BS ISO 19927:2018规定了通过纤维增强塑料复合材料的双梁剪切（DBS）试验确定层间强度和模量的程序。该方法适用于具有热固性基体的玻璃或碳纤维增强塑料复合材料，前提是获得可接受的层间失效。本文件仅适用于具有对称和平衡铺层的层压板？避免弯曲/扭曲或弯曲/伸展耦合变形（见6.2）。首选的铺层是单向的，纤维沿试样（轴向）长度对齐。 通过试验评估试验对特定铺层、基质和纤维（如天然纤维）的适用性，以确保获得正确的分层失效。交叉引用:ISO 1268（所有部分）ISO 2602ISO 16012ISO 5893ISO 472ISO 291ISO 14130ISO 7500-1ISO 9513ASTM D3846ASTM D7078ASTM D5379ASTM D2344EN 2377EN 2563BS 4994BS 6464ISO 2818ISO 527-4:1997ISO 5725-1:1994/COR 1:1998购买本文件时可提供的所有现行修改件均包括在内。

BS ISO 19927:2018 specifies a procedure for determining the interlaminar strength, and modulus, by double beam shear (DBS) tests of fibre-reinforced plastic composites.The method is suitable for use with glass or carbon fibre-reinforced plastic composites with thermoset matrices, providing an acceptable interlaminar failure is obtained.This document only applies to laminate with a symmetrical and balanced lay?up as it avoids bending/twisting or bending/extension coupling deformations (see 6.2). The preferred lay-up is unidirectional, with fibres aligned along the specimen (axial) length.The suitability of the test for specific lay-ups, matrices and fibres (e.g. natural) are assessed by trial tests to ensure the correct delamination failures are obtained.Cross References:ISO 1268 (all parts)ISO 2602ISO 16012ISO 5893ISO 472ISO 291ISO 14130ISO 7500-1ISO 9513ASTM D3846ASTM D7078ASTM D5379ASTM D2344EN 2377EN 2563BS 4994BS 6464ISO 2818ISO 527-4:1997ISO 5725-1:1994/COR 1:1998All current amendments available at time of purchase are included with the purchase of this document.
