Background technique
Composite wind turbine blade is the critical component of wind-power generating system, directly affects the performance of whole system.Girder cap (claiming again crossbeam) is the main load parts of blade, is the product of a kind of large scale, large thickness, conventionally extends along the longitudinal length of fan blade, and its Design and manufacture quality level is very important.The material and technology that blade girder cap extensively adopts is at present mainly that glass fibre stitch bonded fabric strengthens polymer matrix composites and vacuum suction technique (vacuum resin infusion).In recent years, along with wind-driven generator is to high-power and/or low velocity wind field direction development, fan blade length constantly increases, more the carbon fiber composite fan blade of light high performance has been more preferably to select, blade girder cap is the first-selected application site of carbon fiber in composite wind turbine blade, as US5617807 (A), CN101749173A, CN101539116A, US2010104447 (A1), CN102465826 etc.
In glass fiber compound material girder cap forming technological development selection course, the reason of (be that vacuum bag is pressed) high deficiency of impregnation process quality requirement in view of monofilament prepreg overall cost (as the preparation of monofilament prepreg, low-temperature storage and low-temperature transport and paving Environmental Conditions factor etc.) in monofilament prepreg low pressure molding technique is high, paving processing quality requires high and low pressure, at present blade with glass fiber compound material girder cap extensively the material technology of employing be mainly glass fibre stitch bonded fabric resin vacuum suction technique.Although patent CN101749173A has mentioned carbon fiber composite girder cap and can adopt prepreg technique or the manufacture of resin injection technique, but in prior art, carbon fiber composite girder cap or the general monofilament prepreg technique (prepreg molding) that adopts are manufactured, as CN101526070A, CN200910028100.4, CN200910028101.9 etc.Its reason be mainly due to glass fibre comparison, it is larger that carbon fiber more carefully, effectively floods difficulty, while adopting traditional vacuum suction technique and resin system thereof to manufacture the carbon fiber girder cap of the large thickness of large scale, its dipping combination process effect and quality (being mainly mechanical property) are generally not good.Blade girder cap vacuum suction technique is bisphenol A epoxide resin system by epoxy-resin systems main body at present, be generally the bisphenol A epoxide resin system of adding thinner, or so-called " latency " low viscosity epoxy resin system (resin system viscosity further being reduced by the method that improves technological operation temperature).
Taking 3TEX company, GEC(global energy concept company) and TPI company etc. improve as the structural type aspect that the company of representative attempts from strengthening fabric, its scheme is substantially all to adopt carbon fibers/fiberglass to mix triaxial fabric (as the UniGirderTM fabric of 3TEX company exploitation etc.) to replace carbon fiber loop bonding one-way fabric, to reach the object that improves vacuum suction process resin system perfusion impregnating speed, avoids producing the defects such as dry spot.Result of study shows, although adopt special carbon fiber stitch bonded fabric, while adopting traditional vacuum absorbing process, resin easily pours into, and owing to being limited by the constraint of woven fabric structure, the performance of its composite material is restricted, and especially compression strength is poor.
Visible, although causing already, the vacuum suction technique of carbon fiber composite girder cap pays close attention to and research, current material and vacuum suction technique are also difficult to obtain high performance carbon fiber girder cap.
