design and analysis software solutions for composite structures for more than two decades. The software is continuously upgraded to reflect new research findings as well as to capitalize on advances in computing technology. Software applications such as CDS2.0, LIMS and MAT162 are used extensively by researchers at UD-CCM and industrial sponsors to predict material properties and behavior durin...

Global manufacturers of thermoplastic molded parts increasingly require 100% quality inspection levels that are difficult to achieve. While process complexity makes it difficult to attain the desired part properties during start-up, the stochastic nature of the process causes difficulty in maintaining part quality during production. This paper formally compares several alternative quality contr...

Within this research the effect of injection molding temperature on polypropylene (PP)/poly(ethylene terephthalate) (PET) blends and microfibrillar composites was investigated. Injection molding blends (IMBs) and microfibrillar composites (MFCs) of PP/PET have been prepared in a weight ratio 70/30. The samples were processed at three different injection molding temperatures (Tim) (210, 230, 280...

The development of many photonic devices, such as photonic integrated circuit, optical sensors, and photovoltaic devices, demands low-cost and reliable fabrication technologies to fabricate sub-wavelength features. Here, we report a programmable nanoreplica molding process, which is capable of producing photonic devices with a variety of submicrometer patterns. The process utilizes a stretchabl...

Metal powder injection molding is a shaping technology that has achieved solid scientific underpinnings. It is from this science base that recent progress has occurred in titanium powder injection molding. Much of the progress awaited development of the required particles with specific characteristics of particle size, particle shape, and purity. The production of titanium components by injecti...

Injection molding is a critical component of modern industrial operations, and achieving fast stable control injection machines (IMMs) essential for producing high-quality plastic products. This paper focuses on solving an optimal tracking problem the velocity that arises in typical nonlinear IMM. To this end, efficient robust controller proposed designed. The servo system first approximately l...
