Chpt 2 Composite Intro and Structures Composites: Bonding together two or more different materials to achieve their combined strength. If a composites Contains a fibrous material encapsulated by a matrix, then it can be called FRP Fiber Reinforced Plastic Advanced Composites: Composite with strength properties greater than a similar composite made with fiberglass material. Laminated Structures: Built-up layers of fibrous material. Sandwich Structures: A structure with core material bonded between two face plate. a. Core material usually has a low density b. Basic examples of core products are: foam honeycomb balsa wood 6. Matrix: A material in which fibers are imbedded. 7. Homogeneous: A structure comprised of the same (one) material. 8.Heterogeneous: A structure comprised of different (more than one) materials. 9. Fiberglass was discovered in the 1930 Before/After WWII. 10 A. Advantages of Composite 1. Strength- to - weight 2.Corrosion Resistance 3. Weather Resistance 4.Resistance to Fatigue 5. Ease of Fabrication and more aerodynamics 6.Impact resistance 7.Fewer Parts 2 8.Greater Stiffness 9 Dimensional Stability B. Limitations of Composites 1.Difficult to repair 2.Cost very high 3.Low conductivity of Electricity 4.Brittles Matrices 5.No yield Point of breaking 6.Safety Hazards 3 7. Temperatures limitations of Matrices 8._Materials May Not be Standardized 11. Laminated Structures built-up layers (or plies) of fibrous material impregnated with a matrix 12. Laminated structures typically have a 60:40 fiber-to- matrix ratio by weight. 13. The two Components of a Laminate: Fibers and Matric 14. Fibers a._______________________________________________________ b._______________________________________________________ c.________________________________________________________ 4 d._______________________________________________________ 15. Matrix a. Major load carrying element of the structures b. Ultimate Strength is in a tensional Load c. Reinforces the Matric d. Possesses Anisotropic Strength 16. Types of Laminates 5 17 Unidirectional Laminate All fibers are oriented in one direction, always have anisotropic properties. 18. Bidirectional Laminate fibers are oriented in two directions, typically has quasi-Isotropic properties. 19. Multidirectional Laminate fibers are oriented in more than two directions, typically has isotropic properties. 21. Types of Strengths/ properties 22. Anisotropic A structure with different properties in all different directions. 23.Isotropic A structure with the same properties in all directions. 24.Quasi-Isotropic A structure with the same properties in two or more directions but not all directions. 25.Warp Clock an engineering symbol used to designate the direction of fibers in a laminate. 6 26.Zero degrees is usually along the main load bearing direction of the part. 27. Symmetrical Laminate A laminate with plies in mirror sequence about the midplane. 28.Balanced Laminate A laminate in which layers oriented in directions other than 0 degrees and 90 degrees are in positive and negative pairs and are symmetrical about the centerline. 29. Construction of Sandwich Structures a.Faceplates Sheetmetal or laminated rfibers b.Adhesives Paste or film c. Core I Beam Construction Concept. 30. Facing acts like flanges of an I- beam 7 31. Core acts like web of an I-beam 8
