摘要：Ceramic Fibre Reinforced Polymer composites are attractive materials for variousengineering applications, particularly for high temperature application such as a heat shield.In this study, Alumina/Silica based ceramic fibre reinforced phenolic resin composites filledwith different fillers such as Yttria-stabilized zirconia, microsilica and cenosphere wereprepared using traditional hand layup technique. Three different fillers were filled withphenolic resin in various filler concentrations. Mechanical characterizations such as tensileand compressive were carried out to quantify the effect of fillers on the mechanicalproperties of the filled composites. An enhancement in mechanical properties of the filledcomposites was found as concentrations of filler content increased. However, beyondcertain concentrations, further addition of the fillers showed a reduction in mechanicalproperties of the filled composites. Ablation behaviors of the filled composites wereinvestigated by oxyacetylene ablation test in terms of the linear ablation rate, mass ablationrate and back face temperature. Experimental results showed a favorable ablation resistancewith the addition of all the micro sized fillers. In comparison with microsilica filledceramic/phenolic composites, the phenolic matrix embedded with the yttria-stabilizedzirconia particles significantly improved the ablative properties of the filled composites interms of mass ablation rate and linear ablation rate but not when compared to cenospherefilled composites. The result of the mechanical and the ablation characterization of differentfillers filled composites were compared and discussed in detail.
