Course Description

Recently,airplane and space plane were constructed by composite materials such as carbon fiber reinforced plastic. It is important to understand theory and basic knowledge of composite materials for aerospace engineer. Following topics will be lectured.
1. Structure and manufacturing process of fiber reinforced plastics
2. Properties of matrix materials
3. Mechanical properties of composites: rule of mixture and fracture
4. Laminate theory and optimum design
This course will be gain knowledge and method related to DP2.

Course Objectives

What are composite materials? Composite theory based on the elasticity theory will be presented, followed by an overview of carbon fiber and plastics. The goal of this course is to understand the adequate design concept of composite materials and to be able to calculate their properties.

Grading Policy

Fiber and matrix materials will be lectured. Calculation of mechanical properties of composites will be essential.
Final examination (80%) and assignments 20%). Lecture note will be shown in LMS.
