Mechanical properties of surface treated UHMWPE fiber and SiO₂ filled PMMA composites

Abstract

The hybrid reinforcement effect of surface-treated UHMWPE fiber and SiO 2 on the mechanical properties of PMMA matrix composites was investigated. When UHMWPE fiber is introduced, the tensile strength of UHMWPE fiber-reinforced composites sharply increases. The flexural modulus was enhanced with an increase in filler loading. Flexural modulus of the treated UHMWPE/SiO 2 /PMMA composites was higher than that of the UHMWPE/PMMA and UHMWPE/SiO 2 /PMMA composites. The outcome of the better interfacial bonding between the filler and the matrix is reflected in the improvement of the mechanical properties of the treated UHMWPE/SiO 2 /PMMA composites.

Research progress on surface modification and application status of UHMWPE fiber

“…It is shown that incorporation of MWCNTs improves the wettability, adhesion, IFSS and tensile properties of fiber-matrix. Tang et al [37] dispersed silica particles in polymethylmethacrylate (PMMA) to form UHMWPE/SiO2/PMMA composites. The increase of bonds of carbon and oxygen indicates that the content of surface-active functional groups of UHMWPE fiber increases, which indirectly proves the reaction on the surface of UHMWPE fiber.…”

Hierarchical structure and properties of high‐density polyethylene (HDPE) microporous films fabricated via thermally‐induced phase separation (TIPS): Effect of presence of ultra‐high molecular weight polyethylene (UHMWPE)

“…), which has been widely concerned by researchers in recent years. [18][19][20][21] However, UHMWPE has been characterized by high viscosity, poor fluidity, and difficult processing, which makes it difficult to be processed by traditional mechanical methods. In view of this, it is nearly impossible to use UHMWPE as a film material alone in current industrial applications.…”

“…Ultra‐high molecular weight polyethylene (UHMWPE), a thermoplastic engineering plastic, has many wonderful properties (e.g., good mechanical properties, good wear resistance and heat resistance, strong anti‐aging ability, good chemical stability, etc. ), which has been widely concerned by researchers in recent years 18–21 …”

Non-isothermal crystallization kinetics of UHMWPE composites filled by oligomer-modified CaCO3

“…Ultrahigh molecular weight polyethylene (UHMWPE) is an excellent thermoplastic crystalline plastic [1][2][3][4]. In comparison with other polyethylene, UHMWPE has lower coefficient of friction [5][6][7], higher mechanical strength [8,9] and abrasion resistance [10][11][12]. Thus, UHMWPE has a wider foreground of application for pipeline industry [13,14], biological medicine [15][16][17], textile industry [18,19] and so on.…”

“…Nevertheless, UHMWPE has extremely high molecular weight so that it is difficult to be processed by common processing method. Aim at this situation, a lot of researchers prepared a series of UHMWPE-based compounds to improve its performance [9,[20][21][22][23][24]. Meanwhile, UHMWPE as a crystalline polymer, addition of other materials can change the crystallization property of UHMWPE, which can influence the UHMWPE performance [25][26][27][28][29].…”
