Forming processes of continuous fiber reinforced thermoplastic materials are oftentimes limited to high volume production due to the high costs for tooling and processing machines. This study suggests the combined use of a cold and simple tool and high forming speeds to reduce tooling and processing costs and enable the usage of common stamping machines. Half sphere samples are produced from single and two-layer polypropylene and glass fiber organo-sheets in a custom built drop tower and analyzed for their geometry, degree of re-consolidation, surface quality and potential fiber damage using a variety of microscopy techniques. While only mediocre degrees of re-consolidation and limited surface qualities can be achieved with the combination of a cold tooling and state-of-the-art forming speeds of 0–0.5 ms⁻¹, the usage of a higher forming speed of 3 ms⁻¹, vastly improves surface qualities and the degree of re-consolidation without any detectable fiber damage. This effect is more pronounced in the dual layer material. Extensive knowledge on the forming behavior of continuous fiber reinforced thermoplastics at high cooling rates and high speeds of deformation is required for sufficient process control and future studies need to further elaborate and quantify the influencing factors and limits of high-speed forming of continuous fiber reinforced thermoplastics.

由于工装和加工机器的高成本，连续纤维增强热塑性材料的成形工艺通常限于大批量生产。这项研究表明，结合使用冷，简单的模具和较高的成型速度可以降低模具和加工成本，并可以使用普通的冲压机。半球样品是在定制的滴水塔中由单层和两层聚丙烯和玻璃纤维有机片材制成的，并使用多种显微镜技术分析了它们的几何形状，重新固结度，表面质量和潜在的纤维损坏。通过冷加工和0-0.5 ms ^-1的最新成型速度只能实现中等程度的重新固结和有限的表面质量例如，使用3 ms ^-1的较高成形速度，可极大地改善表面质量和重新固结程度，而不会检测到任何纤维损坏。这种效果在双层材料中更加明显。需要足够的有关连续纤维增强热塑性塑料在高冷却速率和高变形速度下的成型行为的广泛知识，以进行充分的过程控制，并且未来的研究需要进一步阐述和量化影响连续纤维增强热塑性塑料高速成型的因素和限制。 。
