A-stage resin is a term that is commonly used in the manufacturing and processing of composites. It is a type of thermosetting resin that is used in the production of various materials, including adhesives, coatings, and laminates. In this article, we will explore the definition and meaning of A-stage resin, its origin, and its associations.
Definitions
A-stage resin is a type of thermosetting resin that is in an uncured or partially cured state. It is also known as a pre-polymer or a prepolymer. This means that the resin has not yet fully cross-linked, and it is still able to flow and be shaped. A-stage resin is typically used in the production of composites, where it is combined with other materials to create a final product.
Origin
The term A-stage resin comes from the German word “anfangsstadium,” which means “initial stage.” The term was first used in the 1950s to describe the uncured state of thermosetting resins. Since then, the term has become widely used in the composites industry to describe the partially cured state of resins.
Meaning in different dictionaries
A-stage resin is not a term that is commonly found in dictionaries. However, the term “prepolymer” is often used to describe the same concept. According to the Merriam-Webster dictionary, a prepolymer is “a partially polymerized compound that is used in the manufacture of plastics, resins, or adhesives.” The Oxford English Dictionary defines a prepolymer as “a polymer that has not yet reached its final degree of polymerization.”
Associations
A-stage resin is commonly associated with the manufacturing and processing of composites. It is often used in the production of materials such as fiberglass, carbon fiber, and Kevlar. A-stage resin is also used in the production of adhesives, coatings, and laminates.
Synonyms
A-stage resin is also known as a prepolymer or a pre-cured resin. Other terms that are sometimes used to describe the same concept include partially cured resin, uncured resin, and intermediate resin.
Antonyms
The antonym of A-stage resin is B-stage resin, which is a type of thermosetting resin that is partially cured but still able to flow and be shaped. C-stage resin, on the other hand, is fully cured and cannot be reshaped or reworked.
The same root words
The term A-stage resin does not have any root words, as it is a technical term that was coined specifically to describe the partially cured state of thermosetting resins.
Example Sentences
- The A-stage resin was mixed with fiberglass to create a strong and durable composite material.
- The prepolymer was heated to initiate the curing process and transform it into a B-stage resin.
- The uncured resin was poured into a mold and allowed to cure to create a rigid and stable part.
