Define a composite material. Give an example of a composite material.
举一反三
- The stratification of parent material (heterogeneous parent material) has a more complex influence on the material migration and soil fertility, compared with homogeneous parent material. The stratification of parent material will be inherited to soil.
- The main raw material of wood-based panels is wood or no-wood plant fiber material.
- Which of the following statements are correct? A: The greater the modulus, the stiffer the material. B: The stiffer the material, the higher the resistance of the material to deformation. C: The higher the magnitude of elastic modulus, the higher the magnitude of the inter-atomic bonding forces in a material. D: The higher the magnitude of elastic modulus, the lower the magnitude of the intermolecular bonding forces in a material.
- A ferromagnetic material, which is hard to magnetize and demagnetize, could be used as a computer memory material.
- Most composite materials consist of a selected or reinforcing material and a compatible resin to obtain the specific characteristics and properties desired.
