Improving the temperature resistance and fatigue resistance of fiberglass can be achieved through the following methods:
1. Choose high-temperature resistant resin: The resin used in ordinary fiberglass is prone to softening at high temperatures, so high-temperature resistant resins such as phenolic resin, epoxy resin, or polyimide resin can be chosen, which can withstand higher temperatures without softening.
2. Use high-performance fibers: The strength of glass fibers will decrease at high temperatures. High performance fibers such as carbon fiber, Kevlar fiber, etc. can be considered, which have better temperature resistance and fatigue resistance.
3. Improving the distribution and arrangement of fibers: By optimizing the laying method and arrangement of fibers, the mechanical properties of fiberglass can be improved, including fatigue resistance. For example, using techniques such as staggered laying and multi-directional weaving can improve the overall performance of materials.
4. Adding fillers: Adding some high-temperature resistant fillers, such as zirconia and silica powder, can improve the heat resistance and mechanical strength of fiberglass.
5. Use high-temperature resistant curing agents and accelerators: Adding high-temperature resistant curing agents and accelerators to the resin formula can increase the crosslinking density of the resin, thereby improving its temperature resistance.
6. Surface coating: apply a layer of high temperature resistant and anti-aging coating on the glass fiber reinforced plastic surface to protect the internal materials from the impact of high temperature and ultraviolet rays, thus improving the temperature resistance and extending the service life.
7. Optimization design: By optimizing the structural design and reducing stress concentration, the fatigue resistance of fiberglass can be improved. For example, using rounded corners instead of sharp ones, increasing the size of the connecting parts, etc.
8. Heat treatment: Heat treatment of fiberglass can improve its internal structure, enhance its temperature resistance and fatigue resistance.
By using the above methods alone or in combination, the temperature resistance and fatigue resistance of fiberglass can be effectively improved, making it suitable for more demanding environments and load conditions.
