有关复合材料成型的更多信息

For the infusion and prepreg methods, alongside resin additives, WACKER also supplies silicone rubber grades and fabrics for the production of vacuum bags.These bags can be placed quickly and securely over the mold before each part is produced. Repeated, time-consuming sealing with conventional vacuum film is no longer necessary. Bags made with rapid-curing, two-part ELASTOSIL® silicone rubber guarantee more processing runs, fewer vapors and more flexibility.

如今，从航空、运输到消费品行业，很多应用领域如果离开了纤维增强塑料复合材料，简直无法想象。将瓦克硅橡胶及织物用于可重复使用的真空套，可改善复合树脂的灌注成型工艺。这些有机硅真空套能够在生产部件之前迅速安全地铺放在模具上面。这样，就再也不需要采用传统真空薄膜进行既重复又耗时的密封工作了。
