Fiber Layup Generation on Curved Composite Structures

Layup Configuration Effect on Notch Residual Strength in Composite Laminates

The current trend shows an increasing demand for composites due to their high stiffness to weight ratio and the recent progress in manufacturing and cost reduction of composites. To combine high strength and stiffness in a cost-effective way, composites are often joined with steel or aluminum. However, joining of thermoset composite materials is challenging because circular holes are often used...

An automated fabric layup machine for the manufacturing of fiber reinforced polymer composite

In the industry of wind turbine blades, the manufacturing of large-scale composite parts is becoming more common. Much effort has been focused on reducing the manufacturing cost and increasing quality by automating the manual layup process. This paper presents a novel automated fabric layup solution based on a new method to deform fiberglass fabric, referred to as shifting, for the layup of non...

Carbonized Starch Microcellular Foam-cellulose Fiber Composite Structures

The production of microporous carbon foams from renewable starch microcellular foam-fiber (SMCF-Fiber) composites is described. Carbon foams are used in applications such as thermal insulation, battery electrodes, filters, fuel cells, and medical devices. SMCF-Fiber composites were created from an aquagel. The water in the aquagel was exchanged with ethanol and then dried and carbonized. Higher...

A New Generation of Composite Materials from Agro-based Fiber

Agro-based fibers are classified according to what part of the plant they come from. Five different fiber classifications will be used in this report: (1) bast or stem fibers, which are the fibrous bundles in the inner bark of the plant stem running the length of the stem; (2) leaf fibers, which run the length of leaves; (3) seed-hair fibers; (4) core, pith or stick fibers, which form the low d...
