Materials CharacterizationBase element knowledge. Through years of testing and development, we have accumulated a comprehensive database of material properties. In-depth understanding of materials and processes forms the foundation of our composites expertise. Our material testing meets ASTM and SAE standards. Tension and compression Shear Impact Flexure Fatigue Glass transition temperature (Tg) Adhesive and joint characterization Test results are inputs for Multimatic’s designs and predictive models.
