【摘要】 采用碳纤维布和玻璃纤维布与中密度纤维板复合,研究纤维布种类、胶粘剂品种、涂胶量及纤维板基材厚度等因素对纤维增强聚合物/MDF复合板性能的影响。结果表明:对于复合板静曲强度和弹性模量的提高,碳纤维布的效果优于玻璃纤维布;酚醛胶单面涂胶量为180 g/m2时,复合板的MOR、MOE和IB分别达到3 633.8、62.5、1.046MPa;环氧胶单面涂胶量为120 g/m2时,复合板的MOR和MOE分别为3 900.5、49.58MPa;中密度纤维板厚度不同,其静曲强度和弹性模量提高量也不同,FRP对薄板的增强效果优于厚板。更多还原

【Abstract】 The medium density fibreboard(MDF) was reinforced with the GFRP or CFRP,and the effect of FRP type,the variety and dosage of adhesive,the thickness of fiberboard on mechanical properties of FRP/MDF composites were studied.The results showed that the CFRP was better than the GFRP in improving the mechanical properties of MDF;the MOR,MOE and IB of FRP/MDF composites reached 3 633.8 MPa,62.5 MPa and 1.046 MPa when the dosage of PF adhesive was 180 g/m2.Whereas the MOR and MOE of the FRP/MDF composites reached 3 900.5 MPa,and 49.58 MPa respectively when the dosage of Epoxy adhesive was 120 g/m2.The static bending intensity and the increment of plastic quantum of the FRP/MDF composites were influenced by the thickness of MDF,the reinforcement effect of FRP on the thin MDF was superior to that of on the thick MDF.更多还原
