1. Choose the right glass fiber raw material
The quality of Fiberglass Tissue Mat is the basis for determining the strength of non-woven fabrics. Using high-quality glass fiber raw materials can provide products with higher tensile strength and tensile strength. Common types of glass fibers include E glass fiber, C glass fiber and S glass fiber, among which E glass fiber is the most commonly used type because of its good mechanical strength and high temperature resistance.
When selecting raw materials, the following aspects should be noted:
Fiber diameter and length: The finer the fiber diameter, the smaller the gap between the fibers, which can provide a more uniform strength distribution. On the other hand, glass fibers with moderate fiber length can achieve better interweaving effects during processing, further enhancing strength.
Surface treatment: Surface treatment such as fluorination and silanization can increase the adhesion of glass fibers to the matrix and improve its bonding strength with resin or other components, thereby enhancing the overall strength.
2. Optimize the laying and arrangement structure of fibers
The strength of Fiberglass Tissue Mat depends not only on the quality of a single fiber, but also on the arrangement structure of the fibers. The laying method and direction of glass fiber have a great influence on the mechanical properties of non-woven fabrics.
Directional laying: By controlling the directional arrangement of fibers, the tensile strength of non-woven fabrics can be significantly improved. Generally speaking, laying fibers along the main force direction (such as longitudinal or transverse) can enhance the tensile strength in that direction.
Multi-layer stacking: When adopting a multi-layer structure design, the overall tensile strength and tear resistance can be improved by staggering the fiber layers (such as laying at different angles). This structure can disperse the force in all directions, thereby improving the overall strength of the non-woven fabric.
Density control: The higher the density of glass fiber non-woven fabric, the stronger the degree of interweaving between fibers, and the higher the strength. By controlling the density of fibers, its tensile strength and tear resistance can be effectively improved.
3. Enhance the resin impregnation effect
Fiberglass Tissue Mat usually needs to be combined with resin or other matrix materials to improve its mechanical properties. The impregnation effect of the resin directly affects the strength of the non-woven fabric. During the production process, the type of resin, the degree of impregnation and the curing process have a great influence on the strength of the final product.
Resin selection: Selecting resin types with excellent mechanical properties and high strength, such as epoxy resin, polyester resin or styrene-based resin, can greatly improve the strength of non-woven fabrics. For example, epoxy resin has high bonding strength and can enhance the bond between the fiber and the matrix, thereby improving the overall strength of the non-woven fabric.
Resin impregnation: The resin impregnation effect depends on the surface treatment and impregnation time of the non-woven fabric. Sufficient resin impregnation can ensure that the glass fiber is evenly covered, reduce the gaps between the fibers, and improve the strength. During the production process, the permeability of the resin can be improved by adjusting the impregnation time and temperature to ensure the close bonding between the fiber and the resin.
Curing process: Curing temperature and curing time are key factors affecting the performance of the resin. During the resin curing process, the molecular chains of the resin will undergo cross-linking reactions to enhance its strength and hardness. By optimizing the curing process, such as using a suitable temperature curve, the hardness of the resin and the bonding strength between the glass fiber and the resin can be improved.
4. Control the temperature and humidity during the production process
Temperature and humidity have a significant effect on the strength of Fiberglass Tissue Mat. During the production process, controlling the appropriate temperature and humidity conditions will help improve the strength of non-woven fabrics.
Temperature control: Too high or too low temperature will affect the performance of glass fiber, especially during the resin curing process. Too low temperature may cause the resin to not be fully cured, while too high temperature may cause damage to the glass fiber. During the production process, ensure that the production environment temperature is suitable, usually need to be controlled within a certain range to ensure the best curing effect of the resin.
Humidity control: Excessive humidity may cause glass fiber to absorb moisture and affect its physical properties. Especially in the drying and pretreatment stage of glass fiber, excessive humidity may affect the laying and curing process of the fiber, and then affect the strength of the final product. Therefore, a dry environment should be ensured during the production process.
5. Adding reinforcing agents and fillers
In order to improve the strength of Fiberglass Tissue Mat, some reinforcing agents or fillers can be added during the production process. These additives can enhance the composite properties of glass fiber and further improve its strength and durability.
Reinforcement: For example, the addition of nanomaterials, carbon fibers or other high-strength fibers can effectively improve the strength of non-woven fabrics, especially when it is necessary to improve tensile strength, compressive strength or heat resistance, adding reinforcing agents can significantly improve product performance.
Filler: Fillers such as talcum powder, mineral powder, etc. can increase the density and thickness of glass fiber non-woven fabrics, thereby improving their compression and bending resistance. Reasonable filler ratio can improve the strength of non-woven fabrics and reduce costs to a certain extent.
6. Post-treatment and strengthening process
After the production of Fiberglass Tissue Mat is completed, its strength can be further enhanced through post-treatment processes.
Heat treatment: The bonding force of glass fibers can be further enhanced through appropriate heat treatment processes (such as hot pressing, hot baking, etc.). The heat treatment process can promote the cross-linking and curing of the resin, and further enhance the overall strength and stability of the glass fiber non-woven fabric.
Compaction process: By compacting the non-woven fabric, the gaps between the fibers can be reduced, the density can be increased, and the strength can be enhanced. The surface of the compacted non-woven fabric is more uniform and has better mechanical properties.
