DEVELOPMENT OF HIGH TEMPERATURE JOINING AND THERMOMECHANICAL CHARACTERIZATION APPROACHES FOR SiC/SiC COMPOSITES

ABSTRACT

Advanced joining technologies are enabling for the fabrication of large and complex shaped silicon carbide-based ceramic and ceramic matrix composite components to be utilized in high temperature extreme environment applications. Many joining approaches are being proposed and developed. New standardized tests are needed to fully characterize joint properties and capabilities. One such test ISO-13124, was used for mechanical testing in this work. This test configuration allows for testing of joined crossbars in either a tensile or a shear stress state. The REA Bond joining approach using Si-8.5%Hf eutectic phas ealloy was used to join ceramic matrix composite and monolithic silicon carbide materials. In mechanical testing, low strengths were obtained with failures occurring in the joined substrates. Finite element analysis of the stress states revealed stresses concentrations at the edges of up to 30 times higher than the 2 MPa nominal stress for the tensile state. For the shear state, out of plane displace ments occurred.

INTRODUCTION

Silicon carbide fiber reinforced / silicon carbide matrix composites (SiC/SiC) are a class of ceramic matrix composite (CMC) materials are being developed for turbine engine applications for such components as combustor liners, shrouds, vanes, and blades1-4. These CMC components can operate at higher temperatures, require less cooling, and are lighter weight than metal components. The use of CMCs in such applications contributes to increased turbine engine fuel efficiencies, reduced emissions, and long term durability. As interest in fiber reinforced SiC-based composite materials continues to grow due to advancements in their properties, new integration technologies and testing capabilities will be critically needed.

In order to evaluate the mechanical properties of joints, standardized tests and testing capabilities are needed. One such standardized test5, BS-ISO-13124:2011, “Fine ceramics (advanced ceramics, advanced technical ceramics): Test method for interfacial bond strength of ceramic materials,” was applied for evaluation of mechanical properties of monolithic SiC and SiC/SiC materials joined to themselves. In this test, two long rectangular substrates are bonded across one another at their midsection to form an “X” shaped crossbar to provide samples for testing either in a tensile stress state or a shear stress state. Due to the need for multiple crossbars for testing and because of the uniques hape, a simple joining approach was needed for processing the joints. The authors had previously reported a diffusion bonding approach for joining SiC based materials using titanium interlayers6-7. However, such an approach needs relatively smooth surfaces and requires high applied loads from a hot press to aid in bond formation. Another joining approach, Refractory Eutectic Assisted BONDing (REABOND) was used for evaluating joints ac cording to ISO-13124. REABond uses Si-8.5Hf eutectic phase allow powder in a green tape for the joining interlayer. During joint processing, no load is needed and the eutectic phase melts to flow over the substrate surface and solidifies during cooling. REBOND has been demonstrated on the joining of SiC/SiC composites resulting dense, crack free joints that filled the contour of the rough CMC surface8.

Joining of SiC/SiC substrate s and monolithic SiC was conducted to support the mechanical test method development. Micros tructural analysis was conducted using optical microscopy and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) to evaluate bond quality. Mechanical tests were conducted at room temperature according to ISO-13124 for testing joints under tensile or shear stress conditions.

In correl ation to the experimental tests, the test standard was evaluated in a finite element model investigation. The purpose of the investigation was to determine the reliability of the interfacial bond strength test for two types of test methods for the ISO-13124, by characterizing the stress state within the bond region by finite element methods. The objective was to determine the stress concentration within the bond region so that a more accurate stress me asure ment can be determined from the experimental test results of the tensile and shear specimens. Knowing this stress state would better characte rize the strength of the ceramic bond and would he lp determine if any modifications were needed to the specimen and/or test setup while still remaining compliant to the ISO-13124 standard for fine and advance ceramics interfacial bond strength test method.

EXPERIMENTAL

The CMCs were two different types of silicon carbide fiber/silicon carbide matrix (SiC/SiC) CMCs. The first CMC was SiC/SiC HiPerCompTM Gen II by GE Energy (Newark, DE). The SiC fibers were Hi-Nicalon Type-S. The SiC matrix was manufactured by the prepreg melt infiltration method9. The second CMC was melt infiltrated (MI) SiC/SiC fabricated by Goodrich Corporation (CA) using Hi -Nicalon SiC fibers with a BN/SiC interface. Both Si C/Si C materials had a 0°/90° woven fiber tow architecture. Due to lower than expected mechanical strength results from the joined CMC materials, joining of monolithic SiC substrates was also conducted. The purpose was to eliminate the added complicati on of low interlaminar properties which are typical of CMCs.

REABond green tapes were prepare d for use as the interlayer for joining. Previously several eutectic phase alloys were evaluated and the Si-8.5Hf eutectic phase alloy was down-selected as giving the best results for joining CMCs8
