Abstract
Polyester has been used as a prosthetic socket base. It is well documented that the raw material of the socket base should have exhibited good mechanical properties. Prosthetic socket is a device that connects an artificial limb with the amputee part. In this work, seven laminated composites were prepared using vacuum technique from polyester resin and reinforced with Jute, Carbon, Glass, and Perlon fibers. The objective of this study is to manufacture prosthetic sockets from different laminated composite materials (fibers reinforced polymer) to make high-strength and durable prosthetic socket design. The results showed that the best laminated composite specimens have three jute fiber layers with four carbon layers whose compression strength and hardness reach (67) MPa and (86) Shore-D, respectively. Also, the water absorption of the composite specimen of jute with carbon fibers is higher than that of the composite specimen of jute with glass fiber.
Highlights
Artificial limbs, known as prostheses, are frequently used to help people who have had limbs amputated regain their appearance and functional activity
From the same figure, it can be noticed that adding the glass fiber to the best lamination leads to increase the compression strength more than the jute fiber alone
This is due to the strengthening mechanism and the nature of bonding. This can be related to the compressive strength of glass fibers and the compressive strength of jute fibers which are much higher than polyester resin
Summary
Artificial limbs, known as prostheses, are frequently used to help people who have had limbs amputated regain their appearance and functional activity. A socket, which surrounds the stump and to which the remaining components of the prosthesis are attached, is typically used to connect the residual limb and the prosthesis [1]. The prosthetic socket is the device that connects an artificial limb with the amputee part [2]. Fiber-reinforced polymer composites are the most widely used multi-phase materials. Most of today's upper and lower limb prostheses are made of composites with the underlying polymer matrix. These types of materials are beneficial because of their excellent strength to weight characteristics [3]. Natural fibers are preferred for their low density, high stiffness-to-weight ratio, low cost, high strength-to-weight ratio, and eco-friendly characteristics [4]. Jute is regarded as one of the most successful reinforcement for polymer composites due to several advantages, including ease of availability, low production costs, and adequate mechanical properties when compared to other fibers [5]
