Introduction
This lab experiment consisted of two different types of mechanical tests on composite
materials produced in the laboratory. The first of t
The increased use of composites in the engineering industry is no secret. Various engineering
disciplines are seeing increasing use for composites in building materials, and as reinforcements.
This move from traditional building and construction grade met
