Standard Test Method for Measuring the Curved Beam Strength of a Fiber-Reinforced Polymer-Matrix Composite
|Publication Date:||10 May 1999|
|ICS Code (Reinforced plastics):||83.120|
1.1 This test method determines the curved beam strength of a
continuous fiber-reinforced composite material using a 90° curved
beam specimen (Fig. 1). The curved beam consists of two straight legs
connected by a 90° bend with a 6.4-mm inner radius. An
1.2 This test method may also be used to measure the interlaminar tensile strength if a unidirectional specimen is used where the fibers run continuously along the legs and around the bend.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information purposes only.
