Method for modification of glass fiber composite material by ultralow temperature treatment

Abstract

The invention provides a method for modification of a glass fiber composite material by ultralow temperature treatment. The method is characterized in that it specifically includes the steps of: placing a glass fiber composite material sample in ultralow temperature treatment equipment with a cryogenic medium, sealing the container to conduct ultralow temperature treatment at constant temperature ranging from minus 100DEG C to minus 200DEG C for 1-15h; and at the end of the ultralow temperature treatment, raising the temperature through temperature programming, or taking the sample out of the ultralow temperature treatment equipment to perform natural temperature return. The glass fiber composite material treated by ultralow temperature in the invention has improved bending resistance, tensile properties, interlaminar shear performance and wear resistance, and more excellent comprehensive performance, and can meet the application demands of different fields. At the same time, the service life of the glass fiber composite material is prolonged.

AI Technical Summary

Benefits of technology

This patented technology describes modifying treatments that improve the strength or durability of materials used in construction applications such as high-strength fibers (HF). By applying specific types of chemical agents onto these surfaces before they are modified during manufacturing, better results may be achieved over traditional methods like heat setting techniques. Additionally, this new technique allows for easy handling without causing damage to fragility components while maintaining their original shape when applied properly. Overall, it provides technical improvements to enhance mechanical coupling capabilities and reduce environmental impact associated with conventional modifications.

Problems solved by technology

This patents describes various technical problem addressed during research into developing improved interfaces between different components made up of glass (G), ceramics, polymerizable substances like epoxy). These modifications can be achieved via modifying surfaces chemically or physicochemically without damaging them themselves. Existing techniques such as couplanting agents have limitations due to complexity involved in controlling processes. Ultrasound surface treatments provide advantages over existing technologies because they allow for better stability and durable behavior at elevated temperatures compared to current options.
