表面处理对HDPE/EVA/EG复合材料性能的影响

为了获得热稳定、阻燃和力学性能均较好的复合材料,以高密度聚乙烯/乙烯-醋酸乙烯酯(HDPE/EVA)共混物为基体,可膨胀石墨(EG)作为无卤阻燃剂,通过熔融共混方法制备了HDPE/EVA/EG阻燃复合材料.采用热重分析(TGA)、锥形量热仪、电子扫描电镜(SEM)等方法研究了钛酸酯偶联剂改性前后EG对复合材料的热稳定性能、阻燃性能以及力学性能的影响.研究结果表明, EG能提高聚合物基体材料的热稳定性能和阻燃性能,但力学性能降低;用钛酸酯偶联剂对EG改性后, HDPE/EVA/EG复合材料的断裂伸长率从232.3%提高到315.3%,拉伸强度由9.0 MPa增到了10.0 MPa,冲击强度由88 kJ/m2提高到129 kJ/m2.偶联剂的存在提高了EG与基体间的界面粘结力,使阻燃复合材料的综合力学性能得到改善.

Investigation on mechanism of the improvement in tribological properties of carbon fiber reinforced polytetrafluoroethylene composites by surface treatment

Tribological properties of polytetrafluoroethylene (PTFE) composites filled with differently surface treated carbon fibers (CF), sliding against GCr15 steel under dry sliding conditions, were investigated on a block-on-ring M-2000 tribometer. Experimental results reveal that rare earths (RE) surface treatment reduces the friction and wear of CF-reinforced PTFE (CF/PTFE) composites. Scanning electron microscopy (SEM) investigation of worn surfaces of CF/PTFE composites shows that cracks or pores are visible on the worn surfaces of untreated and air-oxidated composite, while no crack and very few pores present on the worn surface of REtreated composite. The fiber-friction-angling effect makes carbon fibers angled and oriented along the frictional shearing force, and finally parallel to the friction surface, which makes interfacial adhesion become a key factor to tribological properties of CF/PTFE composite. With strong interfacial adhesion between carbon fiber and PTFE after RE surface treatment, carbon fibers are not easily detachable from the PTFE matrix in the process of fiber-friction-angling, which prevents the rubbing-off of PTFE, and accordingly improves the friction and wear properties of the composite.     

A generalized self-consistent model for interfacial debonding behavior of fiber reinforced rubber matrix sealing composites

This paper presents an experimental and numerical study of short-fiber-reinforced rubber matrix sealing composites(SFRC). The transverse tensile stress-strain curves of SFRC are obtained by experiments. Based on the generalized self-consistent method, a representative volume element(RVE) model is established, and the cohesive zone model is employed to investigate the interfacial failure behavior. The effect of interphase properties on the interfacial debonding behavior of SFRC is numerically investigated. The results indicate that an interphase thickness of 0.3 μm and an interphase elastic modulus of about 502 MPa are optimal to restrain the initiation of the interfacial debonding. The interfacial debonding of SFRC mainly occurs between the matrix/interphase interface,which agrees well with results by scanning electron microscope(SEM).

Determination of interfacial heat flux of stainless steel solidification on copper substrate during the first 0.2 s

Interfacial heat transfer is a key issue in many solidification processes. In the paper, a novel experimental apparatus has been designed and on this basis, the instantaneous interfacial heat transfer between molten steel or solidified shell and copper substrate during the first 0.2 s has been studied. The investigated parameters include melt superheat, substrate temperature and surface roughness. The results show that the peak value of the interfacial heat flux in the first stage of liquid/solid contact increases with melt superheat and changes slightly with substrate temperature and surface roughness. The interfacial heat flux in the stage of solid/solid contact has a similar trend of slow decrease in most conditions.
