Current production trends and demands for Fibre Reinforced Plastics are exceeding the capabilities of classical, recognised inspection and test methods, especially their capabilities to monitor the mass production of carbon fibre reinforced plastic parts. Novel non-destructive measurement methods to efficiently perform quality assurance within industrial mass production are required. This research is focused on a novel method to assess the properties of textile reinforcements employed in liquid composite moulding processes. This method non-destructively measures the resistance provided by semi-finished textiles to compressive deformation and fluid flow. Rather than calculating permeability using traditional methods, simple measures of injectability of textile reinforcements are determined using an air pulse applied within the stack or preform. On this basis, a simple, mobile prototype device has been developed to support production and quality control to evaluate the injectability and compressibility properties of stacks and preforms and gather information about processes and systems.

当前对纤维增强塑料的生产趋势和需求超出了传统的，公认的检查和测试方法的能力，尤其是它们监视碳纤维增强塑料零件的批量生产的能力。需要新颖的非破坏性测量方法，以在工业批量生产中有效地执行质量保证。这项研究的重点是评估液体复合成型工艺中使用的纺织品增强材料性能的新方法。这种方法无损地测量了半成品纺织品对压缩变形和流体流动的阻力。与其使用传统方法计算渗透率，不如通过在叠层或预成型坯中施加空气脉冲来确定织物增强材料可注射性的简单度量。
