Various curing methods on transverse strength of acrylic resin

open access: yesDental Journal, 2010
Background: Acrylic resin were first used in dentistry for denture bases. The basic knowledge of acrylic resin curing method should be known by the dentist, because the improved performance of acrylic resin depends on the curing method.

Effect of binder-aggregate ratio and glass powder on the performance of concrete cured in different media

open access: yesAIMS Materials Science
The current approach to producing concrete is believed to be unsustainable because of its significant consumption of cement and aggregate, thereby causing environmental risks and improper curing of concrete, which could lead to lower durability and ...

Curing kinetics and effects of fibre surface treatment and curing parameters on the interfacial and tensile properties of hemp/epoxy composites [PDF]

open access: yes, 2009
The curing kinetics of neat epoxy (NE) and hemp fibre/epoxy composites was studied and assessed using two dynamic models (the Kissinger and Flynn-Wall-Ozawa Models) and an isothermal model (the Autocatalytic Model) which was generally supported by the ...

One-step volumetric additive manufacturing of complex polymer structures. [PDF]

open access: yes, 2017
Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new volumetric
