3 Advantages of Composites
Introduction to Composites Aerospace EngineeringTM Unit 6 - Lesson 6.1: Composite Fabrication Strength-to-weight ratio Long life Dampen vibration Easy to repair Easy to shape Tailored strength characteristics No corrosion Project Lead The Way, Inc. Copyright 2007

4 Introduction to Composites
Aerospace EngineeringTM Unit 6 - Lesson 6.1: Composite Fabrication Composite materials must have 2 basic parts: Reinforcement (fiber) Matrix (resin) All composites MUST have an identifiable reinforcement and matrix. Project Lead The Way, Inc. Copyright 2007

5 Reinforcement and Matrix
Introduction to Composites Aerospace EngineeringTM Unit 6 - Lesson 6.1: Composite Fabrication Reinforcement provides the majority of strength. Matrix holds the reinforcement in a specific orientation, improves environmental properties, and provides some strength. Project Lead The Way, Inc. Copyright 2007

6 Introduction to Composites
Common Composites Introduction to Composites Aerospace EngineeringTM Unit 6 - Lesson 6.1: Composite Fabrication Fiberglass – Most common Graphite – Good strength-to-weight ratio Kevlar – Toughest Boron – Strongest Silicon Carbide – Ceramics reinforcement Project Lead The Way, Inc. Copyright 2007
