The thickness-direction properties of composite materials are designed with test methods and data are accurately evaluated to ensure their safety in use. GB/T 41762 is for Developed to meet the needs of evaluating the through-thickness properties of fiber-reinforced plastic composite laminates, it is proposed to consist of two parts. --- Part 1.Direct tensile and compression tests; --- Part 2.Determination of elastic modulus, strength and Weibull size effect of carbon fiber unidirectional laminates by bending test. Both parts can evaluate through-thickness properties, but the test methods are different, part 1 uses tensile and compression test methods, part 2 Use the bending test method. This document provides a three-point bending test method to determine the thickness direction of carbon fiber reinforced plastic composite unidirectional laminates performance. Fiber reinforced plastic composite laminate thickness Determination of directional properties - Part 2.Bending test Determination of elastic modulus of carbon fiber unidirectional laminates, Intensity and Weibull Size Effects1 ScopeThis document describes the determination of through-thickness (out-of-plane) tensile strength, tensile rupture Flexural Test Method for Bad Strain and Tensile Modulus. This document applies to carbon fiber reinforced plastic composite unidirectional (UD-CFRP) laminates. In addition, due to the existence of tensile strength in the thickness direction In the size effect, the calculation of the effective volume is also described.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text.
