日前，英国预浸料供应商Composites Evolution公司开发了一款名为Evoprep EPC200的可变温固化预浸料，进一步扩展了产品系列。得益于新研制的增韧环氧树脂体系，该产品能够在65-120°C温度范围内，经真空袋、真空炉、非热压罐或模压工艺实现固化。
该公司强调，Evopreg EPC200预浸料主要为那些采用低温非热压罐模压成型工艺获得高表面光洁度的制造商而开发。这款环氧树脂预浸料拥有灵活的固化曲线，适合高温下的快速成型，在缩短生产周期的同时保持了较高的性能水平。
Composites Evolution公司的Evopreg EPC系列树脂可广泛应用于碳纤维、玻璃纤维、芳纶和天然纤维等增强体。

Composites Evolution has officially launched its new Evopreg EPC200 variable temperature cure epoxy component prepreg system.
Composites Evolution has expanded its popular Evoprep EPC component epoxy range, with the addition of a new variable temperature curing prepreg – allowing moulders to achieve a visual quality surface finish from a variety of processes at a range of temperatures.
Sales and Marketing Director Ben Hargreaves explains further; “Evopreg EPC 200 is primarily aimed at moulders using low-temperature, out-of-autoclave moulding processes, who want to produce components with an exceptional surface finish. However, it’s flexible cure profile also makes it ideally suited to rapid processing at higher temperatures, which means that the same level of performance can be achieved in just a fraction of the time.”
Evopreg EPC200 is based on a toughened epoxy resin system and is specially formulated to allow curing between 65°C and 120°C, using vacuum bag/oven, autoclave or press-moulding.
Composites Evolution’s Evopreg EPC component resins are available on a range of carbon, glass, aramid and ampliTex flax reinforcements.
