Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 18370-2001 "fiberglass roving." This standard and GB/T 18370-2001 main technical difference. --- E-glass fibers to E glass fibers, increased ECR glass fiber roving category (see Chapter 3); --- Remove the fabric tensile breaking strength requirements (see the 2001 edition 5.6); --- Increased laminate tensile strength, tensile modulus and flexural modulus of the requirements (see 4.6.1); --- Modify the bending strength requirements laminates (see 4.6.1 and 462, 2001 edition 5.7.); --- Fabric appearance quality is determined by a scoring method to the point system, and revised requirements (see 48, 2001 version 5.10.); --- Remove the length requirements (see the 2001 edition 5.9); --- Added Appendix A and Appendix B (see Appendix A and Appendix B). The standard proposed by China Building Materials Federation. This standard by the National Standardization Technical Committee fiberglass (SAC/TC245) centralized. This standard is drafted by. Nanjing Fiberglass Research and Design Institute Co., Ltd., Changzhou Tianma Group Co., Jiashan County of Zhejiang Province Glass fiber weaving factory, Jushi Group Co., Ltd., the national glass fiber product quality supervision and inspection center. The main drafters of this standard. Chen Jianming, Wang Yumei, Chen Shang, Fang Yunwei. This standard replaces the standards previously issued as follows. --- JC/T 281-1994, JC/T 576-1994. Fiberglass woven roving
