Download On the Use of Accelerated Test Methods for Characterization of Advanced Composite Materials Book in PDF, ePub and Kindle
A rational approach to the problem of accelerated testing for material characterization of advanced polymer matrix composites is discussed. The experimental and analytical methods provided should be viewed as a set of tools useful in the screening of material systems for long-term engineering properties in aerospace applications. Consideration is given to long-term exposure in extreme environments that include elevated temperature, reduced temperature, moisture, oxygen, and mechanical load. Analytical formulations useful for predictive models that are based on the principles of time-based superposition are presented. The need for reproducible mechanisms, indicator properties, and real-time data are outlined as well as the methodologies for determining specific aging mechanisms.Gates, Thomas S.Langley Research CenterPOLYMER MATRIX COMPOSITES; ACCELERATED LIFE TESTS; MICROSTRUCTURE; LIFE (DURABILITY); AGING (MATERIALS); MECHANICAL PROPERTIES; AEROSPACE ENGINEERING; AEROSPACE ENVIRONMENTS; RELIABILITY ANALYSIS; PERFORMANCE PREDICTION

Download Accelerated Environmental Testing of Composite Materials Book in PDF, ePub and Kindle
Composite materials are found to lose mechanical [properties?] on exposure to aircraft operating environments. This is mainly due to absorption of moisture from humid air by the matrix material. Composite materials are extensively used by the RAAF for both major structural components on thbe F/A-18 and for bonded repairs and doublers. The performance of these materials under long-term environmental exposure is an important aspect of both aircraft certification and in the understanding of how the components will age. This report provides a broad overview of environmental effects on composite materials and methods which may be used to predict their long-term behaviour. The use of accelerated testing environments in the laboratory is an attractive proposition as it enables tests to be carried out in reduced time frames. A number of accelerated testing methodologies and their implications are outlined here. Accelerated testing can be carried out with confidence if the exposure conditions are representative and the failure modes of the materials during mechanical tests reflect those seen in service.

Research on fiber-reinforced plastic composites has explored the effects of selected aqueous environments on the mechanical and physical properties of these composites. The composite materials tested were produced using the pultrusion process. Resins included in the study were polyester and vinylester. Fibers included were E-glass, carbon, and aramid. Environments considered were air, deionized water, acetic acid at two concentrations, and ammonia at two concentrations. Temperatures considered were room temperature, 50 and 80°C. Mechanical testing included tension, flexure, and short beam shear tests. Weight loss, thermogravimetric, and calorimetric measurements were made to determine whether degradation was taking place in the fiber or matrix phases of the composite. Accelerating factors for the various environments were calculated using the framework outlined in ASTM E 632, Standard Practice for Developing Accelerated Tests to Aid in the Prediction of the Service Life of Building Components and Materials. It was observed that a combination of weight loss and thermogravimetric measurements are useful in determining whether degradation in the composite is due to fiber or matrix degradation. Trends in weight loss closely parallel loss of mechanical properties in polyester/glass rods.

Download Accelerated Strength Testing of Thermoplastic Composites Book in PDF, ePub and Kindle
Constant ramp strength tests on unidirectional thermoplastic composite specimens oriented in the 90° direction were conducted at constant temperatures ranging from 149°C to 232°C. Ramp rates spanning 5 orders of magnitude were tested so that failures occurred in the range from 0.5 s to 24 h (0.5 to 100 000 MPa/sec). Below 204°C, time-temperature superposition held allowing strength at longer times to be estimated from strength tests at shorter times but higher temperatures. The data indicated that a 50% drop in strength might be expected for this material when the test time is increased by 9 orders of magnitude. The shift factors derived from compliance data applied well to the strength results.
