| Abstract: | Woven biofibre is an alternative to glass fibre as reinforcement for the thermosetting matrices, but a lack of knowledge about deformation behaviour often inhabits the development of new applications. Previous researchers have studied woven biofibre reinforcements, but little is known about the influence of the level of twist spun into the yarns. Four types of yarns were made from flax sliver (Linum usitatissimum) as reinforcements in composites that are the twist-less yarn (TLY) which is a commercial yarn structure, but one not commonly used, and as far as the authors are aware not used for reinforcement within composites. Fibres in this structure lie relatively parallel to each other and the yarns linear axis. This is the yarnstructure that maybe reffered to as a unidirectional yarn, as it is the closest structure to that of a glass roving. Second, is the conventional two fold-yarn (2FY which is a conventional yarn structure where singles yarns are made with a twist in one direction and then two of these yarns are combined with twist in the opposite direction. Third, is the high-twist singles yarn (HTS) where this is a conventional yarn structure where a continous stream of fibre is twisted to form a yarn, but the twist level is higher than what would normally be inserted into a weaving yarn. Fourth, is the medium-twist singles yarn (MTS) which is the same as the other single yarn, except that the level of twist is normal for a conventional weaving yarn. Flexural, compressive and tensile properties of the epoxy composites were compared. |
