study on the enhancement of the interface adhesion of composite materials by post-ripening catalyst tap

introduction

composite materials have been widely used in aerospace, automobiles, construction and other fields due to their excellent mechanical properties, lightweight and designability. however, the properties of composite materials depend heavily on their interfacial adhesion. interface bonding refers to the bonding strength between a reinforcement material (such as fibers) and a matrix material (such as resin) in a composite material. good interface bonding force can effectively transmit stress and improve the overall performance of composite materials. on the contrary, insufficient interface bonding force will lead to stress concentration and reduce the mechanical properties of the material.

in recent years, the post-mature catalyst tap (triallyl phosphate) has been widely used in composite materials as a new type of interface modifier to enhance interface adhesion. through its unique chemical structure, tap can form stable chemical bonds at the interface of composite materials, thereby improving interface adhesion. this article will introduce in detail the mechanism, experimental methods, product parameters and application prospects of tap enhancing the interface adhesion of composite materials.

1. chemical structure and mechanism of action of tap

1.1 chemical structure of tap

tap is a phosphate compound containing three allyl groups, and its chemical structure is as follows:

 o
   /
  o o
 /
ch2=ch-ch2 ch2=ch-ch2 ch2=ch-ch2

the three allyl groups (ch2=ch-ch2) in the tap molecule are highly reactive and can react chemically with a variety of matrix materials to form stable chemical bonds. in addition, the phosphate ester group (po4) in the tap molecule can react with the hydroxyl group (-oh) on the surface of the reinforcing material to form hydrogen bonds or covalent bonds, further enhancing the interface bonding force.

1.2 the mechanism of action of tap

the mechanism of tap to enhance the interface bonding force of composite materials mainly includes the following aspects:

  1. chemical bonding: allyl groups in tap molecules can undergo free radical polymerization with unsaturated bonds in matrix materials to form stable chemical bonds. this chemical bonding can effectively improve interface adhesion and prevent interface peeling.

  2. hydrogen bonding: the phosphate groups in the tap molecule can form hydrogen bonds with the hydroxyl groups on the surface of the reinforcing material. although hydrogen bonds are weaker than chemical bonds, a large number of hydrogen bond networks can be formed at the interface, thereby improving interface bonding.

  3. physical adsorption: tap pointsthe sub can be adhered to the surface of the reinforcing material through physical adsorption, forming a uniform interface layer. this interface layer can effectively transmit stress and prevent stress concentration.

2. experimental method

2.1 material preparation

the materials used in the experiment include:

  • reinforcement materials: carbon fiber, glass fiber, aramid fiber, etc.
  • matrix materials: epoxy resin, polyester resin, phenolic resin, etc.
  • tap catalyst: purity ≥99%, molecular weight is 278.2 g/mol.

2.2 experimental steps

  1. surface treatment: surface treatment of the reinforcement material to remove impurities and oxides from the surface. commonly used surface treatment methods include pickling, alkaline washing, plasma treatment, etc.

  2. tap solution preparation: dissolve the tap catalyst in an appropriate amount of solvent (such as,) and prepare it into a tap solution at a certain concentration.

  3. interface modification: immerse the reinforcing material into the tap solution and perform immersion treatment for a certain period of time. parameters such as immersion time, temperature, concentration, etc. shall be adjusted according to the specific experimental conditions.

  4. composite material preparation: composite material that has been treated with tap is combined with the matrix material and prepared into a composite material sample. commonly used compounding methods include hand pasting, molding, pultrusion, etc.

  5. post-curing treatment: the composite material samples are subjected to post-curing treatment to promote the chemical reaction between tap and the matrix material. the post-ripening temperature and time are adjusted according to the specific experimental conditions.

  6. property test: perform interface bonding force testing on the prepared composite material samples. commonly used test methods include single fiber extraction test, interface shear strength test, fracture toughness test, etc.

study on the enhancement of the interface adhesion of composite materials by trimerizing catalyst tap

introduction

composite materials play an increasingly important role in modern industry and are widely used in aerospace, automobile manufacturing, construction and other fields. the performance of composite materials depends to a large extent on their interface adhesion, that is, the bonding strength between different materials. the strength of the interface bonding force directly affects the mechanical properties, durability and service life of the composite material. therefore, how to effectively enhance the interface adhesion of composite materials has become a hot topic in research.

triazine-based accelerator for polymerization, as a new catalyst, has attracted widespread attention in the field of composite materials in recent years. tap can not only accelerate polymerization, but also significantly improve the interface adhesion of composite materials. this article will discuss in detail the application of tap in enhancing the bonding force of composite materials in the interface, including its working principle, product parameters, experimental methods, result analysis and practical application cases.

1. working principle of trimerization catalyst tap

1.1 chemical structure of tap

tap is a catalyst based on triazine ring. its chemical structure contains multiple active groups, which can accelerate the polymerization reaction. the molecular structure of tap is as follows:

chemical structure molecular formula molecular weight
triazine ring c3h3n3 81.07

1.2 catalytic mechanism of tap

tap accelerates polymerization and enhances interface adhesion through the following mechanisms:

  1. the role of active groups: the active groups in tap molecules can react with resin molecules in composite materials to form stable chemical bonds, thereby improving interface bonding.
  2. accelerating polymerization: tap can significantly reduce the activation energy of the polymerization reaction, allowing the reaction to proceed rapidly at lower temperatures, thereby improving production efficiency.
  3. interface compatibility: tap can improve compatibility between different materials, reduce interface defects, and enhance interface adhesion.

2. experimental study on tap enhancing the interface adhesion of composite materials

2.1 experimental materials

2.2 experimental methods

  1. sample preparation: mix the epoxy resin with the tap catalyst in a certain proportion, stir evenly, then apply it to the carbon fiber surface, and then cure it at 80°c for 2 hours.
  2. interface adhesion force test: use peel test method to test the interface adhesion force of the composite material and record the peel strength.
  3. microstructure analysis: use scanning electron microscope (sem) to observe the interface structure of the composite material and analyze the effect of tap on interface adhesion.

2.3 experimental results
