With the increased demand for high volume, cost-effective, fiber-reinforced thermoplastic parts, the lack of high throughput systems has become more pronounced. Thermoforming as a method to generate complex shapes from a flat preform is dependable and fast. In order to use readily available, standard unidirectional impregnated thermoplastic tape in this process, a flat perform must be created prior to the thermoforming step. Formerly, creating the preform by hand layup was a time consuming and therefore costly, step. Fiberforge�?s patented RELAY� technology overcomes the challenges of handling thermoplastic prepreg tape and provides a solution through the automated creation of a flat preform, referred to as a Tailored Blank?. Producing a part for thermoforming with accurate ply orientation and scrap minimization is now as simple as loading a material spool followed by a pressing a start button.

With the increased usage of Carbon Fiber Reinforced Plastics (CFRP) in the aircraft industry, there has been increased pressure to improve cutting tool life. Tungsten carbide tools were the first to be applied to CFRP materials. Poly Crystalline Diamond (PCD) tools also became an acceptable material to be used as a cutting tool material. In recent years, Chemical Vapor Deposition (CVD) diamond tools have become more popular as a cutting tool material for CFRP. This study compares these possible cutting tool materials in the drilling of CFRP. Wear is measured as well as hole quality. Life is determined by common industry standards with regard to fiber break out in a common CFRP material. An economic analysis is conducted in order to determine cost per hole.

Abstract The use of nanomaterials and nanostructures have been revolutionizing the advancements of science and technology in various engineering and medical fields. As an example, Carbon Nanotubes (CNTs) have been extensively used for the improvement of mechanical, thermal, electrical, magnetic, and deteriorative properties of traditional composite materials for applications in high-performance structures. The exceptional materials properties of CNTs (i.e., mechanical, magnetic, thermal, and electrical) have introduced them as promising candidates for reinforcement of traditional composites. Most structural configurations of CNTs provide superior material properties; however, their geometrical shapes can deliver different features and characteristics. As one of the unique geometrical configurations, helical CNTs have a great potential for improvement of mechanical, thermal, and electrical properties of polymeric resin composites.
