초록

The moisture absorption rate and structural strength changes of oven -cured composite skin based on closed molds were studied. Moisture absorption was performed on specimens with and without filler applied. The specimens were exposed to moisture for up to 231 days. Tensile and compression tests were conducted with and without filler application. As a result of the test, the moisture absorption rates of the tensile and compressive specimens without filler were 2.4 and 0.3% higher, respectively, than those with the filler applied. The tensile and compressive strengths of the specimen without filler applied were average 305 MPa and 139 MPa, respectively, and the tensile and compressive strengths of the specimen with filler applied were 313 MPa and 166 MPa, respectively, appeared high.
