在制作1:1大型飞机模型时，选材是至关重要的，常见的有以下几种材料：

　　When making a 1:1 large aircraft model, material selection is crucial, and the following materials are commonly used:

　　一、金属材料

　　1、 Metal materials

　　合金材料：质感好、细节表现力强，且具有一定的坚固性，适合长期保存和展示，适用于制作需要承受较大应力的模型部件，如机翼、机身框架等。

　　Alloy material: with good texture, strong detail expression, and certain robustness, suitable for long-term storage and display, suitable for making model components that need to withstand high stress, such as wings, fuselage frames, etc.

　　二、木质材料

　　2、 Wooden materials

　　桐木：比重轻、相对强度大、变形小、容易加工，是做航模的好材料。翼肋、蒙板、腹板、机身后段等零件可选桐木。

　　Tongmu: It has a light weight, high relative strength, small deformation, and is easy to process, making it a good material for making airplane models. Components such as wing ribs, cladding, belly plates, and rear fuselage sections can be made of paulownia wood.

　　松木：纹理均匀、木质细密、比重较轻、不易变形、易于加工并富有一定的弹性，主要用于航模中的受力件，如翼梁、发动机架、操纵机构的底座等。

　　Pine wood: with uniform texture, fine wood, light weight, not easy to deform, easy to process and rich in elasticity, mainly used for load-bearing parts in aircraft models, such as wing beams, engine frames, and the base of control mechanisms.

　　榉木：材质坚硬、质量沉重、抗冲击力好、纹理均匀紧密，是做螺旋桨的好材料。

　　Beech wood: Made of hard material, heavy weight, good impact resistance, uniform and tight texture, it is a good material for making propellers.

　　椴木：纹理非常均匀细腻平直、具有较大的韧性、容易加工，是制作实体像真模型的好材料，可用于硬壳机身（如竞速模型机身）、螺旋桨和发动机架等。

　　Limewood: With a very uniform, delicate, and straight texture, it has great toughness and is easy to process. It is a good material for making solid and realistic models, and can be used for hard shell bodies (such as racing model bodies), propellers, and engine mounts.

　　层板：有良好的耐水、耐气候和高力学性能，强度很好。常用的有航空层板、椴木层板及精制层板（又称木材层积塑料），其中航空层板用途最广，可作强度很大的蒙板、翼根部的翼肋、隔框和加强片等。

　　Laminated board: It has good water resistance, weather resistance, and high mechanical properties, with excellent strength. Commonly used are aviation laminated boards, oak laminated boards, and refined laminated boards (also known as wood laminated plastics), among which aviation laminated boards are the most widely used and can be used as high-strength masks, wing ribs at the base of wings, frames, and reinforcing sheets.

　　三、塑料材料

　　3、 Plastic materials

　　塑料板：易裁剪成型，成本低、便于塑形和上色，但强度和耐久性可能不如合金和木质材料，适合初学者制作或用于装饰性较强的部件。

　　Plastic board: easy to cut and shape, low cost, easy to shape and color, but its strength and durability may not be as good as alloys and wooden materials, suitable for beginners to make or for decorative parts.

　　ABS塑料：加工方便，成本相对较低，适合大规模生产。

　　ABS plastic: easy to process, relatively low cost, suitable for large-scale production.

　　透明塑料或亚克力材料：驾驶舱玻璃等透明部件常使用此类材料，具有良好的透明度和耐冲击性，能够清晰地展示内部结构。

　　Transparent plastic or acrylic materials: These materials are commonly used for transparent components such as cockpit glass, which have good transparency and impact resistance, and can clearly display the internal structure.

　　四、其他材料

　　4、 Other materials

　　kt板：质轻且易裁剪成型，配合碳纤维杆等增强材料可以增加强度。

　　KT board: lightweight and easy to cut into shape, combined with reinforcing materials such as carbon fiber rods to increase strength.

　　橡胶或塑料材料：可用于制作起落架的轮胎。

　　Rubber or plastic materials: can be used to make tires for landing gear.

　　胶水、强力胶等粘贴材料：用于固定和组装模型部件。

　　Adhesive materials such as glue and strong glue: used to fix and assemble model components.

　　在实际制作中，可以根据具体需求和预算选择合适的材料。例如，对于需要承受较大应力的部件，可以选择合金材料；对于装饰性较强的部件，则可以选择木质或塑料材料。同时，也需要注意材料的加工性能和可塑性，以确保制作出的模型具有高精度和逼真的外观。

　　In actual production, suitable materials can be selected based on specific needs and budget. For components that require significant stress, alloy materials can be chosen; For decorative components, wood or plastic materials can be chosen. At the same time, attention should also be paid to the processing performance and plasticity of materials to ensure that the produced model has high precision and realistic appearance.
