GB/T1043.1-2008 Determination of impact properties of plastic simple beam - Part 1: Non-instrumental impact test scheme
This scheme applies to the following range of materials:
Hard thermoplastic molding and extrusion materials, including filler materials and reinforced unfilled materials, rigid thermoplastic sheet;
Hard thermosetting molding materials, including filled and reinforced materials, hard thermosetting sheets, including laminates;
Fiber-reinforced thermosetting and thermoplastic composites, including unidirectional or non-unidirectional reinforcements such as felts, fabrics, textile rovings, staple tow, composite and hybrid composites, glass rovings and broken fibers, and prepreg materials Sheet (prepreg);
Thermotropic liquid crystal polymer.
This solution is generally not suitable for hard porous materials and sandwich materials containing porous materials. In addition, long fiber reinforced composites or thermotropic liquid crystal polymers generally do not use notched specimens.
This program is mainly applied to the plastic products enterprises to carry out plastic incoming materials and product quality inspections. The plan includes the objectives of impact tests, relevant test standards, sample types, and typical test equipment for application and test applications.
1, the impact of the test target
The plastic was tested under the specified conditions for the impact strength of the simply supported beam and the basic impact mechanical properties of the plastic material were examined.
The characteristic parameters are:
Unnotched Specimen Simply Supported Beam Impact Strength: The impact energy absorbed when an unnotched specimen is broken. It is related to the original cross-sectional area of ​​the specimen and is expressed in KJ/m2.
Notched Specimen Simply Supported Beam Impact Strength: The impact energy absorbed when a notched specimen breaks is related to the original cross-sectional area at the specimen notch and is expressed in KJ/m2.
