Summary: This standard specifies the use of pultruded reinforced plastic molded test plates preparation methods. The test plate obtained was measured for the processing of laminates mechanical and physical properties of the sample. This method is suitable for the preparation of glass fibers, carbon fibers or aramid fibers (continuous roving, strand, surface mat, fabric or combinations thereof) reinforced thermosetting or thermoplastic resin sheet. Reinforcements can be used alone or in combination. GB/T 27797 and this part of GB/T 27797. 1 used together.

1 Scope

This section GB/T 27797 specifies the preparation of reinforced plastic pultrusion molding method of test plates. The resulting test panels for measuring and processing Specimen given layer mechanical and physical properties of plywood. This method is suitable for the preparation of glass fibers, carbon fibers or aramid fibers (continuous roving, tow, surface mat, fabric or a combination thereof) reinforced thermosetting Or a thermoplastic resin sheet. Reinforcing materials may be used alone or in combination. GB/T 27797 and this part of GB/T 27797.1 used together.

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. ISO 1172 Textile glass fiber reinforced plastic prepreg, molding compounds and laminates glass fibers and inorganic mineral filler content Burning Determination Act (Textile-glass-reinforcedplastics-Prepregs, mouldingcompoundsandlaminates-De- terminationofthetextile-glassandmineralfilercontent-Calcinationmethods) ISO 1268-1 fiber reinforced plastics test plates preparation methods - Part 1. General (Fibre-reinforcedplastics-Meth- odsofproducingtestplates-Part 1. Generalconditions) Health and safety See ISO 1268-1. Principle 4 4.1 pultrusion process is a unique process of molding fiber composites can be molded with a continuous length of a composite material complex geometric cross-section, there are Different fiber content, orientation and arrangement of fiber types. Pultruded profiles usually due to a cross-sectional shape is too small or unsuitable's difficult to cut again Comp verify its performance. If you can not meet the test conditions require obtaining a sample from the production of profiles, it is necessary to use the same raw materials, in accordance with The same process for preparing an alternative flat, then cut the sample from the plate according to the relevant alternative test methods. This section provides this alternate plate Preparation Process. This method can also be used to compare the performance of different profiles at different raw materials and production conditions of production. 4.2 After the reinforcing material impregnated with a suitable resin, pulled through the mold and cured under specified conditions, the preparation of the strip plate. Flat strip should be sufficient Width in order to sample length in the transverse direction of the cut or other specific needs.
