GB/T 14208.3-2009Textile-glass-reinforced plastics -- Determination of mechanical properties on rods made of roving-reinforced resin -- Part 3: Determination of compressive strength (English PDF)

Foreword

GB/T 14208 "glass fiber reinforced plastic roving - reinforced resin rod measuring mechanical properties" is divided into four parts.

--- Part 1. General considerations and preparation of rods;

--- Part 2. Determination of flexural strength;

--- Part 3. Determination of compression strength;

--- Part 4. apparent interlaminar shear strength was measured.

This section GB/T 14208 Part 3, this part identical with ISO 3597-3:2003 "woven glass fiber reinforced plastic Material roving reinforced resin - Part 3 Determination of mechanical properties on rods. Determination of strength "(in English) compression.

This section is equivalent translation ISO 3597-3:2003, identical in technical content.

For ease of use, this section made the following editorial changes.

a) to the "international standards" to the "standard" to "this part of ISO 3597" with the words "GB/T 14208 this part" or "the section";

b) Remove the preface international standards;

c) increase the national standard foreword;

d) the "Normative references" international standards with the corresponding equivalent international standards in place of national standards listed chapter.

This Part replaces GB/T 14209-1993 "textile glass fiber roving rod composites - Determination of compressive strength." Section compared with the GB/T 14209-1993 The main changes are as follows.

--- Preparation of rods relevant details in GB/T 14208.1 is given, remove the GB/T 14209-1993 stick prepared contents;

--- Sample measurement accuracy by a 0.01mm to 0.1mm;

--- Increased destruction of the sample type.

This part is proposed by the China Building Materials Federation.

The fiber-reinforced plastic part by the National Standardization Technical Committee (SAC/TC39) centralized.

1 Scope

GB/T 14208 in this part of the provisions of the circular cross-section made of roving-reinforced resin rod (hereinafter referred to as stick) Determination of compressive strength. test Stick to the original sample (untreated) or handle bars for some time in boiling water (or other medium).

This section applies to the inspection and quality control of glass fiber rovings, assess matching glass fiber rovings and resin system.

Test results can not be used as design data.

4 Sample preparation and conditioning

The ends should be parallel and perpendicular to the axis of the specimen. When the specimen diameter of 6mm, the sample length is 22.5mm.

Where.

Each type of test (untreated sample and the sample treated) requires at least eight samples; consensus by the parties concerned, for GB/T 14208.3-2009/ISO 3597-3:2003
