Large-tow carbon fiber and glass fiber composite preimpregnation equipment

Abstract

The invention relates to large-tow carbon fiber and glass fiber composite preimpregnation equipment, which sequentially comprises a fiber bobbin cradle, a fiber sequencing device, a fiber thinning device, a traction device, a weft fabric unreeling device, a resin glue film generating device, a thermal compound compression roller device, a hot plate, a cooling plate, a shaping device and a finished product reeling device. The large-tow carbon fiber and glass fiber composite preimpregnation equipment is characterized in that the fiber thinning device comprises a motor, a transmission shaft, a crank slider mechanism and a spline shaft, large-tow carbon fibers are wound on the spline shaft in a vertically staggered manner, the spline shaft drives the large-tow carbon fibers to vibrate vertically and alternately so that the large-tow carbon fibers are thinned, the thermal compound compression roller device is provided with six groups of thermal compound compression rollers, the gap betweeneach two compression rollers is accurately reflected by two grating scales and adjusted by an adjustment positioning mechanism so that the needed gap is adjusted according to technological requirements, and the preimpregnation equipment is simple in operation, labor-saving and reliable in precision, and can be used for providing 500g / m2-1650g / m2 large-grammage glass fiber prepregs and carbon fiber prepregs for manufacturing wind energy blades.

Description

technical field [0001] The invention belongs to the technical field of fiber composite material processing, in particular to large tow carbon fiber and glass fiber composite material prepreg equipment. Background technique [0002] With the development of wind energy technology and the development of offshore wind power generation, the blades of wind turbines are becoming larger. Blades above 5WM must use large tow carbon fiber prepreg. This prepreg requires 750g / ㎡, and large , Heavy-duty prepreg equipment to prepare. Carbon fiber is a new composite material with excellent mechanical properties. Among carbon fibers of various specifications, large tow carbon fibers above 24K are relatively cheap, but their internal wettability is poor, and single filaments are prone to defects such as voids. Fibers appear during the forming process. The possibility of bending and ply angle misalignment increases, resulting in mechanical properties that cannot meet the structural design requ...
