In this work, a numerical model is developed for simulating the compression molding process of hybrid composite material, alternately laminated with continuous and discontinuous fiber-reinforced layers. Although various simulation models are already available plastic materials embedding each type reinforcements, they incapable simultaneously dealing continuity discontinuity. Here, thermomechani...

PURPOSE The aim of this in vivo study was to compare the single-step border molding technique using injectable heavy viscosity addition silicone with sectional border molding technique using low fusing impression compound by evaluating the retention of heat cure trial denture bases. MATERIALS AND METHODS Ten completely edentulous patients in need of prostheses were included in this study. Two...

OBJECTIVE To evaluate and summarize the evidence comparing nonsurgical therapies in the treatment of infants with deformational plagiocephaly. DATA SOURCES Scientific articles and abstracts published in English between January 1978 and August 2007 were searched from 5 online literature databases, along with a manual search of conference proceedings. STUDY SELECTION Studies were selected and...

Microcellular injection molding using supercritical fluid (SCF) as blowing agent attracts more and more interests. There are still many difficulties in microcellular injection molding, such as decreasing equipment cost, controlling cellular morphology, and increasing feasibility. In this work, primary microcellular injection molding experiments were carried out on newly-developed equipment, whi...

The present paper investigated the impact and compression after behavior of thin carbon fiber epoxy plates manufactured from prepreg platelet molding compound (PPMC) with two different discontinuous length, 25.5 mm 12.7 mm, compared it continuous quasi-isotropic composite laminate a similar plate thickness. results dynamic testing showed that PPMC/12.7 exhibited larger amount absorbed energy, w...

In the present study, silicone rubber reinforced with ketjenblack and barium titanate were fabricated using high temperature compression molding method. These particulate composites are characterized for piezoresistive sensitivity. Ketjenblack conducting dielectric fillers in vulcanized matrix. The effects of fillers, filler loading, amount curing agent, mixing time on properties these investig...

Agglomerated cork composites production has been arising as an alternative eco-friendly to stoppers use and attracts interest create sustainable products materials. A cork-bamboo-latex composite was developed by compression-molding the interaction between three interfaces well their mechanical properties were evaluated density measure, immersion test, FTIR, compression microbial analysis aiming...

During the recent years powder processing technologies have gained much attention due to the less energy consumption and recyclable powders. Manufacturing of complicated parts by the conventional powder metallurgy (PM) method is hard due to the uniaxial pressure, which leads to the low design flexibility. In order to prevail these constraints, powder injection molding (PIM) process, which inclu...
