Introduction
1. Background and significance of standard formulation
GB/T 43308-2023 "Glass Fiber Reinforced Thermoplastic Unidirectional Prepreg" is a comprehensive upgrade based on the original standard, aiming to meet the rapid development needs of the composite materials industry. The standard was formulated by the National Glass Fiber Standardization Technical Committee and widely absorbed the opinions of experts inside and outside the industry to ensure its scientificity and practicality.
2. Standard framework and key technical indicators
| Technical requirements | Specific provisions | New or revised content |
|---|---|---|
| Classification of matrix resins | Polypropylene (PP), polyethylene (PE), polyamide (PA), etc. | Add compatibility requirements for other matrix resins |
| Mechanical property grades | Ordinary type (C), high-strength type (T), high modulus (M), high-strength and high modulus (TM) | Add the high-strength and high modulus (TM) category to meet the needs of high-end applications |
| Universal mass deviation | ±5% | Unchanged, but the testing method is more stringent |
3. Analysis of the technical evolution of the standard
Compared with the old standard, GB/T 43308-2023 has achieved technological breakthroughs in the following aspects:
- Improved material performance: A new high-strength and high-modulus (TM) product category has been added, which is suitable for aerospace, high-end manufacturing and other fields.
- Optimized testing methods: The determination steps of the glass fiber mass fraction have been refined to ensure data accuracy.
- Enhanced environmental protection requirements: The control of the content of fluorine and alkali metal oxides has been strengthened to promote green production.
4. Implementation suggestions and precautions
Implementation suggestions:
- Enterprises should establish a sound quality management system to ensure that products meet standard requirements.
- Strengthen employee training, especially improving the technical capabilities of testing personnel.
- Optimize production processes and use automated equipment to improve production efficiency and product quality.
