Highly aligned flax/polypropylene nonwoven preforms for thermoplastic composites
چکیده انگلیسی

A major challenge for natural fibre composites is to achieve high mechanical performance at a competitive price. Composites constructed from unidirectional yarns and woven fabrics are known to perform significantly better than composites made from random nonwoven mats, but unidirectional yarns and fabrics are much more expensive to manufacture than random nonwoven mats. Here, we report on highly aligned natural fibre nonwoven mats that can be used as a replacement for unidirectional woven fabrics. A drawing operation is added to the conventional nonwoven process to improve fibre alignment in the nonwoven preforms and the final composites. The modified nonwoven manufacturing process is much simpler and cheaper than the unidirectional woven fabric process because of the elimination of expensive spinning and weaving operations. The composites fabricated from the highly aligned nonwoven mats showed similar mechanical strength as the composites made from unidirectional woven fabrics.


► We report a manufacturing process for unidirectional natural fibre mats.
► Spinning and weaving operations are omitted to reduce cost.
► The UD mats have a similar fibre orientation factor as UD woven fabrics.
► The UD mats provide similar composite mechanical strength as UD woven fabrics.
