Introduction
Carbon fiber reinforced composite thin-wall pipes are widely used in aviation, aerospace, shipbuilding, automobile, sports goods and other industries due to their excellent properties such as light weight and high strength:
GB/T 43938 aims to standardize the mechanical properties test methods of this type of products and is intended to consist of two parts:
--- Part 1: Tensile test: The purpose is to further standardize the tensile test method for carbon fiber reinforced composite thin-walled pipes:
--- Part 2: Compression test: The purpose is to further standardize the compression test method for carbon fiber reinforced composite thin-walled pipes:
Mechanics of Carbon Fiber Reinforced Composite Thin-Wall Pipes
Performance test methods Part 2: Compression test
1 Scope
This document specifies the test specimens, test conditions, equipment, and test methods for the axial compression performance test of carbon fiber reinforced composite thin-walled pipes:
Steps, data processing and test report, etc:
This document is applicable to the determination of the axial direction of fiber reinforced composite thin-walled pipes with a wall thickness not exceeding 1 mm and a nominal diameter less than 50 mm:
The compressive strength and axial compressive elastic modulus can be used as a reference for other fiber reinforced composite thin-walled pipe fittings:
