HexPly® M79 low temperature curing prepreg
今年新推出HexPly® M79is a low temperature curing prepreg for large structures, such as wind turbine blades and boat structures. The prepreg cures much more quickly than products currently on the market – saving energy and increasing output. A number of cure cycle options are possible, including a very low temperature cure of 8-10 hours at just 70°C or a more rapid cure cycle of 4-6 hours at 80°C. This is a significant time-saving on established industry prepregs where a typical cure cycle for an 80°C curing resin matrix is 10 hours.
与传统的风能预防相比,放热反应的风险也降低了60% - 但是,新系统基于标准的环氧化学,该化学具有超过20年的风叶片性能。另一个好处是至少两个月的室温下寿命很长,对于这种低温固化产品来说是不寻常的。
Hexply®M79的低温治疗使其与用于输注加工的液体环氧树脂兼容。这意味着可以在单个风叶片结构中组合预处理和输注,从而优化两种技术的好处,以从具有成本效益的处理中获得更强的层压板。
Primetex®无含碳纤维织物
Primetex®是Hexcel的专利碳纤维编织技术,在该技术中,纤维在经线和纬线方向上均散布,以产生均匀的编织和无间隙的饰面。与传统的织造过程相比,Primetex®扩散过程将织物中的闭合因子增加了5-8%(取决于碳和FAW)。
The PrimeTex® spreading process also produces thinner fabrics, resulting in greater weight savings – and the new Very Light Weight PrimeTex®, at 98g/m2, can lower the mass in a composite structure even further. Laminates made with PrimeTex® have reduced porosity, leading to better mechanical performance and when used in sandwich structures the thin PrimeTex® skins have particularly high resistance to water ingress.
在Hexcel的Composites上,Europe将是Fischer制造的滑雪棒和曲棍球棒,它使用Primetex®从高性能的双属性和非常有吸引力的饰面中受益。
Primetex®is also used to great effect in the contoured roof of the new BMW M6 Gran Coupe - combining elegant design with luxurious appearance. BMW claims on their website that the contoured roof effectively lowers the weight and centre of gravity of the M6 Gran Coupe for even better driving characteristics.
HexTOOL® Machinable Composite Tooling Material
六角HexTOOL®composite tooling material has been chosen by Lamiflex to manufacture a controlled temperature mould for the RTM processing of complex shaped frames and other structures.
之所以选择Hextool®,是因为其可加工性使LamiFlex可以轻松地集成电阻和传感器,以在模具内进行加热和温度调节。树脂入口和出口区域,用于居中销的空气提取通风口和孔也很容易在所需位置进行钻孔或加工。
Hextool®模具提供了许多好处,包括改进的热性能,生产到紧密的公差,重量比金属工具低得多,以及可修改的模具表面,可以修复或适应设计变化。
在模具Lamiflex中由RTM产生多个零件后,指出Hextool®具有很高的工具尺寸稳定性,出色的真空完整性和耐用性,同时易于维护。
Hexply®M81高TG预备
欧洲复合材料的Hexcel促进的另一个新发展是HexPly® M81– a very tough prepreg with a high Tg [glass transition temperature – the temperature above which properties start to deteriorate].HexPly® M81was developed for structural parts requiring very high mechanical strength. Suitable for cure temperatures ranging from 135°C to 180°C, the resulting cured laminates provide very high mechanical properties at service temperatures above 200°C.
Available with woven or unidirectional reinforcements, the prepreg can be cured by autoclave or press processes. Typical applications for HexPly® M81 are high strength car structures and sports equipment including performance bike wheels.
