|---|---|
| 적용범위 | 1.1?This test method covers the procedure for the determination of the dry or wet (moisture conditioned) glass transition temperature (Tg) of polymer matrix composites containing high-modulus, 20 GPa (> 3 횞 106 psi), fibers using a dynamic mechanical analyzer (DMA) under flexural oscillation mode, which is a specific subset of the Dynamic Mechanical Analysis (DMA) method. 1.2?The glass transition temperature is dependent upon the physical property measured, the type of measuring apparatus and the experimental parameters used. The glass transition temperature determined by this test method (referred to as ?쏡MA Tg?? may not be the same as that reported by other measurement techniques on the same test specimen. 1.3?This test method is primarily intended for polymer matrix composites reinforced by continuous, oriented, high-modulus fibers. Other materials, such as neat resin, may require non-standard deviations from this test method to achieve meaningful results. 1.4?The values stated in SI units are standard. The values given in parentheses are non-standard mathematical conversions to common units that are provided for information only. 1.5?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
