Foreword

This standard was drafted in accordance with GB/T 1.1-2009 rules. This standard uses redrafted Law Amendment uses ISO 11566.1996 "carbon fiber monofilament sample Determination of tensile properties." This standard and ISO 11566.1996 technical differences and the reasons are as follows. --- Because of multifilament, raw silk, the definition of tow easily cause confusion in the scope of Chapter 1, multifilament, raw silk, collectively referred to as continuous fiber tow; --- Because the ISO 291. 1977 has been repealed, ISO 10618 is not referenced in the standard, remove the ISO 11566.1996 is Chapter 2 normative references in ISO 291. 1977 and ISO 10618; --- Because quoted some fiber reinforced plastics terminology, Chapter 2, normative references added GB/T 3961-2009 fiber Reinforced plastics; --- Temperature and humidity affect the test results, combined with China's actual climatic conditions, are specified to be 7.1 at a temperature of (23 ± 2) ℃, relative Humidity of (50 ± 10)% of standard test environment, and increased non-standard environments; --- Because GB/T 29762 "carbon fiber diameter and fiber cross-sectional area measurement," added "scanning electron microscopy" 7.2 also increased the "scanning electron microscopy"; --- Since the monofilament extending greater dispersion coefficient test results for the system to be more accurate determination of compliance, Annex A.1 of each slot Increase the number of slot length prepared for five. 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., Guangzhou Blonde carbon fiber Restoration Materials Development Co., National Glass Fiber Product Quality Supervision and Inspection Center. Participated in the drafting of this standard. Fiber Co., Ltd. Weihai expand. The main drafters of this standard. Xu Qi, Wang Yumei, Chen Shang, Shi Zhuo, Xu Min, Huang Ying, Fang Yunwei, Madan, Hao Zheng Tao. Determination of carbon fiber tensile properties of single strands

1 Scope

This standard specifies the test method for single strands of carbon fiber tensile properties. This method is applicable to the individual fibers of carbon fibers, continuous fibers taken from carbon fiber, staple fiber length of yarn, woven fabric, stitching and needle Fabric.

3 Definitions

GB/T 1040.1-2006 and GB/T 3961-2009 and defined the following definitions apply to this document. 3.1 System compliance K systemcompliance It indicates elongated part by the loading system and the system caused by the specimen holder. 3.2 Sample lining specimenmounting A sheet of paper with a slot, made of metal or plastic, the length of the slot corresponding to the standard at a distance from the sample. Principle 4 The monofilament sample holder on a suitable test machine, uniform stretch to destruction of the sample, --- record load-elongation curve. Calculation of tensile strength and tensile modulus and elongation curve according to the load --- monofilament cross-sectional area. Tensile elastic modulus in stress difference divided by two points corresponding to the specified strain difference at these two points may be two stress levels (Method A), or two strain levels (Method B). Strain by poor compliance correction system, cross-sectional area was measured separately. Stress and strain may be non-linear relationship, it is necessary to define the chord modulus. Method A and Method B since the position is not defined chord With, it may give different results.

5 Apparatus and materials

5.1 tensile tester Crosshead displacement constant speed, with load --- elongated recording apparatus. Precision load instruction should be higher than 1% of the measured value. ......
