Interlaminar Shear

A modified test fixture to measure the shear properties of composite laminates was designed and manufactured based upon Iosipescu shear test method. Tests on interlaminar shear propertis of T300/BMI composite laminates were conducted according to ASTM D 5379 test standard. Interlaminar shear stress/strain curves and shear failure modes were obtained. The test results showed that the modified shear test fixture and test method were effective in measuring the shear properties of composite laminates.

Environmental Barrier

The cohesive strengths of environmental barrier coatings applied to silicon carbide substrates were characterized using a compression test containing a strip of coating along a portion of the gage length. The substrate sample design and test fixture are similar to that described in ASTM D 695-96. The theory needed to extract the cohesive/adhesive strengths from the data is presented. The results of the compression tests are compared to the standard test method for the determination of the cohesive/adhesive strengths by the tension-adhesion test (TAT) (ASTM C 633-79). The preliminary results indicate that the onset of failure in the compression tests can be correlated with TAT test results, allowing for the extraction of the cohesive strength of the coating. For this system, this strength was found to be 15–20 MPa. The compression test has the advantage that it can be conducted at elevated temperature without the use of adhesives and, furthermore, is not limited by the adhesive strengths of polymeric adhesives.

A new compression test fixture was designed in the present work to study the damage tolerance of composite laminates with surface cracks or notches. The compression failure behaviors of CCF300/5228A quasi-isotropic composite laminates with prefabricated surface cracks were studied experimentally. Through the size design of the test fixture and specimens and an application of a simple test method, the complex crack growth process was captured. The experimental results showed that the compression failure modes were mainly affected by crack angles and depths, and there were two typical failure modes, which were local intra- and inter-laminar damage propagating from the crack tips and delamination growth induced from the crack leading edge. This study verified the validity of the test fixture and test method, and revealed the compression failure mechanisms of composite laminates with surface cracks.
