a lightweight high compression strength ultra high temperature ceramic Corrugated Panel with potential for thermal protection system applications
Materials & Design, 2015Co-Authors: Rujie He, Xiangmeng Cheng, Rubing Zhang, Daining FangAbstract:Abstract ZrB 2 –SiC–graphite ultra high temperature ceramic (UHTC) Corrugated Panel was firstly proposed and fabricated with potential application for sandwich structured thermal protection system. The compression properties of the as-prepared ultra high temperature ceramic Corrugated Panel were evaluated at 1600 °C in air. The compression modulus and strength of this ultra high temperature ceramic corrugate Panel were 312 MPa and 17 MPa respectively. The design of Corrugated Panel exhibited an excellent combination of lightweight and excellent compression properties. This study would provide a novel concept of ultra high temperature ceramic Corrugated Panel for the design of ultra high temperature thermal protection system applications.

Fabrication and mechanical properties of lightweight ZrO2 ceramic Corrugated core sandwich Panels
Materials & Design, 2014Co-Authors: Rujie He, Xiangmeng Cheng, Rubing Zhang, Daining FangAbstract:Abstract ZrO 2 ceramic Corrugated core sandwich Panels were fabricated using gelcasting technique and pressureless sintering. The nominal density of the as-prepared ZrO 2 ceramic Corrugated Panel was only 2.4 g/cm 3 (42.9% of bulk ceramic). Lightweight was realized through this sandwich structured design. The three-point bending strength was measured to be 298.4 MPa. And the specific bending strength was as high as 124.3 (114% higher than bulk ceramic). The compressive strength was 20.2 MPa. High strength was also realized through this sandwich structured design. The stress distribution during three-point bending and compression testing was finally simulated using finite element analysis (FEA) method.

Acoustic Design of Lightweight Gas Turbine Enclosures
Journal of Engineering for Gas Turbines and Power-transactions of The Asme, 1991Co-Authors: R. D. RawlinsonAbstract:Acoustic enclosures for the gas turbine industry have to comply with a number of stringent safety requirements including structural strength, fire resistance, and sound insulation. This has led traditionally to heavy enclosure designs. Corrugated enclosure Panels offer significant structural advantages because of their increased bending stiffness. Consequently, a Corrugated Panel of a given thickness can give the same structural strength as a flat Panel of substantially greater weight and thickness. However, Corrugated Panels are intrinsically less effective as a sound insulator than flat Panels of the same thickness. This paper examines the implications of Corrugated, lightweight Panels for acoustic enclosures. It illustrated that, by careful design, the inherent acoustical disadvantages of Corrugated Panels can be overcome so that thinner, lighter, and more cost-effective enclosures can be used without compromising the overall structural and acoustical design requirements.

Corrugated skin in a foam core sandwich Panel
Composite Structures, 2009Co-Authors: Jack Reany, Joachim L GrenestedtAbstract:Abstract Sandwich plates with one Corrugated and one flat skin were studied with the goal to find configurations with higher strength and/or stiffness and reduced weight. A procedure for calculating homogenized orthotropic plate stiffnesses of the sandwich was developed and applied to a number of different profiles. The corrugations lead to increased bending stiffness in one direction but reduced in another. The effect on uniaxial and shear buckling was investigated, with improvements seen for certain combinations of corrugation geometry and material properties. Both conventional (flat) and Corrugated skin sandwich Panels with the size 1.34 m × 1.59 m were subsequently designed and manufactured for a hybrid ship hull specimen. The numerical analysis predicted the Corrugated Panel to be 25% stronger than the flat counterpart in spite of being 15% lighter (by numerical prediction as well as experimental weighing).
