Abstract
In 90 decade, SEMANN’s company invented the method of SCRIMP to replace the method of Hand lay-up(HLU) traditionally. In 1999,USDDC introduced from USA, it becomed a revolution of manufacture. But they had differences obious between process of manufacture and product by methods of SCRIMP and hand lay-up, for example the pressure of resin, thickness and fiber content etc. . It cause people wanted to study spicemen of differences of mechanical properties by 2 methods.
First, this thesis introduce processes of experiment and tools by SCRIMP, we don’t focus in process of experiment because method of SCRIMP is also wide topic, and to emphasize suggestion of experiment. Then the mechanical properties, tension, bending, fatigue and impact behavior of composite materical manufactured by methods of SCRIMP and hand lay-up are tested. Four types of material test (tension, bending, fatigue and impact) and five kinds of specimens were considered in the experiments
This thesis focus in the fatigue experiment, we studied the fatigue damage processes, fatigue damage modes, fatigue strength and pictures of destruct, then to compared and discussed in the thesis, experimental processes of SCRIMP.
In impact test, our points of view by energy, to compare impact energy of unit area, impact energy of unit wide, we could know which one method could accept higher impact energy, which one specimen of methods belonged destroy of brittle.
The bending load by method of hand lay-up was better than one by method of SCRIMP, the fatigue strength by method of hand lay-up was better, the impact behavior by method of hand lay-up was also better, but ductility by method of SCRIMP was better. The test data may useful for structure design of marine engineer.
