production method, and the sizing agent (polyethylene glycol, etc.) applied during spinning is sufficient. Wash out. The reinforcing fiber bundle 6 is preferably an oxynitride glass fiber having an appropriate number of filaments coated with a binder to form roving. Then, the washed fiber bundle is brought into contact with the fiber-spreading section 5 including the fiber-spreading rollers 3 and 4 equipped with Teflon. The glass fiber bundle 6 is sufficiently opened before it reaches the rear roller 4 from the front roller 3.
Then, this fiber bundle was introduced into the molten aluminum 6 melted at 850 ° C. and then pulled up (fiber volume content V
f = 30%). When the obtained FRM was cut and the inside was examined, the reinforcing fiber was sufficiently opened. When this strength was measured, it was 75 kg / mm 2 . The cross section of the obtained FRM is shown in FIG.
