1. Application Development Trend Of Aircraft Composite Materials

Since Its Introduction, Advanced Composite Materials Have Been Shining In Various Aircrafts. Together With Aluminum, Steel Titanium, They Have Become The Fourth Largest Aviation Structural Material. They Have High Specific Strength Specific Modulus, Low Thermal Expansion Coefficient, Strong Fatigue Resistance Vibration Reduction Capabilities, Designable Models, Wave-Absorbing Concealed Models. They Are The Only Choice For Aircrafts. The Amount Of Composite Materials Used In Modern Advanced Aircraft Fuselage Structures Is Increasing. After Several Stages Of Development, They Have Been Applied Non-Load-Bearing Secondary Load-Bearing Components To The Main Load-Bearing Components Of The Tail, Then To The Main Load-Bearing Components Of The Wings Fuselage. This Is A Requirement For Aircraft Performance, It Is Also A Need For Commercial Success Market Competition.

Technical Requirements For Aircraft Composite Structure Repair

With The Continuous Advancement Of Science Technology, Composite Materials Have Gradually Appeared In The Aviation Field Have Been Widely Used In The Development Of Modern Aviation. Since Composite Materials Have Become An Important Part Of Modern Aircraft Structures, Their Damage Mechanism Is Different Metal Damage, The Research On Composite Material Structure Repair Technology Has Important Practical Significance. Composite Materials Generally Have Disadvantages Such As Low Interlaminar Strength, Poor Lateral Performance, Weak Compressive Resistance. Aircraft Are Very Prone To Various Structural Damages Mainly Caused By Impact Damage, Such As Cracks, Notches, Delamination Holes, Which Will Significantly Reduce The Static Dynamic Load Performance Of Composite Materials. In Severe Cases, It Will Directly Threaten The Flight Safety Of The Aircraft. With The Increasing Proportion Of Composite Materials In Aircraft Structures, The Repair Maintenance Of Composite Materials Structures Has Become Increasingly Important. It Is Necessary To Accelerate The Research Development Of Repair Materials, Continuously Absorb New Technologies, Develop Towards High Quality, High Efficiency Low Cost.

2. Application Technical Requirements Of Helicopter Composite Materials

The Use Of Advanced Composite Materials In Helicopters Can Reduce Weight Improve Crash Resistance. At Present, The Rotor System Of Domestic Helicopters Uses Advanced Composite Blades Titanium Alloy Ball-Flexible Main Rotor Hubs, The Fuselage Uses A Partial Composite Structure, With The Composite Area Accounting For 50% Of The Entire Aircraft. In The Future, The Use Of Composite Materials On Helicopters Will Reach About (70-80)%, Even All-Composite Aircraft Will Appear. Huiwen Can Perform CNC Processing On Composite Materials : CNC Turning, Milling, Drilling, Grinding, Sheet Metal Processing  Other Processes ( Precision Parts CNC Machining )

3. Composite Material Structure Technology Of Aerospace Products

Aerospace Products Use A Large Number Of Advanced Composite Materials, Such As Glass Fiber, Fiberglass, Carbon Fiber Other Products, Which Contribute To The Lightweight, Low Cost, High Heat Protection High Performance Of Missiles Rockets. Advanced Composite Materials Are Usually Used In Missile Bodies, Wings, Tail Fins, Radar Covers, Air Inlets Other Structural Components. In The Field Of Launch Vehicles, Advanced Composite Materials Can Be Used To Manufacture Solid Engine Casing Structures, Rocket Body Fairings, Instrument Cabins, Interstages, Engine Nozzle Throat Liners, Satellite Brackets, Cryogenic Tanks Other Components. The Significant Performance Advantages Potential Lightweight Capabilities Of Advanced Composite Materials Have Made Them Widely Used In The Field Of Launch Vehicles Missiles. In Order To Effectively Reduce The Weight Of Rockets Missiles Improve Combat Performance, It Is Expected That The Application Of Carbon Fiber Composite Materials In This Field Will Be Further Expanded In The Future.

4. Application Demand Of Ship Composite Materials

Composite Materials For Ships, Especially Those Used In Hull Structures, Are Mainly Polymer-Based Composite Materials. According To The Structure, They Can Be Divided Into Two Types: Laminates (Fiber-Reinforced Composite Materials) Sandwich Structure Composite Materials. They Contain Three Important Composite Materials: Reinforcing Materials, Resins (I.E., Matrix) Core Materials. Marine Composite Materials Can Be Divided Into Main Load-Bearing Structures, Secondary Load-Bearing Structures, Non-Load-Bearing Structures, Etc. According To The Load-Bearing Parts. According To The Function, They Can Be Divided Into Five Major Series Of Materials: Structure, Damping, Acoustics (Including Sound Absorption, Sound Insulation, Sound Transmission), Stealth (Including Wave Absorption, Wave Transmission, Reflection, Frequency Selection), Protection. Composite Materials Have Great Advantages In Ship Applications. Accelerating The Design Development Of Composite Materials Formulating Unified Standardized Design Standards Are The Main Problems That Hinder Their Application In Ships.

Ship Composite Materials Technology Industry Demand Development Trend

After The Opening Of The Arctic Route, Requirements Were Put Forward For The Thermal Insulation Performance Of The Ship Hull, Especially The Ship's Superstructure. Steel Plates Alone Cannot Meet The Requirements. The Use Of Composite Materials In The Ship's Superstructure Can Solve This Problem. This Can Be Industrialized. Of Course, There Are Many Technical Difficulties To Overcome Here.
