发明名称 Vacuum-supported prepreg infusion hybrid method with quick hardening
摘要 <p>The method involves pressing two component regions together to a common component, where the component regions are made of a pre-impregnated prepreg-material and a dry fiber structure, respectively. The common component is vacuumed, and is heated at a heating rate of 5 Kelvin per minute up to infusion temperature of a matrix material. The infusion-compliant matrix material is infiltrated, and the common component is heated to curing temperature at the heating rate of 5 Kelvin per minute. The curing temperature is maintained for a freely adjustable curing period.</p>
