ASTM D7249 Facesheet Properties of Sandwich Constructions
ASTM D7249 is a widely used test method for determining the facing properties of sandwich constructions using the long beam flexure technique. This test method is essential in industries such as aerospace, automotive, and construction, where sandwich constructions are commonly employed.
GET STARTED
Introduction to ASTM D7249
ASTM D7249 offers a standardized procedure for assessing the facing properties of sandwich constructions. A sandwich construction consists of two facing materials, often called skins, bonded to a core material. This test method focuses on evaluating the performance of the facing materials by subjecting the sandwich panel to a long beam flexure test.
ASTM D7249 test method helps evaluate the mechanical behavior and structural integrity of sandwich panels under bending loads, providing valuable data for design, quality control, and performance assessment.
ASTM D7249 Test Method
The ASTM D7249 test method involves the following steps:
Specimen Preparation
Specimens are cut from the sandwich panel, ensuring they meet the specified dimensions. Specimens are checked for any sharp edges or burrs. The specimens are identified and marked for proper orientation during testing.
Test Setup and Execution
The specimen is placed on supports, ensuring a proper span-to-depth ratio. A concentrated load is applied at the center of the specimen. The load is gradually increased at a specified rate until failure occurs or a predetermined load is reached. The maximum load is applied and any visible damage or deformation during the test is recorded.
ASTM D7249 Specimens
Specimen details
The specimens used in ASTM D7249 are typically rectangular-shaped sandwich panels with specific dimensions.
Specimen dimensions
The dimensions of the specimens are determined based on the requirements of the test and the specific sandwich construction being evaluated.
Specimen preparation
The specimens are prepared by cutting them from the sandwich panel, ensuring accuracy in dimensions and avoiding any damage to the facing materials.
ASTM D7249 Results
The test method ASTM D7249 provides valuable information about the facing properties of sandwich constructions. The maximum load applied during the test is recorded as an indicator of the panel’s strength under bending. Additionally, any visible damage or deformation observed during the test is documented to assess the structural integrity and performance of the facing materials.
