Abstract

The present invention provides a kind of prepreg resin infiltration degree test method, this method is tested mainly for the impregnation degree of vacuum bag pressure curing oven prepreg.The capillary suction phenomenon that the invention can occur when being contacted using dry fibers and water, water rises along the capillary of fiber interfascicular and wetting fibre is until reach saturated water adsorptive value.By the interfiber capillary channel enclosed after resin infiltration, capillarity cannot occur and absorb water, so can use water absorption number judge the contents of dry fibers in prepreg after impregnation, to test the impregnation degree of prepreg.

Description

A kind of prepreg resin infiltration degree test method
Technical field
The present invention relates to field of compound material, the survey of resin infiltration degree specially during carbon fiber prepreg preparation Method for testing.
Background technique
The cured technique of pre-preg vacuum bag can get rid of molding equipment relative to traditional autoclave prepeg process The limitation of autoclave size and its high cost of use.The inside of product and surface matter after the cured molding of pre-preg vacuum bag Amount depends not only on resin formula and resin hybrid technique, also close to the infiltration degree of fiber with resin in prepreg manufacturing process Cut phase is closed.Currently, the method for resin infiltration degree is mainly observed by scanning electron microscope in the prepreg of judgment part both at home and abroad The depth of prepreg thickness direction resin infiltration, this method sampling requirement is higher, can only with the naked eye judge resin in image It is impregnated with depth, lacks the standard of science, the data discrete obtained is too big, cannot function as the test mark of accurate resin infiltration degree It is quasi-.
Summary of the invention
The object of the present invention is to provide a kind of measurement of simplicity parts to be impregnated in prepreg not by the dry fibers of resin infiltration Mass content, come calculating section impregnation prepreg infiltration degree test method, can be realized part impregnation prepreg in set The accurate quantitative analysis of rouge infiltration degree.
Technical solution provided by the invention is：
A kind of part impregnation prepreg resin infiltration degree test method, including：
1) sampling of fabric parent and prepreg parent：It is taken respectively from the both sides and centre of complete width prepreg and fabric Sample, quantity of sampling quantity are 3 groups, i.e. 3 tissue substance parents, 3 groups of prepreg parents；
2) sampling of fabric sample and prepreg test sample：Cut 2 fabric samples respectively on every group of fabric parent, together When 2 prepreg test samples, in total 12 samples are also cut on every group of prepreg parent；
3) bottom of the bottom of fabric sample and prepreg test sample is pasted with pressure sensitive adhesive tape respectively, the two-sided of sample is all pasted There is pressure sensitive adhesive tape, pasting height is Hmm；
4) it weighs respectively to all fabric samples and prepreg test sample, and is averaged to obtain the matter of fabric sample respectively Measure a0With the quality a of prepreg test samplei；
5) fabric sample is hung on the end of bracket, is then placed a stent on balance；
6) by hanging in the water of one end infiltration beaker that the fabric sample of bracket end posts pressure sensitive adhesive tape, immersion depth For H/2mm；
7) after fabric sample sufficiently infiltrates, beaker is removed, then weighs the weight of the fabric sample after infiltration；
8) step 5)-step 7) is repeated, weighs, is averaged after being infiltrated after all fabric samples are all infiltrated The quality b of fabric sample0；
9) fabric sample in step 5) is changed into prepreg test sample, it is same to repeat step 5)-step 7), will own Prepreg test sample all infiltrate after weigh, be averaged the quality b of the prepreg test sample after being infiltratedi；
10) fabric moisture rate w is calculated0=b0/a0With fiber quality f=a total in prepregi*wf, wfIt is fine in prepreg Mass fraction is tieed up, is calculated by the mass ratio of resin and fiber in prepreg manufacturing process；
11) finally calculating resin impregnated degree is
In step 7), when fabric or prepreg infiltrate in water, the reading of balance is paid attention to, to the numerical value of balance Start recording of not beating weight, until the data difference recorded twice in 30 seconds is no more than 0.0002g, as sufficiently infiltration.
The beaker is fixed on iron stand.
Present invention has the advantages that：The present invention makes full use of the capillary suction effect between dry fibers tow, and takes The sample of suitable size and shape controls the saturation absorbent time of fiber, and realization is discrete small, easily to operate, can be online Test to prepreg resin infiltration degree.
Detailed description of the invention
Fig. 1 is that the test sample of prepreg infiltration degree of the present invention prepares schematic diagram.
Fig. 2 is the test device schematic diagram of prepreg infiltration degree of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of part is impregnated with prepreg resin infiltration degree test method, including：

2, the sampling of fabric sample and prepreg test sample：Cut 2 fabric samples respectively on every group of fabric parent, together When also cut 2 prepreg test samples on every group of prepreg parent, i.e. 6 fabric samples, 6 prepreg test samples, in total 12 A sample, the size of test sample are 10.0mm × 30.0mm；
3, it is pasted with pressure sensitive adhesive tape in all test sample bottoms, the two-sided pressure sensitive adhesive tape that must all post guarantees test sample Bottom and water be not impregnated with completely (see Fig. 1) when contacting, pasting height is 10.0mm；
4, it weighs respectively to all fabric samples and prepreg test sample, and is averaged to obtain the matter of fabric sample respectively Measure a0With the quality a of prepreg test samplei；
5, fabric sample is hung on the end of bracket, is then placed a stent on balance, and reset (see Fig. 2), branch The end of frame can use iron wire, and sample can be hung on iron wire end；
6, by hanging in the water of one end infiltration beaker that the fabric sample of bracket end posts pressure sensitive adhesive tape, immersion depth For 5mm；Beaker is fixed on iron stand.
7, after fabric sample sufficiently infiltrates, beaker is removed, then weighs the weight of the fabric sample after infiltration；
8, step 5- step 7 is repeated, weighs after all fabric samples are all infiltrated, is averaged knitting after being infiltrated The quality b of object sample0；
