Book LECTURE NOTES ON MANUFACTURING AND PROCESSING OF COMPOSITE MATERIALS .
دكتور مهندس أسامة محمد المرضي سليمان وُلِدَ بمدينة عطبرة بالسودان في العام 1966م. حاز على دبلوم هندسة ميكانيكية من كلية الهندسة الميكانيكية – عطبرة في العام 1990م. تحصَّل أيضاً على درجة البكالوريوس في الهندسة الميكانيكية من جامعة السودان للعلوم والتكنولوجيا – الخرطوم في العام 1998م ، كما حاز على درجة الماجستير في تخصص ميكانيكا المواد من جامعة وادي النيل – عطبرة في العام 2003م ودرجة الدكتوراه من جامعة وادي النيل في العام 2017م. قام بالتدريس في العديد من الجامعات داخل السودان، بالإضافة لتأليفه لأكثر من ثلاثين كتاباً باللغة العربية ولعشرة كتب باللغة الإنجليزية بالإضافة لخمسين ورقة علمية منشورة في دور نشر ومجلات عالمية إلى جانب إشرافه على أكثر من ثلاثمائة بحث تخرج لكل من طلاب الماجستير، الدبلوم العالي، البكالوريوس، والدبلوم العام. يشغِل الآن وظيفة أستاذ مساعد بقسم الميكانيكا بكلية الهندسة والتقنية - جامعة وادي النيل. بالإضافة لعمله كاستشاري لبعض الورش الهندسية بالمنطقة الصناعية عطبرة. هذا بجانب عمله كمدير فني لمجموعة ورش الكمالي الهندسية لخراطة أعمدة المرافق واسطوانات السيارات والخراطة العامة وكبس خراطيش الهيدروليك.
There are more than 50,000 materials available to engineers for the design and manufacturing of products for various applications. These materials range from ordinary materials (e.g., copper, cast iron, brass), which have been available for several hundred years, to the more recently developed, advanced materials (e.g., composites, ceramics, and high performance steels). Due to the wide choice of materials, today’s engineers are posed with a big challenge for the right selection of a material and the right selection of a manufacturing process for an application. It is difficult to study all of these materials individually; therefore, a broad classification is
necessary for simplification and characterization.
These materials, depending on their major characteristics (e.g., stiffness, strength, density, and melting temperature), can be broadly divided into four main categories
• Metals,
• Plastics,
• Ceramics, and
• Composites.
We tend to think of the latter half of the twentieth century as the “composite age”. In some ways this is realistic and gives us a feeling of continuity from former “material based ages” such as the stone, bronze and iron ages. Certainly the last 50 years have been associated with some remarkable developments in composite materials.
Composite materials have been utilized to solve technological problems for a long time but only in the 1960s did these materials start capturing the attention of industries with the introduction of polymeric-based composites. Since then, composite materials have become common engineering materials and are designed and manufactured for various applications including automotive components, sporting goods, aerospace parts, consumer goods, and in the marine and oil industries. The growth in composite usage also came about because of increased awareness regarding product performance and increased competition in the global market for lightweight components.
Among all materials, composite materials have the potential to replace widely used steel and aluminum, and many times with better performance. Replacing steel components with composite components can save 60 to 80% in component weight, and 20 to 50% weight by replacing aluminum parts.
