Definitions

• the present invention relates to a nano-reinforced material with steel and ceramic characteristics produced by using polyamide, fiberglass and polyamide aminopropyl silane (PA-GMA) and a method for production of the said material.
• PA-GMA polyamide, fiberglass and polyamide aminopropyl silane
• Masses of the chemical materials used in the inventive polymer supported material and method for production of the said material are lighter than the materials used in the prior art due to their structure and to the interface process transition employed, and their mechanical properties are improved.
• the objective of the present invention is to realize a nano-reinforced material having physical properties similar to steel or ceramics according to preference by using various polymer, fiberglass and nano-combining materials.
• Another objective of this invention is to realize a method for production of a nano- reinforced material with the same chemical properties by reduced production costs.
• Figure 1 is a view of the flow chart of the method for production of the inventive nano-reinforced material.
• the present invention relates to a new production method recommended for production of a nano-reinforced material by using polyamide, fiberglass and polyamide aminopropyl silane (PA-GMA).
• PA-GMA polyamide, fiberglass and polyamide aminopropyl silane
• the said materials should individually wait at the waiting stations at predetermined temperatures and for predetermined periods before production, and are waited depending on the treatment period in order to be freed from the undesired substances present in their structures (101). They are retained stepwise in different stations preferably for 8 to 12 hours at a temperature of 90 to 100 0 C.
• polyamide, fiberglass and polyamide aminopropyl silane are processed by filtered dry and warm air coming from outside.
• the polyamide, fiberglass and polyamide aminopropyl silane (PA-GMA) which are cleaned from the undesired substances therein in sterilized media, and which will be transferred to the machine where combining process will take place after the determined period expires, are subjected to centrifuging before entering into the machine in order to attain a homogenous structure (102).
• the mixture, that attains a homogenous structure enters into the machine where the combining process will be realized.
• the mixture in the machine is primarily subjected to the heat treatment (103).
• the purpose here is to bring polyamide and polyamide aminopropyl silane (PA-GMA) that is the nano-combining material, to a viscosity at which they will be able to melt and combine. While polyamide melts at around 300 0 C, the polyamide aminopropyl silane (PA-GMA) that is used as nano-combining material melts at approximately 28O 0 C. Then, among the elements present in the mixture, firstly the polyamide aminopropyl silane (PA-GMA) that is the nano-combining element melts and later polyamide melts. Since melting temperature of the fiberglass provided in the mixture is approximately 600-650 0 C, rigidity of the said fiberglass does not deteriorate.
• PA-GMA polyamide and polyamide aminopropyl silane
• the polyamide, polyamide aminopropyl silane (PA-GMA) and fiberglass which are at a viscosity suitable for the combination, are combined at a high temperature (104) and molded and cooled to obtain nano-reinforced material (105).
• step (105) After being combined under high temperature and pressure (104), the mixture is cooled step by step (105).
• cooling is realized by gradually reducing temperature values. This is because in order to ensure homogenous orientation within the material, temperature should not be decreased in an instant, but the desired temperature value should be reached by step by step cooling and solidification.
• the molds should be at a certain temperature during molding process (105). This temperature value is preferably 80 to 9O 0 C.
• the fiber glass used in the inventive method for production of a nano-reinforced material ensures that the modulus of elasticity of the newly formed material is more compared to the polyamide used as polymeric material, whereby it makes the nano- reinforced material more rigid.
• modulus of elasticity of the nano-reinforced material realized with the above described production is measured to be approximately 21 GPa. Since modulus of elasticity of aluminum titanate (A12TiO5) which is known in the art with its ceramic characteristics is known to be 5 to 35 GPa, the nano-reinforced material produced according to the above mentioned method has ceramic characteristics due to 50 - 60% aluminum titanate.
• the material when used in high temperatures the material does not undergo the problems that polyamide does at high temperatures when used alone; the fiberglass within the material acts as a ceramic and eliminates heat. Furthermore, the fact that the fiberglass inserted in the material during production is ensured to be distributed optimally in all directions ensures that the modulus of elasticity are close to each other in all three dimensions; and it is observed that the feature of modulus of elasticity of the nano- reinforced material resulting at the end of the production has increased. Thus, when hydrostatic force is applied to the nano-reinforced material it is aimed that the material exhibits the same behavior in all directions until the flow limit.
