| Abstract: | The aim of this paper is to demonstrate for the first time the technological potential of novel, totally bio-based, binder-free vegetable fiber-composites based on the reed-like plant Typha sp. Binder-free vegetable fiberboards based on Cattails were prepared and their mechanical (flexural modulus of elasticity, flexural strength and water absorption) and surface textural properties were determined. The influence of press time and panel density on the properties was investigated. In contrast to currently known natural fiber composites based on hemp, flax, kenaf or the like annual plants which all require up to 30 wt% of suitable bonding resins, the typha based composites were prepared completely without the addition of any extraneous glue and showed good mechanical performance that clearly exceeded the performance of other natural fiber composites containing low percentages of phenolic binder (15%). Of special interest were the superior surface properties of the typha based panels. Despite the coarse nature of the raw fiber material and the rough texture of the typha based fiber mats, binder-free typha panels showed excellent surface smoothness which makes this novel composite material highly interesting for light-weight applications with high surface quality standards, for example, as powder-coated elements for the automotive and furniture industries. |
