“…Thus, the compaction process contributes to increasing the preform's fibre volume fraction [19]. The changing fibre volume fraction in return influences the permeability of the preform and consequently the infiltration and the mechanical properties of the final component [20]. To this end, compaction-relaxation-release tests with different non-crimp fabrics and two different binder systems were conducted.…”

A critical process step within the liquid composite moulding constitutes in the preforming of two‐dimensional textile material into a near‐net‐shape and load‐capable fibre structure by stamp forming. This paper presents fundamental material experiments on the shearing behaviour, bending properties and friction behaviour considering the binder quantity and forming temperature. In addition, the influence of the process time on the resulting stability of the preform is examined. The findings indicate that the quantity of the binder as well as the forming temperature and the process time have a great influence on the preform quality.

This paper describes the experimental investigation of the compaction behavior of dry single‐ply and multi‐ply fabric stacks (preforms). Utilizing four biaxial (two 0°/90° and two ±45°) and one triaxial (0°±45°) carbon fiber NCF, differing in weight (300 g/m2, 600 g/m2) and type of stitching (tricot, pillar, hybrid), the influence of compaction speed, pre‐compaction cycles, number of layers, and stacking sequence on compaction force was examined. In contrast to other studies, the area of interest is limited to 40–50% fiber volume content (FVC), which is based on current continuous preforming conditions. The results showed that higher testing speeds result in increased compaction forces. Pre‐compaction cycles (up to 8) significantly reduce (up to 69%) the required compaction forces of preforms for continuous preforming. Furthermore, at an equal total superficial density (1800 g/m2), 6‐ply preforms (300 g/m2 each ply) require 75–88% higher compaction forces than 3‐ply preforms (600 g/m2 each ply). This relation remains constant with decreasing or increasing total superficial density (ply number). Also the stacking sequence of 6‐ply preforms (300 g/m2 each ply) remarkably influences the compaction force, whereby the stitching seam pattern and their alignment (superposition) to each other were the main influencing factors.

“…If sizing becomes liquid enough to act as a lubricant, then it may modify the compaction behavior of a fabric. In the same line of thoughts, authors studied the effect of temperature on the compaction behavior of fabrics with a thermoplastic binder inserted between layers [31][32][33]. They observed that fabric compaction ability increased with temperature because the physical state of the binder changed from solid to viscous and then acted as a lubricant.…”
