Answer 6

Question 7

classification

particle reinforced

Elastic modulus and application

Answer 7

An elastic modulus is a quantity that measures an object or substance’s resistance to being deformed elastically when a stress is applied to it.

Question 8

classification

fiber - reinforced

Answer 8

Question 9

classification

fiber - reinforced

3 fiber types

Answer 9

Question 10

classification

fiber - reinforced

fiber alignment / continuous vs discontinuous

Answer 10

Question 11

classification

fiber - reinforced

aligned continuous and examples

Answer 11

Question 12

classification

fiber - reinforced

aligned discontinuous and examples

Answer 12

Question 13

classification

fiber - reinforced

critical fiber length

Answer 13

Question 14

composite stiffness

longitudinal loading

Answer 14

To determine the longitudinal load–elongation curve of an artery, the hydrostatic pressure is held constant at a desired value, the length is increased in small steps, and the force recorded.

Question 15

composite stiffness

transverse loading

Answer 15

Transverse loading is a load applied vertically to the plane of the longitudinal axis of a configuration, such as a wind load. It causes the material to bend and rebound from its original position, with inner tensile and compressive straining associated with the change in curvature of the material.

Question 16

composite stiffness

fiber - reinforced

elastic modulus in fiber direction

Answer 16

Question 17

two types of composite production methods

Answer 17

pultrusion - is a manufacturing process for converting reinforced fibers and liquid resin into a fiber-reinforced plastic

filament winding - is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks).
