When offshore oil field has been completed and put into production, the new subsea pipelines and cable will need to be established. Cable protection pipe clamp is used to fix cable protection pipe on the jacket. In order to avoid the problem of traditional steel structure clamps which was difficult to joint, align and fasten when it installed cable protection pipe underwater, reduce the risk and workload underwater, This paper will study a new type of portable connecting riser clamp made of resin matrix composites which can solve the installation problem which is difficult to install cable protection pipes underwater. The main structure of pipe clamps made of resin matrix composites used three divided-plates type of structure. The load characteristic of clamps was determined by Morison equation which is a classical theory and clamps underwater mechanics analysis model was established. The results show that the strength of the base of clamps meet the requirements after strength analysis with finite element analysis method, stability and strength experiments, which means the clamps made of resin matrix composite is feasible.

New materials for high performance tribological applications have been one of the major incentives for the development of aluminum-based metal matrix composites (MMCs). MMCs have received attention because of their improved specific strength, good wear resistance, higher thermal conductivity than ceramics, lower coefficient of thermal expansion, etc. Traditionally, lubricant externally added plays an important role in reducing wear in the application of wear resistance materials. However, self-lubricating materials are more desired than materials to which lubricant needs to be applied periodically, especially for wear parts difficult to be accessed, since solid lubricant contained in the former can be released automatically during the wear process and reduces wear.

Resin Matrix Composite

The purpose of this study was to evaluate the color stability of aesthetic restorative resin-matrix materials after their immersion in different dietary and therapeutic solutions. Thirty disc-shaped specimens (10 × 2 mm) were prepared from three different types of resin-matrix composites used in dentistry (BE, FS, AF). The color coordinates (L*a*b*, ΔL*, Δa*, Δa*, Δb* and ΔE*) were measured using a VITA Easyshade 3D-Master (VITA Zahnfabrik, Bad Säckingen, Germany) before and after the immersion of the specimens in coffee, red wine, Coca-Cola®, Eludril Care®, and distilled water solutions for 40 h. The color change (ΔE*) was calculated and analyzed by the Kolmogorov -Smirnov test and the Kruskal -Wallis multiple-comparison test. All the restorative materials showed significant color (ΔE*) changes after their exposure to red wine, followed by coffee and Coca-Cola®; however, one nanohybrid resin-matrix composite showed a high color stability in such colored test solutions. The chemical composition and content of the organic matrix played a key role in the color stability of the resin-matrix composites. Clinicians should advise their patients about the chemical interaction between dietary substances and different resin-matrix composites.

Reinforcement Material

Aluminium based composites exhibit many attractive material properties such as increased stiffness, wear resistance, specific strength and vibration damping and decreased co-efficient of thermal expansion compared with the conventional aluminium alloys. Aluminium Matrix Composites consist of non-metallic reinforcement which offers advantageous properties over base material. Reinforcements like SiC, B4C and Al2O3 are normally preferred to improve the mechanical properties. Here Aluminum LM25 is selected as matrix material while Silicon carbide and Boron carbide are selected as reinforcement material. The fabrication of aluminium matrix was done by stir casting method. In the present study an attempt has been made to investigate the effect of three major stir casting parameters (stir speed, stir duration and preheated temperature of reinforcement material) on stir casting of Aluminium LM25 - SiC - B4C composite. Experiments were conducted based on Taguchi methodology. Taguchi quality design concepts of L9 orthogonal array has been used to determine S/N ratio and through S/N ratio a set of optimum stir casting parameters were obtained. The experimental results confirmed the validity of Taguchi method for enhancing tensile strength of castings.
