Tham khảo tài liệu 'composite materials handbook part 9', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | MIL-HDBK-17-4 3. MATERIALS PROPERTIES DATA GENERAL INFORMATION INTRODUCTION PURPOSE SCOPE AND ORGANIZATION OF SECTION DATA PRESENTATION FORMAT AND ORGANIZATION Manuals Electronic REINFORCEMENT PROPERTIES INTRODUCTION The following information pertains to the mechanical properties of various fiber reinforcements. These properties are based on material of varying maturity and should be considered experimental in nature. Typical values are listed for approximate rule-of-mixtures calculations but should not be used for final design purposes. These typical values are based on as-received properties and some change in properties should be anticipated as a result of the composite manufacturing process. ALUMINA FIBERS BORON FIBERS BORON CARBIDE FIBERS CARBON AND GRAPHITE FIBERS SILICON CARBIDE FIBERS STEEL FIBERS TUNGSTEN FIBERS OTHER FIBERS OTHER REINFORCEMENTS PROPERTIES OF MATRIX MATERIALS INTRODUCTION Section contains data for the properties of the neat matrix materials. These monolithic metals are not manufactured by conventional techniques such as standard forging rolling and casting operations whose properties would be found in Mil-Handbook 5 but rather are uniquely processed to mimic the processing operation which is used when making the composite. Common processing techniques for the neat matrix are hipped foil and hipped sheet. With these types of processing techniques the properties of the neat matrix should be as close as possible to those of the in-situ matrix in the composite. Note however that the reinforcement may affect the in-situ properties of the matrix due to either residual stresses 111 MIL-HDBK-17-4 and or reaction of the reinforcement and matrix and corresponding diffusion depletion of the elements in either constituent. Property data taken from the neat matrix material Section and reinforcement Section can be used with .
