Solution Overview
Problem
The existing methods for manufacturing composite material components for turbomachinery, such as gas turbine blades, face challenges in increasing the initial level of damage without altering the chemical formulation of the resin, which is time-consuming and costly, and often compromises other resin properties like temperature resistance.
Innovation Solution
A process involving multilayer three-dimensional weaving of carbon fibers with the addition of carbon nanoparticles during the weaving process, which reinforces the resin without changing its chemical formulation, ensuring the nanoparticles are evenly distributed around the fibers to enhance the material's initial damage tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the chemical formulation of the resin is modified to increase the initial level of damage, then the service life of the component is extended, but the characterization process becomes time-consuming and costly, and other resin properties (temperature resistance, etc.) are compromised
Solution Approach 1:
Carbon nanoparticles are sprayed onto the carbon fibers during the weaving process, before the resin injection step. This preliminary reinforcement of the fiber structure allows the resin to better adhere and distribute, increasing the initial damage level without requiring extensive post-manufacturing characterization to optimize resin formulation
Solution Approach 2:
The invention creates a hybrid composite structure by combining carbon fibers with carbon nanoparticles. The nanoparticles are dispersed on the fiber surface during weaving, creating a multi-scale composite that enhances the resin-fiber interface and increases initial damage tolerance without modifying the resin's chemical composition or requiring re-characterization of temperature resistance properties
2Strength
If the chemical formulation of the resin is modified to increase the initial level of damage, then the component can be designed with a higher loading level, but other properties of the resin (temperature resistance, etc.) are compromised
Solution Approach 1:
Carbon nanoparticles are applied locally to the carbon fibers during the weaving process, specifically targeting the fiber surface where resin-fiber adhesion occurs. This localized reinforcement enhances the interface bonding and initial damage tolerance without requiring global modification of the resin's chemical formulation, thereby preserving the resin's temperature resistance and other bulk properties
Solution Approach 2:
The invention creates a hybrid composite structure by combining carbon fibers with carbon nanoparticles. The nanoparticles are dispersed on the fiber surface during weaving, creating a multi-scale composite that enhances the resin-fiber interface and increases initial damage tolerance without modifying the resin's chemical composition or requiring re-characterization of temperature resistance properties
3Reliability
If carbon nanoparticles are added to reinforce the resin, then the initial damage tolerance is increased, but the process complexity increases
Solution Approach 1:
The spraying of carbon nanoparticles onto the carbon fibers is integrated into the existing weaving process. The spraying device is positioned within the loom, and nanoparticles are deposited during the weaving operation itself, merging two processes (weaving and nanoparticle application) into one unified operation. This eliminates the need for separate nanoparticle application steps and reduces overall process complexity
Solution Approach 2:
The weaving loom is designed to perform multiple functions: it weaves the carbon fiber structure and simultaneously sprays carbon nanoparticles onto the fibers. This multi-functional approach consolidates equipment requirements and simplifies the manufacturing process while achieving both structural weaving and nanoparticle reinforcement in a single operation
