Abstract
The invention provides a wettability testing method for prepreg. The wettability testing method is characterized by comprising the following steps: cutting the prepreg into a test piece with certain area, and fixing the test piece in a hollow cylinder; and if a problem appears during dipping, generating air bubbles on the surface of the test piece, measuring the sizes of the air bubbles, and calculating the bubble number of unit area so as to represent the wettability of the prepreg. The wettability of the prepreg is difficultly represented by a plurality of enterprises; the wettability of the prepreg can be quantitatively tested by the method provided by the invention; effective feedback and guidance can be carried out on production; and the production technology is improved and optimized.
Description
Technical field
The present invention relates to a kind of prepreg wellability method of testing.
Background technology
Prepreg wellability mainly refers to that in production, resin is to the dipping of fortifying fibre, and this index has important impact for the Postforming Technology of prepreg.The performance of prepreg will directly determine the final properties and applications of compound substance, therefore be significant to prepreg quality testing research.
Summary of the invention
The object of this invention is to provide a kind of method that prepreg quality is detected.
In order to achieve the above object, technical scheme of the present invention there is provided a kind of prepreg wellability method of testing, it is characterized in that, prepreg is cut into the test pieces with certain area, then test pieces is fixed on the inside of hollow cylinder, if dipping goes wrong, then have bubble to produce on the surface of test pieces, measure the size of bubble, and the number of bubbles of unit of account area, the wellability of prepreg is characterized with this.
The a lot of enterprise of wellability for prepreg is difficult to characterize, and adopts method provided by the invention to the wellability quantitative test of prepreg, can carry out effective feedback and and guide, improve and optimized production process production.
Embodiment
For making the present invention become apparent, be hereby described in detail below with preferred embodiment.
The invention provides a kind of prepreg wellability method of testing, the steps include: prepreg to be cut into the test pieces with certain area, then test pieces is fixed on the inside of hollow cylinder, if dipping goes wrong, then have bubble to produce on the surface of test pieces, measure the size of bubble, and the number of bubbles of unit of account area, the wellability of prepreg is characterized with this.
Principle of work of the present invention is: if unidirectional pre-immersion material floods bad, surface has minute bubbles, after bending prepreg, can produce minute bubbles equally because flooding bad problem along 0 ° of direction.Therefore, prepreg is cut into certain specification, be attached to inside right cylinder, then test the bubble on prepreg surface.
Prepreg wellability Detection accuracy of the present invention is high, and the problem making prepreg wellability be difficult to characterize is solved.
