GB/T 1040.5-2008Plastics -- Determination of tensile properties -- Part 5: Test conditions for unidirectional fibre-reinforced plastic composites (English PDF)

Foreword

GB/T 1040 "Determination of tensile properties of plastics" is divided into five parts.

--- Part 1. General;

--- Part 2. Test plastics molding and extrusion conditions;

--- Part 3. Test conditions for films and sheets;

--- Part 4. isotropic and orthotropic fiber-reinforced composite material of the test conditions;

--- Part 5. Test conditions for unidirectional fiber reinforced composites.

This section GB/T 1040 Part 5, ISO 527-5 identical with. Determination of "Tensile Properties of Plastics --- 1997 --- 5 Part I. Test conditions for unidirectional fiber reinforced composites. " for ease of use, this section made the following editorial changes.

--- To the "international standards" be replaced by the "Standard" or "GB/T 1040", the "this part of ISO 527" to "GB/T 1040 this part of "or" this part ";

--- Increasing the foreword of national standards in this section;

--- National Standards of the "Normative references" in which the two international standards stated in a chapter with the corresponding equivalent to using the file instead;

--- Use of the decimal point "." Instead of the international standard of the decimal point "." Appendix A of this section is normative appendix, Appendix B is an informative annex.

This part is proposed by the China Petroleum and Chemical Industry Association.

This part of the National Standardization Technical Committee of plastic products and plastic resins General Methods Chapter (SAC/TC15/SC4) centralized.

This section is responsible for drafting. National Quality Supervision and Inspection Center of synthetic resin.

1 Scope

This section 1.1 GB/T 1040 in Part 1, based on the provisions of the unidirectional fiber reinforced composite material tensile properties test conditions.

1.2 See GB/T 1040.1-2006 of 1.2.

1.3 section applies to unidirectional fiber-reinforced, and meet GB/T 1040 this part of the test requirements (including failure mode) all poly Composites thereof.

This section applies to a composite material with a thermoplastic material or thermoset materials, including prepregs (prepregs). Involved Reinforcing material comprises carbon fiber, glass fiber, aramide fiber, or other similar fibers. Related to the geometry of the reinforcing material, including single to (ie, fully in a straight line) fiber, roving and unidirectional fabrics and narrow fabrics.

This section does not apply to a composite of several unidirectional laminates in different angles multidirectional composites (see GB/T 1040.4-

2006).

1.4 part should use two different types of samples in a sample depends on the type of stress applied to the fiber direction related to the direction of (See Chapter 6).

1.5 See GB/T 1040.1-2006 of 1.5.
