Abstract
The present invention provides a fiber reinforced composite fiber reinforced fiber reinforced thermoplastic fiber reinforced thermoplastic fiber reinforced thermoplastic composite fiber, A dissipating portion composed of a plurality of second fibers twisted so as to form a gap in the upper and lower reinforcing portions; To a woven fiber reinforcement reinforced with an impact and explosion-proof performance.
Description
The present invention is a lattice-like fiber having excellent adhesion strength to a cement matrix due to its structure and torsion-proofing, as well as a structure in which energy due to external impact and explosion is sufficiently buffered and dissipated, .
Generally, military facilities, nuclear power plants and national main facilities related structures should be resistant to external shocks and explosions. These external shocks and explosions are not safe zones against the collision caused by aircraft malfunction, particularly the South Korean confrontation situation and recent threats to terrorism. Therefore, it is necessary to strengthen the impact resistance against external shocks and explosions, Is important.
At present, it is suggested to increase the wall thickness to increase the thickness of the wall. It is not only economical to increase the wall thickness but also the durability of the temperature crack May occur.
As a technique for developing such a protection and explosion-proof function, Korean Patent Laid-Open Publication No. 10-2012-0014194 discloses a technique for protecting a first outer surface and a second outer surface, which is generally parallel to the first outer surface, Discloses a composite material comprising an inorganic ceramic matrix comprising a surface and at least one open weave glass fiber fabric disposed in an inorganic ceramic matrix between the first and second outer surfaces.
However, according to the above-described technique, there is a problem that the composite material has a deteriorated adhesive strength in the cement matrix. In addition, the energy for external shock and explosion can be buffered to a certain extent, Which is unsuitable as a reinforcing material for protection and explosion-proof.
The present invention has been made to solve the problems of the prior art as described above, and it is an object of the present invention to provide a reinforcing material capable of sufficiently strengthening toughness with excellent adherence to a cement matrix and capable of sufficiently cushioning and dissipating energy for external impact and explosion I want to.
In order to accomplish the above object, the present invention provides a woven fabric reinforcing material reinforced by an impact and an explosion-proof performance, comprising: a pair of reinforcement parts forming a clearance up and down and woven to form a plurality of first fibers in a lattice shape; And a dissipating portion composed of a plurality of second fibers twisted to form a clearance of the upper and lower reinforcing portions.
As one example, the first fiber is composed of a plurality of fiber yarns in the same direction, and the second fiber is formed into a twisted shape of one fiber yarn and is attached to the first fiber at the upper and lower portions thereof and extends in the direction of the first fiber .
In one example, the first fiber is made of hydrophilic fiber and a coating layer is formed on the surface of the first fiber by a hydrophobic surfactant.
Preferably, the hydrophobic surfactant is one or a mixture selected from a polyoxyethylene stearyl ether derivative, a sorbitan fatty acid ester derivative, and a polyoxyethylene oleylamine derivative.
As an example, a gap is formed between a plurality of first fibers and a plurality of second fibers, and the gap is filled with foamed aluminum.
The cement composite structure of the present invention is characterized in that the reinforcing material is disposed between the cement matrixes.
As described above, the weft fiber reinforcing material reinforced with the impact and explosion-proofing properties according to the present invention is advantageous in that the toughness of the cement composite structure can be reinforced due to its strong adhesion to the cement matrix due to its structure.
In addition, the weft fiber reinforcing material reinforced with the impact and explosion-proofing properties according to the present invention is advantageous in that impact resistance is reinforced against external impact and energy dissipation is possible.
In addition, when the composite structure according to the present invention is applied, sufficient impact resistance and explosion-proof performance can be ensured while reducing the amount of SIMMETRIX-embedded styrene, which is economical.
Fig. 1 is a schematic view showing a woven fiber reinforcement reinforced by the impact and explosion-proof performance of the present invention,
Fig. 2 is a structural diagram showing the bonding relationship between the first fiber and the second fiber in the woven fiber reinforcement reinforced by the impact and explosion-proof performance of the present invention. Fig.

On the other hand, the hydrophobic surfactant may be selected from among polyoxyethylene stearyl ether derivatives, polyoxyethylene stearyl ether derivatives, sorbitan fatty acid ester derivatives and polyoxyethylene oleylamine derivatives. It is preferable that the hydrophobic surfactant forming such a coating layer has an HLB value of 3 to 10.
Here, the HLB value is a value indicating the characteristics of the surfactant, and is a value given to the balance between the hydrophilic group and the lipophilic group in the molecules of the surfactant. This value indicates the polarity of the molecules in an arbitrary range of 0.1 to 40. The larger the hydrophilicity, the larger the HLB value. On the contrary, the larger the lipophilic property, the smaller the HLB value.
When the HLB value of the hydrophobic surfactant is less than 3, there is a problem that the hydrophilic group is too small to be adhered to the reinforcing fiber composed of hydrophilic fibers. When the HLB value is more than 10, excessive hydrophilic groups cause strong hydrogen bonding with the cement. . In the present invention, the HLB value of the hydrophobic surfactant is preferably limited to 3 to 10.
The coating layer composed of the hydrophobic surfactant is preferably 0.5 to 2% by weight based on the total weight of the

The reinforcing material mentioned above is placed inside the cement matrix in the composite structure, so that the reinforcing material of the present invention buffers and dissipates energy against the impact from the outside of the structure, thereby forming a safe explosion-proof structure.
On the other hand, in the case of the column, it is proper that the reinforcing member is configured to surround the longitudinal reinforcing bars when the reinforcing material is placed. The reason for this construction is that the reinforcing material has impact resistance and explosion-proof performance, and it is not necessary to dispose a separate spiral reinforcing bar and a reinforcing bar on the column, thereby achieving economical efficiency.
While the present invention has been described with reference to the particular embodiments and drawings, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Various modifications and changes may be made.
