Abstract:
The paper details the manufacturing processes involved in the preparation of
through-the-thickness reinforced composites via the ‘dry preform–tufting–liquid
resin injection’ route. Samples for mechanical testing were prepared by tufting
a 5 harness satin weave carbon fabric in a 3 mm × 3 mm square pitch
configuration with a commercial glass or carbon tufting thread, infusing the
reinforced preforms with liquid epoxy resin and curing them under moderate
pressure. The glass thread reinforcement increases the compression-after-impact
strength of a 3.3 mm thick carbon fabric laminate by 25%. The accompanying drop-
downs in static tensile modulus and strength of the same tufted laminate are
below 10%. The presence of tufts is also shown to result in a significant
increase in the delamination crack growth resistance of tufted double-cantilever
beam specimens and has been quantified for the case of a 6 mm thick tufted
carbon non-crimped fabric (NCF)/epoxy c
