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.
The various methods described below have been developed to reduce the resin content of the final product. As a rule of thumb, hand lay-up results in a product containing 60% resin and 40% fiber, whereas vacuum infusion gives a final product with 40% resin and 60% fiber content. The strength of the product is greatly dependent on this ratio.
Polymer Matrix Composites (PMCs) are very popular due to their low cost and simple fabrication methods. Use of non-reinforced polymers as structure materials is limited by low level of their mechanical properties, namely strength, modulus, and impact resistance. Reinforcement of polymers by strong fibrous network permits fabrication of PMCs, which is characterized: high specific strength, high specific stiffness, high fracture resistance, good abrasion resistance, good impact resistance, good corrosion resistance, good fatigue resistance and Low cost.
