Previous work has established the feasibility of producing acrylic denture bases reinforced with layers of highly drawn linear polyethylene fibres in a woven form. This paper reports on the mechanical properties of the system, including the effect of water conditioning. It is confirmed that substantial improvements in impact strength can be obtained by the incorporation of the polyethylene fibres in woven form. The fibre/resin integration within the dentures has also been studied by optical microscopy. It was found that delamination may occur during some processing stages and steps are suggested to avoid this problem.
先前的研究已经证实了生产以编织形式的高度拉伸线性聚乙烯纤维层增强的丙烯酸义齿基托的可行性。本文报道了该系统的力学性能，包括水调节的影响。证实通过加入编织形式的聚乙烯纤维可以显著提高冲击强度。还通过光学显微镜研究了义齿内纤维与树脂的结合情况。发现分层可能在某些加工阶段发生，并提出了避免该问题的措施。
