COMPOSITE MATERIAL B-BASIS ALLOWABLE SIMULATION BASED ON SMALL SAMPLE PHYSICAL TESTS

Abstract

Abstract: Composite materials are extremely difficult to study due to their complexity, process and manufacturing defects, resulting in great dispersion of materials. The current traditional methods rely on a large number of tests and require extremely high manpower, time and material costs. Using the simulation method, the B-basis allowable of five mechanical properties such as longitudinal tensile, transverse tensile, longitudinal compression, transverse compression and in-plane shear of a carbon fiber composite used in the actual engineering of the institute were calculated and analyzed. The difference between the test and the simulation. The longitudinal compressive strength with large error between the experimental calculation and the simulation results was analyzed, and the transverse tensile strength of the uncalculated test was analyzed. The calculation error is controlled at 5% and the cost is saved.

Key words: carbon fiber composite, B-basis allowable, numerical simulation, low cost
