Abstract
The utility model relates to polymer matrix composites applied technical field, particularly a kind of five-layer structure vacuum diaphragm with high elongation, compared with prior art, this form film bag is made up of five-layer structure, ground floor is copolyamide, and the second layer is binder resin, and third layer is polyethylene, 4th layer is binder resin, and layer 5 is equal polyester-polyamide; It has good elongation, and elongation is promoted to 500% by of the prior art 300%; Face and add pliability, reduces the vacuum diaphragm caused because of dry climates such as winters and to break hidden danger, greatly reduce manufacturing cost simultaneously, improve the quality of product.
Description
Technical field
The present invention relates to polymer matrix composites applied technical field, particularly a kind of five-layer structure vacuum diaphragm with high elongation.
Background technology
Polymer matrix composites are important component parts for composite, and wherein perfusion/bag compression technology has consequence in numerous technique, and occupation rate rises year by year.Vacuum diaphragm, as the critical material of this technique, plays vital effect, decides the elongation of the quality of product, particularly vacuum diaphragm, directly has influence on the quality of product.
Summary of the invention
For the defect in solution prior art existing for processing of polymer matrix composites and problem, provide a kind of five-layer structure vacuum diaphragm with high elongation.
The technical scheme that the present invention adopts for its technical problem of solution is: the vacuum diaphragm of five-layer structure of the present invention is made up of five-layer structure, ground floor is copolyamide, and the second layer is binder resin, and third layer is polyethylene, 4th layer is binder resin, and layer 5 is equal polyester-polyamide.
The invention has the beneficial effects as follows: compared with prior art, the vacuum diaphragm of five-layer structure of the present invention has good elongation, and elongation is promoted to 500% by of the prior art 300%; Face and add pliability, reduces the vacuum diaphragm caused because of dry climates such as winters and to break hidden danger, greatly reduce manufacturing cost simultaneously, improve the quality of product.
Accompanying drawing explanation
Be described further below in conjunction with the vacuum diaphragm of the drawings and specific embodiments to five-layer structure of the present invention.
Fig. 1 is the cross-sectional view of the vacuum diaphragm of five-layer structure of the present invention.
Detailed description of the invention
As shown in Figure 1, the vacuum diaphragm of five-layer structure of the present invention is made up of five-layer structure, and ground floor 1 is copolyamide, and the second layer 2 is binder resin, and third layer 3 is polyethylene, and the 4th layer 4 is binder resin, and layer 55 is equal polyester-polyamide.
Compared with prior art, the vacuum diaphragm of five-layer structure of the present invention has good elongation, and elongation is promoted to 500% by of the prior art 300%; Face and add pliability, reduces the vacuum diaphragm caused because of dry climates such as winters and to break hidden danger, greatly reduce manufacturing cost simultaneously, improve the quality of product.
The nonrestrictive description according to embodiments of the invention describing the present invention property, but should be understood that when not departing from relevant scope defined by the claims, those skilled in the art can make and changing and/or amendment.
