Impact Strength and Flexural Properties of Laminated Plastics at High and Low Temperatures

Abstract

Izod-impact strength and flexural properties of unsaturated-polyester laminates reinforced with glass fabric end of phenolic laminates reinforced with asbestos fabric, high-strength paper, rayon or cotton fabric were determined at temperatures from -70 to 200 deg F. Impact strength of specimens tested flatwise at 77 deg F was 4 to 7 ft/lb per in of notch for all laminates, except those of glass fabric and rayon fabric. Flexural strengths and moduli of elasticity of all materials increased with change in test temperature. At 200 deg F, all materials, except asbestos fabric laminate, lost 30 to 40% of their flexural strength.
