Methods for testing and improving interfacial shearing performance of fiber-resin composite under high temperature condition

Abstract

The invention discloses a method for improving the interfacial shearing performance of a fiber-resin composite under a high temperature condition. The method comprises the following steps: fully infiltrating selected fibers with at least a resin solution and then carrying out drying so as to obtain the fiber-resin composite; and coating the fiber-resin composite with resin and curing the resin. Compared with the prior art, the method provided by the invention can effectively improve the interfacial shearing performance of the porous fiber-resin composite under the high temperature condition, is simple in process, easy to operate, low in cost, convenient for large-scale implementation, and has good application prospects. The invention also discloses a testing method for the interfacial shearing performance of fiber-resin composite under the high temperature condition. The testing method has the advantages of easiness in implementation, good stability, good accuracy, etc.

AI Technical Summary

Benefits of technology

This patented testing method allows for stable and accurate evaluation of how well different materials are joined together under specific conditions during use or processing. It improves upon existing methods by making them more effective when tested at higher temperatures compared to previous designs. Additionally, this new approach simplifies the procedure while reducing costs and promotes wider applicability across various industries such as transportation, construction, energy production, etc., which may benefit from these improved properties.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the quality control during production of carbon nano tubing bundles used in structural components like aircrafts. Current solutions involve assembling these bundle elements together before curing, which may lead to aggregating issues where some parts get stuck inside each others' cavities. To address this issue, new techniques were proposed involving incorporated small particles called quantum dots instead of single crystal ones, but current approaches face challenges including difficulty achieving even distribution within the composition while maintaining good cohesion behavior.
