Effect of Reinforcement Alignment to the Properties of Polymer Matrix Composite

Numerous applications have been proposed and demonstrated for producing align-fiber composite. However, none had stated a right procedure to align the fiber to optimize the properties of polymer matrix composite (PMC) such as its strength and water absorption property. Therefore, the aim of this...
