摘要

中密度纤维板(MDF)是一种广泛应用于家具行业的木质复合材料。因此,需要对其进行加强。夹层材料是通过在玻璃纤维增强层压板之间插入甘蔗甘蔗渣中密度纤维板,以与三明治相同的方式制成的。采用手工铺层技术,将中密度纤维板置于两层玻璃纤维环氧层压板之间。为了有效地研究中密度纤维板加固过程中的拉伸和弯曲性能,进行了拉伸和弯曲试验。此外,还进行了致密拉伸和中心缺口试样试验,以获得对MDF主材料进行改性对断裂韧性的影响。此外,还进行了水浸泡试验和真菌生物测定抗性研究,以获得一些新的材料环境。结果表明,拉伸和弯曲强度都得到了极大的改善和提高。结果表明,层状材料与中密度纤维板具有良好的相容性和粘结性。这种新型复合材料的断裂韧性试验可以同时满足两种试验要求。该新型材料具有较高的抗真菌性,可用于医疗家具。最后,发现只有一个非常小的百分比的吸收是建立为新的生产材料。

Characteristic properties of glass fiber reinforced sugarcane bagasse medium density fiber board

Medium density fiberboard (MDF) is one of the wood composites which are used widely in the furniture industry. Therefore, its strengthening is required. Sandwiched material is manufactured by inserting sugarcane bagasse medium density fiberboard between the glass fiber reinforced laminates in just the same fashion as a sandwich. A hand lay-up technique is used to prepare the sandwiched specimen, in which the medium density fiberboard plate is put in between two woven layers of glass fiber epoxy laminates. Tensile and bending tests are done to investigate efficiently the tensile and flexural behaviors for the MDF strengthening process. In addition, compact tension and center notch specimen tests are carried out to obtain the effect of the modification performed for the MDF main material on fracture toughness. Moreover, a water soaking test is held out, and fungal bioassay resistance is investigated to obtain some of the novel material environments. The results illustrate that both tensile and flexural strength are extremely modified and increased. Besides, the results show compatibility and bonding between layered material and medium density fiberboard plate. The fracture toughness is greatly increased, and both tests can be met as regards fracture toughness tests for such novel composite material. The novel material has high resistance to fungal creation, which helps it to be utilized in medical furniture. Finally, it is found that only a very little percentage of absorption is established for the novel produced material.
