The recycling of thermoset-based composites is challenging. replacement thermosetting resins with thermoplastics an initial step to address this issue, together the use green reinforcements. Owing recent development low-viscosity thermoplastic resins, it possible produce matrix using resin transfer molding (RTM) technique, which was originally conceived for production composites. These are base...

Background and aims. The aim of this study was to compare flexural strength of specimens processed by conventional and injection-molding techniques. Materials and methods. Conventional pressure-packed PMMA was used for conventional pressure-packed and injection-molded PMMA was used for injection-molding techniques. After processing, 15 specimens were stored in distilled water at room temperatur...

Ž This paper describes fabrication techniques for the fabrication of glassy carbon microstructures. Molding of a resin of poly furfuryl . alcohol using elastomeric molds yields polymeric microstructures, which are converted to free-standing glassy carbon microstructures by Ž . Ž 2. heating T ;500–11008C under argon. This approach allows the preparation of macroscopic structures several mm with ...

In response to the defects of easy delamination, poor impact resistance, and low toughness in laminates, intra-layer aramid/glass hybrid weft-knitted reinforced composites without lamination were designed prepared. This paper investigated tensile, bending, composites. Homogeneous with glass: aramid ratios 1:1, 2:1, 3:1, modes transverse hybrid, oblique vertical interlocking prepared by vacuum r...

The quality of Liquid Composite Molding (LCM) manufactured components is strictly related to the fibrous preform impregnation. As Darcy’s law suggests, resin flow influenced by pressure gradient, geometrical features reinforcement, and viscosity. former two parameters are dictated requirements component other constraints; therefore, they hardly modifiable during process. Resin preheating increa...

Objectives: This In-vitro study was designed to compare the Impact strength and Residual monomer content of conventional and high impact types of denture base resins polymerized by Compression and Injection molding technique with short curing cycle. Materials and Methods: Forty samples were made (twenty from each technique)in the dimension of 60 × 10 × 3 with 2 mm notch on the thickness side. T...
