Processing method of knitting fiber bundle to ultrathin braided fabric

Abstract

The invention discloses a processing method of knitting a fiber bundle to an ultrathin braided fabric. The processing method comprises the following steps of first, confirming whether a resin basis ofthe fiber bundle is thermosetting or thermoplastic or not; selecting a corresponding fiber bundle coated with a sizing agent; teasing and arranging cellosilk in the fiber bundle according to thickness of the braided fabric to be expanded and rolled toward two outer sides; mounting a rolling plate rolled to an ultrathin continuous fiber bundle strap on a plurality of unreeling mechanisms on fiberbundle preimpregnation equipment, and penetrating the rolling plate through a fiber preposed heating box, a double-sized resin coating device, a heating, rolling and forming combination machine, a cooling plate, a hub slitting unit and a traction machine successively; and knitting an obtained ultrathin fiber bundle preimpregnated strap to a corresponding product by a knitting machine according toa shape demand of the braided fabric. The material costs of the braided fabric and a composite material product can be controlled. The thickness of the bundle of the fiber braided fabric can be changed timely according to the mechanical demand of the product on cellosilk.

Description

Technical field: [0001] The invention relates to the production and processing field of weaving fiber tows into ultra-thin braids, in particular to a processing method for weaving fiber tows into ultra-thin braids. Background technique: [0002] With the application of new materials in industrial development, fiber materials play an important role in composite materials. They are used more and more in the fields of energy saving, weight reduction and reinforcement. The composite of single-layer or multi-layer and ultra-thin fibers of different shapes The method is currently the structural material that can best meet the above fields, and reasonably distributes the combination of different shapes of fiber layers and resins, which can not only exert the mechanical properties of fibers, but also expand the application space for the appearance and structure of fiber braids. At present, this method of compounding resin and fiber braid is a processing process that first obtains fi...
