Effect of structural parameters on the impact properties of multilayer composites from Tururi palm (Manicaria saccifera Gaertn.) fibrous material

ABSTRACT

Tururi (Manicaria saccifera Gaertn.) is a natural fibrous mesh which protects the fruits of the Amazon Ubuçu palm tree. This research targets developing natural fiber composites from Tururi fibers and characterizing their impact properties. A set of composites from Tururi fiber with different construction parameters (number of layers, fiber orientation, and fiber volume fraction) were manufactured. The results indicated that increasing the number of layers significantly increased the impact resistance up to a limit after which the resin penetration is impaired; moreover, stretching the preform significantly reduced the fiber volume fraction, and hence the impact properties. Finally, the fiber orientation had a negligible effect on the impact energy; yet, it had a significant effect on the failure mechanism.

摘要

Tururi（MaigiasascCiviaGalttn.）是一种天然的纤维网，保护亚马逊熊果树的果实。本研究的目标是开发Tururi纤维的天然纤维复合材料并表征其冲击性能。制备了一套具有不同结构参数（层数、纤维取向和纤维体积分数）的Tururi纤维复合材料。结果表明，增加层的数量显著地增加了耐冲击性，达到极限后树脂渗透受到损害，而且，拉伸预成型体显著地降低了纤维体积分数，从而降低了冲击性能。最后，纤维取向对冲击能具有不可忽略的影响，但对破坏机理有显著影响。
