resin transfer molding (rtm) is a composite manufacturing process. a preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. in this paper, a model is developed to predict the flow pattern, extent of reaction and temperature change during filling and curing in a thin rectangular mold. a numerical simulation is presented to predict the free surface and its inter...

Spanish dry-cured ham is a high quality product whose economic value is mainly given by its curing time. An intense proteolysis takes place throughout the dry-cured processing, which results in the generation of a high amount of peptides and free amino acids responsible for the final quality of dry-cured hams. In this work, a peptidomics approach has been used to study the evolution of peptides...

Objectives were to test the effect of a lowsodium curing solution on processing characteristics of hams from purebred Berkshire pigs that were fed a step-up ractopamine HCl (RAC) feeding program or a negative control diet. Sixty pairs (n = 120) of hams were selected from two blocks of purebred Berkshire pigs (n = 200) that were fed either a control diet or 7.4 mg of ractopamine/ kg of diet for ...

We have studied mortality patterns in a large cohort of rubber workers. We have examined workers exposed to curing fumes, processing dusts, and industrial talc and have begun to evaluate exposures of these workers in detail. Gastrointestinal (especially stomach) cancer appears in excess in processing workers. Lung cancer is excessive in curing workers. Leukemia is increased generally. All three...

The effect of curing agent (6610) content and temperature on the rheological behavior of the epoxy resin CYD-128 was studied by DSC analysis and viscosity experiments. The results show that the resin system meets the requirements of processing technology. A complete reaction occurs when the curing agent content (40 parts per hundred resin, phr) is a little higher than the theoretical value (33....

Mud solids entrained in clarified juice have an adverse effect on subsequent sugar curing and may retard refinery filtration rates if occluded in raw sugar crystals. Entrainment may be caused by refractory juices or instability of process control and may itself lead to unstable processing rates due to retarded curing rates and molasses recirculation. The adverse effects may therefore be quite p...

Among the several available techniques to produce the braided composite rods for construction industry, nidltrusion process is becoming the most widespread and cost-effective continuous processing technique. The work mentions the influence of carboxyl functionalized multiwalled carbon nanotubes (MWCNTs) on the maximum speed of manufacturing process. The epoxy polymer is diglycidyl ether of bisp...

Currently, the drilling fluid processing and recycling has gained more attention from various oilfields. Whether the waste drilling fluid’s processing and recycling is good or not will directly affect the development of oil industry. Therefore, the urgent affair is to develop and research the processing method of waste drilling fluid.This article describes various processing methods of waste dr...

industrial production of thermoset composite components involves the application of a vacuum bagging and autoclave pressure to minimize void percentage, usually to less than 5%. phenolic resin systems generate water as a reaction byproduct via condensation reactions during curing at elevated temperatures. in this paper, vacuum bagging and simple manufactured autoclave curing systems are used fo...

We present a GPU accelerated toolbox for shaping the light propagation through multimode fibre using a spatial light modulator (SLM). The light is modulated before being coupled to the proximal end of the fibre in order to achieve arbitrary light patterns at the distal end of the fibre. First, the toolbox optimises the acquisition time of the transformation matrix of the fibre by synchronous op...
