Microscopic investigation of tow geometry changes in a woven prepreg material during draping and consolidation
Viewed 220 times since Wed, Jun 3, 2015
Changes in tow geometry are measured during draping and consolidation of a helmet component with 5-harness satin weave carbon fibre reinforced plastic (CFRP) prepreg. The tow microstructure is found by sectioning specimens cut from the helmet.... Read More
Intraply shearing characterization of thermoplastic composite materials in thermoforming processes
Viewed 165 times since Sat, May 14, 2016
The Continuous Fibre Reinforcements and Thermoplastic resin (CFRTP) are widely employed in the prepreg processes. Currently, the most used thermoplastic resins in aeronautics are PPS (polyphenylene sulfide) and PEEK (Polyetheretherketone). They... Read More
Deformability of Unidirectional Prepreg Materials
Viewed 173 times since Sat, May 14, 2016
To reduce cost of structural composites the development of more efficient manufacturing methods is of great interest. Sheet forming of thermoset prepreg, also known as hot drape forming, has been a promising manufacturing method for decades. An... Read More
