AOCR058开发出碳增强型复合材料
AOC声明已经开发出一种针对碳纤维增强加固的专门树脂.
该公司解释称,该环氧乙烯基酯树脂的R058系列可创建具有特殊强度-重量比的轻质复合部件.
根据AOC公司,R058系列结合了环氧树脂的性能与不饱和聚酯树脂的处理速度.树脂是用于真空灌注和树脂传递模塑(RTM).树脂系列室温固化和化学抵抗了范围广泛的温度.
"R058系列是需要轻量级和高性能层压板的一个优秀的选择,"AOC的业务经理MikeDettre说,."他们不需要辅助硬化或高压灭菌法,这使他们比大多数纯环氧树脂的处理更快.这是高容量应用的关键."

制造商可使用Dymax胶粘剂公司的新"包含"技术,可轻松进行硫化以及硫化后粘结层检查.
根据Dymax,粘合剂的配方中加入了新的"包含"技术,并将公司的专利See-Curecolour-change和红外荧光技术,融合为了一种可光-硫化(light-curable)产品.
公司解释说,在未硫化的状态下,为了确认定位,加入了See-Cure技术的胶粘剂的配方是蓝色的.随着产品过度暴露于紫外线进行硫化,其会从蓝色过渡到无色,并提供明显的视觉确认,胶已经完全固化,并且粘合地点安全.
Dymax声明,使用红外光(Ultra-Red)技术的产品,在低强度下黑色光(365nm)发出荧光明亮的红色,在塑料上对比非常明显,发出自然荧光蓝的颜色(如PVC).这允许制造商将自动或手工质量检验来验证胶固化的完整,准确位置.Dymax目前的产品供应加入了包含新技术的多种医用粘合剂的配方.
